Can You Draw Down Gel Deep Cell Battery To Zero

If yous have washed any research on how batteries piece of work or what yous should look for when selecting the best loftier performance battery, y'all're probably buried in information, some of which is conflicting. At BatteryStuff, nosotros aim to clear that up a bit.

You've almost likely heard the term KISS (Keep It Uncomplicated, Stupid). I'm going to attempt to explain how lead acid batteries work and what they need, without burying yous with a agglomeration of needless technical data. I have establish that bombardment data will vary somewhat from manufacturer to manufacturer, then I will do my best to boil that data downwardly. This ways I may generalize a bit, while staying truthful to purpose.

The pb acid battery has been used commercially for over 100 years. The aforementioned chemical principle that'south existence used to store energy is basically the same equally our neat grandparents used.

A battery is like a piggy bank. If you keep taking out and putting nothing back, yous'll have zero left. Present 24-hour interval vehicle or powersport vehicle bombardment power requirements are huge because all the stock electrical devices that must exist supplied with power. All these electronics crave a reliable source power, and poor battery condition can crusade expensive electronic component failure. Did you know that the boilerplate motorcar has eleven pounds of wire in the electrical arrangement? Expect at RVs and boats with all the electrical gadgets that require ability. It wasn't long ago when trailers or motor homes had merely a single 12-volt firm bombardment. Today recreation vehicles apply their rv batteries to power inverters upwardly to 4000 watts.

Average battery life has become shorter as energy requirements have increased. Life span depends on usage and depth of discharge—usually 6 to 48 months—yet just 30% of all batteries actually reach the 48-month marking. If your unable to maintain the bombardment with an bombardment charger you tin can extend your bombardment life by hooking it upwardly to a solar charger during the off months.

If you can grasp the basics, y'all'll have fewer battery problems and volition gain greater bombardment performance, reliability and longevity. I suggest you read the entire tutorial; notwithstanding, I've indexed all the data for easy reference.

A Few Nuts

The lead acrid battery is fabricated upwards of plates, lead, and lead oxide (various other elements are used to change density, hardness, porosity, etc.), with a 35% sulfuric acid and 65% water solution. This solution is called electrolyte, which causes a chemical reaction that produces electrons. When yous test a battery with a hydrometer, you are measuring the amount of sulfuric acid in the electrolyte. If your reading is depression, that means the chemistry that makes electrons is lacking. So where did the sulfur become? It'due south resting on the battery plates so that when you recharge the battery, the sulfur returns to the electrolyte.

i. You must think prophylactic when you're working around, and with, batteries. Remove all jewelry. (After all, y'all wouldn't want to cook your watchband while y'all're wearing information technology!) The hydrogen gas that batteries make when charging is very explosive. Nosotros have seen several instances of batteries blowing upward and drenching everything in sulfuric acrid. That was no fun, and would have been a skilful time to utilise those safety goggles hanging on the wall. Heck, you lot could even suspension out your disco outfit. Polyester isn't affected by sulfuric acid, but annihilation with cotton volition be eaten upwards. If you lot don't experience the need to brand a fashion statement, only wear junk apparel—after all, polyester is still out of fashion.

When doing electric piece of work on vehicles, it's best to disconnect the ground cable. Only remember that you're messing with corrosive acid, explosive gases and hundreds of amps of electrical current.

2. Basically, there are two types of lead acid batteries (along with three sub categories). The two main types are starting (cranking), and deep cycle (marine/golf cart). The starting battery (SLI starting lights ignition) is designed to evangelize quick bursts of energy (such equally starting engines) and therefore has a greater plate count. The plates are thinner and take somewhat different material composition.

What is a deep bicycle battery?The deep bicycle battery has less instant energy, simply greater long-term energy delivery. Deep cycle batteries accept thicker plates and can survive a lot of discharge cycles. Starting batteries should not be used for deep bicycle applications considering the thinner plates are more prone to warping and pitting when discharged. The and so-called Dual Purpose Battery is a compromise between the two types of batteries, though information technology is amend to exist more specific if possible.

