Quick Answer: What Are Deep Cycle Batteries Good For?

How often should you charge a deep cycle battery?

Batteries should be equalized occasionally to make sure each cell is equally charged.

Apply a controlled overcharge once every 30-90 days, or whenever individual batteries are imbalanced (reading a different voltage or specific gravity).

Check water level before initiating an equalize charge..

Can a car alternator charge a deep cycle battery?

It could take quite some time to fully charge the deep cycle battery. … Also if the deep-cycle battery is very discharged it might not have enough voltage to prime the alternator. The alternator and it’s voltage regulator need like 6 volts to even begin to perk.

What is a deep cycle battery used for?

Deep cycle batteries are batteries that are designed for discharging and recharging such as in RV application, golf cart, floor scrubber, or electric vehicle. Deep cycle batteries as a rule should not be discharged below 80% depth of discharge.

Can you overcharge a deep cycle battery?

Both overcharging and undercharging will have serious adverse effects on the lifespan of a deep cycle battery. In particular, you can seriously shorten the lifespan of a battery if it is used in a deep cycle application that it was not designed for.

How long do deep cycle batteries last?

about 4 to 8 yearsHowever, Flooded Lead-acid deep cycle battery and AGM deep cycle lifespans are about 4 to 8 years, while Gel deep cycle can last up to 2-5 years only.

What is the difference between a marine starting battery and a deep cycle battery?

Deep cycle batteries have thick plates and can be discharged down to 80 percent (deep cycled) time after time without causing damage. In contrast, starter batteries deliver short, high-current bursts to crank an engine, meaning they frequently discharge only a small part of their capacity.

What amp should I charge my deep cycle battery?

It is better to charge a deep cycle battery at a higher charge rate like 6-amps, 10-amps or higher. However, check you battery specifications for the proper charge rate.

Can I run a deep cycle battery and a starting battery in parallel?

The installation can be as simple as connecting two batteries in parallel to make one larger battery bank. … If your starting battery is of the lead-acid type, stick to a deep cycle battery of the same chemistry, instead of choosing a gel or AGM battery with different charging requirements.

How do you load a 12v deep cycle battery?

Place the prongs on the end of the colored wires from your load-tester onto the deep cycle battery terminals as you did using the multimeter, but put them on simultaneously and be prepared to start counting 15 seconds using a wrist watch or a stopwatch. Read the load-tester after 15 seconds.

What should I look for in a deep cycle battery?

What To Look For In A Deep Cycle BatteryWeight & Size. Weight and size are important considerations if you intend to use your deep cycle battery on a watercraft or RV, where you’ll need to run several different electronic applications for extended periods of time. … Charging. … Life Span & Reliability.

Is it bad to drain a deep cycle battery?

Automotive batteries will generally fail after 30-150 deep cycles if deep cycled, while they may last for thousands of cycles in normal starting use (2-5% discharge). Deep cycle batteries are designed to be discharged down as much as 80% time after time and have much thicker plates.

Do I need a special charger for a deep cycle battery?

Using a traditional battery charger to recharge your deep cycle battery will not give you the best possible results. This is because excess heat is produced whenever a battery is charging. A deep cycle battery is not designed to handle the rapid charging and extra heat, so it may never reach full capacity.

How do I know if my deep cycle battery is bad?

How to Know If a Deep Cycle Battery Is BadDo a visual inspection of the battery. … Charge the battery fully before testing. … Have a copy of the manufacturer’s specifications for the battery nearby, as you will need to refer to them as you test the battery.Take a hydrometer reading of all the cells in the battery.More items…

How do I know if my battery is deep cycle?

Typically, a deep cycle battery will have two or three times the RC of a car battery, but will deliver one-half or three-quarters the CCAs. In addition, a deep cycle battery can withstand several hundred total discharge/recharge cycles, while a car battery is not designed to be totally discharged.

Are deep cycle batteries good for cars?

As a general rule, a deep cycle battery will NOT be able to generate enough current output to start your car. It MIGHT work if your car has a very small engine – but AT BEST you are going to kill that battery quite quickly as it’s not DESIGNED for the high current draw starter circuits REQUIRE.

What makes a deep cycle battery different?

The structural difference between deep-cycle and cranking lead-acid batteries is in the lead battery plates. Deep cycle battery plates have thicker active plates, with higher-density active paste material and thicker separators. … The thicker battery plates resist corrosion through extended charge and discharge cycles.
