Question: How Often Should You Charge A Deep Cycle Battery?

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..

Do you need to charge a new deep cycle battery?

New batteries should be given a full charge before use. New deep cycle batteries need to be cycled several times before reaching full capacity (50 – 125 cycles, depending on type). … Batteries should always be watered after charging unless plates are exposed before charging.

What should a fully charged 12v 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.

How long does it take to charge a deep cycle battery at 10 amps?

15 hoursFor 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.

Should deep cycle batteries be trickle charged?

Tips to Maintain a Deep Cycle Battery Don’t leave the battery deeply discharged for an extended period of time. Charge it as soon as your back to shore. Do not store partially charged. Connect a trickle charger to the battery if storing for extended periods of time.

What is the best way to charge a deep cycle battery?

There are two main approaches to charging up a deep cycle battery. The first is to charge the battery while it’s on the boat already, in the fixed position. The second is to take the battery out of the boat and make use of a portable charging unit to top the battery up to full.

How long should you charge a deep cycle battery?

Depending on the physical size, a “deep cycle’ battery may have 80+ “amp hours” (1 amp per hour at 80 hours) of storage capacity. So to charge a deep cycle battery at 2 amps from a “discharged state”, would take around a couple of days (48 hours).

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.

What happens if a deep cycle battery goes flat?

If your battery shows a good voltage when it’s fully charged, but quickly drops voltage to 11V or less when using power, this usually means the battery has a faulty cell and needs replacement. … When a deep cycle battery is fully discharged (dead flat), it should reveal a reading of approximately 10.5V.

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.