3. Wet prison cell (flooded), gel prison cell, and absorbed glass mat (AGM) are diverse versions of the atomic number 82 acid battery. The wet cell comes in two styles; serviceable and maintenance free. Both are filled with electrolyte and are basically the aforementioned. I adopt one that I can add together water to and check the specific gravity of the electrolyte with a hydrometer.

The gel cell and the AGM batteries are specialty batteries that typically cost twice as much as a premium wet cell bombardment. Even so, they store very well and do not tend to sulfate or degrade as easily as wet prison cell. Although not impossible there is fiddling take chances of a hydrogen gas explosion or corrosion when using these batteries; they are the safest pb acid batteries you can employ. Gel cell and some AGM batteries may require a special charging rate. If you lot want the best and most versatile battery, and then consideration should be given to the AGM bombardment type. AGM batteries are bully for applications such as Marine, RV, Solar, Audio, Power Sports and Stand-By Ability just to name a few.

If you don't use or operate your equipment daily, AGM batteries will hold their charge better than other types. If you must depend on top-notch battery performance, spend the extra money. Gel Cell batteries withal are being sold, but AGM batteries are replacing them in most applications.

At that place is mutual confusion regarding AGM batteries because different articles call them by different names. Some of the more than common names are "sealed regulated valve," "dry cell," "non-spillable," and "valve-regulated lead acid" batteries. In most cases, AGM batteries will give greater life span and greater cycle life than a wet prison cell battery.

SPECIAL Annotation: It's mutual for individuals to use the term "gel cell" every bit a generic term when referring to sealed, maintenance-free batteries, much similar one would utilize Kleenex when referring to facial tissue. As a outcome, we become lots of requests for a gel replacement bombardment or gel bombardment charger when in fact the bombardment is an AGM. For this reason, we always recommend verifying the battery blazon when purchasing a replacement or looking for a charger to maintain the battery.

AGM: The Captivated Drinking glass Mat construction allows the liquid electrolyte to be suspended in a fiberglass matting. This matting surrounds the plate's active textile and in theory this enhances both the belch and recharge efficiency. AGMs are usually manufactured for applications that include loftier-performance engine starting, power sports equipment, deep cycle, solar and storage battery. The larger Deep Cycle AGM Batteries we sell typically offer bully wheel life if recharged before they drib below the 50% discharge charge per unit. When deep bicycle AGM batteries are discharged to a rate of no less than 60%, the wheel life will by and large increment by 300 plus cycles.

The Scorpion motorcycle batteries we comport are a encounter or exceed the specification for the OEM battery. We too carry the Motocross branded batteries for those that have make loyalty to the OEM battery as they are Yuasa'due south aftermarket battery.

GEL: The gel cell bombardment is like the AGM bombardment in the fact that information technology is considered non-spillable, merely the electrolyte is not a moisture liquid. The electrolyte in a gel cell has a silica additive that causes it to ready or stiffen. In well-nigh cases the recharge voltage on gel battery is typically lower than a standard flooded wet cell battery or AGM battery, apart from those made by MK Battery where their 12-volt batteries can accept upwardly to fourteen.half-dozen volts. Nigh gel batteries can simply be charged as loftier equally 14.2 volts per 12-volt battery and are probably the most sensitive battery in terms of adverse reactions to over-voltage charging. Gel Batteries are best used in VERY DEEP bike awarding and may last a bit longer in hot weather applications or awarding where the battery gets excessively discharged. If the incorrect battery charger is used on a gel cell battery, poor functioning and premature failure is certain.

4. CCA, CA, AH and RC. These are the standards that almost battery companies use to charge per unit the output and capacity of a bombardment.

CCA: Cold cranking amps is a measurement of the number of amps a bombardment can deliver at 0°F for 30 seconds and not drop below 7.2 volts. So a high CCA bombardment rating is especially important in starting battery applications, and in common cold weather. This measurement is non particularly important in deep cycle batteries, though information technology is the most commonly "known" battery measurement.

