# Quick Answer: How Long Does It Take To Charge A Deep Cycle Battery At 10 Amps?

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

about 6 hoursThe same battery will take about 6 hours to fully charge if the charge rate is 10 amps.

The lower the open-circuit voltage in the battery and the more cold-cranking amps, the longer it will take to charge the battery..

## Can you overcharge a deep cycle battery?

Overcharging Deep Cycle Batteries: As a result of too high a charge voltage excessive current will flow into the battery, after reaching full charge, causing decomposition of water in the electrolyte and premature aging. At high rates of overcharge a battery will progressively heat up.

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

Batteries usually take several hours to recharge; if the battery is severely discharged (12.2 volts or less for an flooded battery) then it may take up to 12 hours or more to recharge.

## What is the best amperage to charge a car battery?

10 ampsA 12 volt / 10 amp 3-stage automatic charger is the best charger for most automotive batteries. Unfortunately most chargers do not output the entire 10 amps during the charge cycle, because it automatically limits the voltage and the amperage during the charge cycle.

## 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.

## Is it safe to charge a car battery at 10 amps?

As for car batteries, it is a rule of thumb not to fast charge them using anything that exceeds 20 amps. Slow charging using 10 amp chargers or less is generally accepted to be better. This is because repeatedly fast-charging a car battery may lead to overcharging and will severely reduce its performance.

## How long does it take to charge a 12 volt battery at 10 amps?

To determine how long (in hours) you will need to charge your battery, divided 36 by 10 = 3.6 or 3.6 hours to recharge your battery. A 12 volt / 10 amp 3-stage automatic charger is the best charger for most automotive batteries.

## How many times can you charge a deep cycle battery?

New batteries can take up to 50 charge/discharge cycles before they reach their rated capacity. Depending on your application, batteries with 80% or less of their original capacity are considered to be bad.

## Can you charge a deep cycle battery at 10 amps?

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. It’s never good to over charge a battery, as your solution will start to boil out.

## Should you trickle charge a deep cycle battery?

Set your battery charger to a slow or trickle charge and select whether you are charging a 6, 12 or 24 volt deep cycle battery. If your battery charger has the option to set the voltage for the charge, set it to 20 percent of the rated amp per hour rate of the battery you are charging.

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

Automatic battery chargers adjust their own settings according to the battery they are charging so they can recondition batteries that are becoming corroded and they can charge batteries without causing any damage to the batteries. An automatic battery charger is highly recommended for all deep cycle batteries.

## How often should I charge my deep cycle battery?

Program your voltage set points so that the battery bank charges at the proper voltage. Refill flooded lead-acid batteries with distilled water every 2-4 weeks as needed. Regularly check battery state of charge. Apply an equalization charge to flooded batteries every 90 days.

## 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.

## What is the best amperage to charge a 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.

## Should I charge my car battery at 2 amps or 6 amps?

In answer to your question, the six amp charger will charge your battery three times faster than the two amp charger. Six amps is stil a relatively slow charge and should be fine to use for a deep cycle battery. If your charger is telling you the battery is full, place a load on the battery before charging it.

## Can you overcharge a battery at 2 amps?

A: If you leave the charger connected continuously, even at a mere 2 amps, the battery eventually will die. Overcharging a battery causes excessive gassing — the electrolyte gets hot and both hydrogen and oxygen gas are generated. … Charging your battery at the 10-amp rate is fine to get your battery back into service.

## How long do you charge a 12 volt deep cycle battery?

Determining Charge Time. The more discharged that your battery is, the longer it will take to recharge it. Batteries usually take several hours to recharge; if the battery is severely discharged (12.2 volts or less for an flooded battery) then it may take up to 12 hours or more to recharge.

## Can I leave a car battery charger on overnight?

Even though there is no risk of overcharging with the use of a high quality charger, the battery should not remain connected to the charger for more than 24 hours. A full charge is usually achieved by charging overnight. … Even after a deep discharge, some chargers enable at least partial reconditioning of the battery.
