Quick Answer: How Should I Charge My Deep Cycle Battery?

What amp should I charge my deep cycle battery?

Considering you have a healthy battery and the battery is completely discharged: For round numbers takes a 150 amp deep cycle battery.

Charge it at 10 amps, you will need to charge that battery for up to 15 hours to fully charge as it puts up to 10 amps in each hour..

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

Whether for marine or auto use, sometimes your deep cycle battery drops below its needed voltage to run your boat, golf cart, or electronics. If this happens, you’ll need a special charger to get your battery back up to its recommended voltage.

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.

What should a fully charged deep cycle battery read?

Voltage on a fully charged battery will read 2.12 to 2.15 volts per cell, or 12.7 volts for a 12 volt battery. At 50% the reading will be 2.03 VPC (Volts Per Cell), and at 0% will be 1.75 VPC or less. Specific gravity will be about 1.265 for a fully charged cell, and 1.13 or less for a totally discharged cell.

Is a marine battery a deep cycle battery?

Marine batteries may be starting batteries, dual-purpose batteries or deep cycle batteries. They are usually a hybrid of starting and deep cycle batteries, with lead sponge plates that are coarser and heavier than starting battery plates but not as thick as true deep cycle battery plates.

How long will a deep cycle battery run a TV?

Well, the 12v tv I have in my caravan runs at 3 amps (36 watts). So on a 120 amp hour AGM (deep cycle) battery, using only 50% of that (the safe discharge limit for deep cycle lead acid batteries), it will run for about 20 hours.

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

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.

Can I charge a deep cycle battery with a regular charger?

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 long do you charge a deep cycle battery?

The time it takes to properly charge a battery depends on its current discharge value and your charger’s amperage specification. A charger with 15 amps, for instance, will take about two hours to fully charge a battery at a 25-percent discharge value.

How long does it take to charge a 100ah deep cycle battery?

approximately five hoursDivide the amp hour rating of your battery by the amp rating of the charger and you’ll have an estimate of the time needed to reach full charge. For example, a 100 amp hour battery at a 50% stage of charge (50 amp hours) would take approximately five hours to charge on a ten amp battery charger.

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…

Is it better to charge a battery at 2 amps or 10 amps?

A basic charger usually charges at around 2 amps – and so needs 24 hours to deliver the 48 amps needed to fully charge a flat, 48 amp hour battery. But there is a wide range of chargers with different charge rates on the market – from 2 to 10 amps. The higher the charge output, the faster a flat battery is recharged.

How many volts should my deep cycle battery have?

A fully-charged 12-volt battery, allowed to “rest” for a few hours (or days) with no load being drawn from it (or charge going to it), will balance out its charge and measure about 12.6 volts between terminals. When a battery reads only 12 volts under the above conditions, it’s almost fully depleted.