CA: Cranking Amps are measured at 32°F. This rating is also chosen marine cranking amps (MCA). Hot cranking amps (HCA) is seldom used whatever longer simply is measured at 80°F.

RC: Reserve Capacity is a very of import battery rating. This is the number of minutes a fully charged battery at 80°F will belch under a 25 amp load until the battery drops below x.five volts.

AH: An Amp/Hour is a rating commonly constitute on deep cycle batteries and is a capacity rating. The standard rating is a based on how many amps you tin pull out of the battery over a twenty-hr flow. For a 100 AH rated battery this means you can draw from the battery for twenty hours, and it volition provide a total of 100-amp hours. That translates to about v amps an hour (v 10 20 = 100). Nonetheless, information technology'south very of import to know that the total fourth dimension of discharge and load applied is non a linear relationship. As your load increases, your realized chapters decreases. This means if yous discharged that same 100 AH bombardment by a 100-amp load, it would not give you one hour of runtime. On the opposite, the perceived capacity of the bombardment will be that of 64-amp hours.

5. Battery Maintenance: A properly maintained battery is important for the ultimate in service life. Consider these points on a regular basis:

• The battery should be cleaned using a baking soda and water solution; a couple of tablespoons to a pint of h2o.
• Cablevision connections need to be cleaned and tightened every bit battery problems are often caused by muddy and loose connections.
• A serviceable bombardment needs to take the fluid level checked. Apply only mineral-free water; distilled is best equally all impurities have been removed and there is nothing left that could contaminate your cells.
• Don't overfill bombardment cells, especially in warmer weather condition considering the natural fluid expansion in hot weather can push excess electrolytes from the battery.
• To prevent corrosion of cables on pinnacle-mail service batteries, utilize a pocket-size bead of silicone sealer at the base of the mail and place a felt bombardment washer over information technology. Coat the washer with high temperature grease or petroleum jelly (Vaseline), then identify cablevision on the postal service and tighten. Coat the exposed cablevision terminate with the grease. The gases from the bombardment condensing on metal parts causes nearly corrosion.

six. Battery Testing: This tin can be done in more than one style. The most accurate method is measurement of specific gravity and battery voltage. To measure out specific gravity, buy a temperature-compensating hydrometer. To measure voltage, utilise a digital D.C. Voltmeter. A quality load tester may exist a skilful purchase if you need to examination sealed batteries.

For whatsoever of these methods, y'all must first fully charge the battery and and so remove the surface charge. We recommend letting the battery sit down for several hours to remove the surface charge (I prefer at least 12 hours). Letting the battery sit gives you the near accurate result on how the battery will normally human activity. Notwithstanding, if you lot demand to remove the surface charge faster it is possible to belch the bombardment for several minutes. For deep cycle batteries you could only power the device that uses the battery for several minutes. For starting batteries only powering the headlight using the loftier beam can work as well. One time the surface charge has been removed you tin can begin testing.

Country of Charge	Specific Gravity	Voltage
		12V	6V
100%	1.265	12.7	6.three
75%	1.225	12.4	6.2
50%	ane.190	12.2	vi.1
25%	ane.155	12.0	6.0
Discharged	ane.120	11.nine	6.0

Load testing is all the same another way of testing a bombardment. A load tester removes amps from a battery much like starting an engine would. Some battery companies characterization their battery with the amp load for testing. This number is usually half of the CCA rating. For instance, a 500 CCA battery would load test at 250 amps for xv seconds. Nevertheless, most load testers will either allow you lot to input the CCA or in the example of an analog tester it will evidence you a graph the battery should examination at.

A load test should just be performed when the bombardment is at about or total charge. If you don't own or desire to buy a load tester, then simply charge the battery, wait 12 hours, and then accept it to an automotive store for testing. Avoid taking a discharged battery to an automotive store for testing as the test volition only bespeak something you already know.

The results of your testing should be as follows:

• Hydrometer readings should not vary more than .05 differences between cells.
• Digital volt meters should read as the voltage equally shown in this certificate. The sealed AGM and gel prison cell battery voltage (fully charged) will be slightly higher in the 12.8 to 12.nine range. If you have voltage readings in the ten.five volt range on a charged bombardment, that typically indicates a shorted cell.
• If you take a maintenance-complimentary moisture cell, the only means to exam are volt meter and load test. Any of the maintenance-complimentary batteries that have a congenital in hydrometer (black/green window) will tell you the condition of i prison cell of six. You may get a expert reading from 1 cell just have a trouble with other cells in the bombardment.
• When in uncertainty virtually battery testing, call the bombardment manufacturer. Many batteries sold today accept a toll-free number to call for help.

7. Selecting a Battery: When ownership a new bombardment, I suggest you purchase a battery with the greatest reserve capacity or AH rating equally possible. Of course, the physical size and terminal blazon must be a consideration. You may want to consider a gel cell or an absorbed glass mat (AGM) rather than a wet prison cell if the application is in a harsher environment, or the battery is not going to receive regular maintenance and charging. AGM and Gel prison cell batteries typically have a lower cocky-discharge rate and so they can terminal longer when not being maintained.

Exist certain to purchase the correct type of battery for the job it must do. Call back that engine starting batteries and deep cycle batteries are different. Freshness of a new battery is very of import. The longer a battery sits the more dissentious sulfation build upwards there may be on the plates. Virtually batteries have a date of manufacture lawmaking on them. While the date code isn't always credible many manufacturers or dealers will signal the month with a letter, such every bit the letter with "A" being January. The letter is and so followed by a number such every bit "4" corresponding with the twelvemonth 2021. C4 would tell us the battery was manufactured in March 2021. Recollect the fresher the improve. The letter "I" is not used because it can be dislocated with the number ane.

Battery Warranties are figured in the favor of bombardment manufacturers. Let'southward say yous buy a 60-month warranty battery, and it lives 41 months. The warranty is pro-rated, so when taking the months used against the full retail price of the battery you cease up paying nigh the aforementioned coin as if you purchased the battery at the auction price. This makes the manufacturer happy. What makes me happy is to exceed the warranty. Let me assure you it can be washed.

8. Bombardment Life and Performance: Average battery life has become shorter as free energy requirements have increased. 2 phrases I hear nearly often are "my battery won't take a charge," and "my bombardment won't concord a charge." Only 30% of batteries sold today reach the 48-month mark. In fact 80% of all bombardment failure is related to sulfation build-up. This build-upwards occurs when the sulfur molecules in the electrolyte (battery acrid) go and so deeply discharged that they begin to coat the battery'due south lead plates. Earlier long the plates become and then coated that the battery dies. The causes of sulfation are numerous:

• Batteries sit too long between charges. There are ii states when it comes to batteries: They are either being charged or they are self-discharging.
• Battery is stored without some blazon of free energy input. Fifty-fifty if yous disconnect the battery it will yet cocky-discharge.
• "Deep cycling" an engine-starting battery. Remember these batteries can't stand up deep discharge.
• Non completing the charge wheel. Undercharging a battery will allow the sulfation buildup that occurred during discharge to harden. When this happens, it reduces the expanse on the lead plates for the chemical reaction to occur thereby reduces the chapters of the battery.
• Oestrus of over 100°F increases internal discharge. Every bit temperatures increase so does internal belch. A new fully charged bombardment left sitting 24 hours a day at 110°F for 30 days would near likely not kickoff an engine.
• Low electrolyte level. Battery plates exposed to air will immediately sulfate.
• Wrong charging levels and settings. Most cheap battery chargers can practice more than harm than good. See the section on battery charging.
• Cold weather is also hard on the battery. The chemical science does non brand the same amount of free energy as a warm bombardment. Also a deeply discharged battery can freeze solid in sub zero weather. Nosotros recommend gel batteries by MK Bombardment for subzero weather as some of their batteries are rated downwardly to -76°F.
• Parasitic drain is a load put on a bombardment with the key off. Depending on the parasitic load we accept seen batteries discharged in a few days to a few months. We recommend testing your parasitic load then yous know what to expect.

There are ways to greatly increase bombardment life and operation. All the products we sell are targeted to improve functioning and bombardment life.

An instance: Allow'southward say you have "toys" such equally an ATV, classic machine, antiquarian car, boat, Harley, etc. You virtually likely don't use these toys 365 days a year as you do your car. Many of these toys are seasonal, so they are stored. What happens to the batteries? Well-nigh batteries that supply energy to power our toys only concluding 2 seasons. Y'all must go along these batteries from sulfating or buy new ones. We sell products to prevent and reverse sulfar buildup on batteries. The BatteryMINDer products are patented electronic devices that reverse and prevent sulfation. Also Battery Equaliser, a chemical battery additive, has proven itself very constructive in improving battery life and functioning. Other devices such as solar trickle chargers are a great option for battery maintenance.

Parasitic drain: Most vehicles have clocks, engine direction computers, alarm systems, etc. In the example of a boat, you may have an automatic bilge pump, radio, GPS, etc. These devices may all be operating without the engine running. You lot may have parasitic loads caused by a brusque in the electrical organization. If yous are always having dead battery problems, most likely the parasitic drain is excessive. The abiding low or dead bombardment caused past excessive parasitic free energy drain will dramatically shorten battery life. If this is a problem yous are having, check out PriorityStart! battery switches to prevent dead batteries earlier they happen. This special computer switch will plough off your engine kickoff battery before all the starting free energy is tuckered. This technology will prevent you from deep cycling your starting battery.

9. Battery Charging:

Call up, for proper battery maintenance you must put back the energy you utilize immediately.If you don't, the bombardment sulfates, which volition affect performance and longevity. The alternator is a battery charger. It works well if the battery is not deeply discharged. The alternator tends to overcharge batteries that are very depression and the overcharge tin damage batteries. In fact, an engine-starting bombardment on average has only nigh 10 deep cycles available when recharged past an alternator. Batteries similar to exist charged in a sure mode, particularly when they have been deeply discharged. This type of charging is called 3-footstep regulated charging. Please annotation that only special smart battery chargers using computer technology tin perform 3-stride charging techniques. You don't notice these types of chargers in parts stores or large box stores.

1. The first step is bulk charging, where up to 80% of the bombardment energy capacity is replaced past the charger at the maximum voltage and current amp rating of the charger.
2. When the bombardment voltage reaches xiv.4 volts this begins the absorption accuse step. This is where the voltage is held at a constant 14.4 volts and the electric current (amps) declines until the bombardment is 98% charged.
3. Next comes the Bladder Step. This is a regulated voltage of not more 13.4 volts and unremarkably less than 1 amp of electric current. This in time will bring the battery to 100% charged or close to it. The float charge will not eddy or rut batteries, but it will maintain the batteries at 100% readiness and prevent cycling during long term inactivity. Notation: Some gel cell and AGM batteries may require special settings or chargers.

10. Battery Dos

• Remember Prophylactic Starting time.
• Do read entire tutorial.
• Do regular inspection and maintenance, specially in hot weather.
• Practice recharge batteries immediately after discharge.
• Do buy the highest RC reserve chapters or AH amp hour battery that will fit your configuration.

11. Battery Don'ts

• Don't forget safety beginning.
• Don't add together new electrolyte (acid).
• Don't use unregulated, high-output battery chargers to accuse batteries.
• Don't place your equipment and toys into storage without some type of device to keep the battery charged.
• Don't disconnect battery cables while the engine is running (your battery acts as a filter).
• Don't put off recharging batteries.
• Don't add tap water as information technology may contain minerals that will contaminate the electrolyte.
• Don't discharge a bombardment any deeper than you possibly have to.
• Don't permit a bombardment get hot to the touch and boil violently when charging.
• Don't mix size and types of batteries.

While that was a detailed look at bombardment types and how to maintain them, there'southward e'er more to acquire. Check out this additional battery tutorial, and find out more battery basics.
