Can I recharge a deep cycle battery with my car?
Q: Can I use a battery charger designed for deep cycle batteries to charge a regular car battery? Yes you can. … When charging the battery it may take overnight to fully charge depending on the battery charger being used.
What is the best way to charge a deep cycle battery?
Trickle charging is the correct way to charge a deep cycle battery.
Can I use a car charger on a marine battery?
No, the main thing you’ll want to look for is that the charger matches the voltage and chemistry of your boat battery. Any charger that does this will work fine. One of the main advantages of chargers designed specifically for boats is that they tend to be water resistant.
Should you trickle charge a deep cycle battery?
Batteries will self-discharge over a period of months even without a load. Many GEL, AGM and Calcium’s are better than regular lead-acid batteries but even so you should charge them back up regularly, or better still use a trickle charger (or solar panel) to keep them in top condition and extend their life.

How long does it take to charge a 12v deep cycle battery?
As an example of this, if you had a device that pulled 25 amps and you used it for 30 minutes then the amp-hours used up would be 25(amps) x 0.5(hours) = 12.5 amp-hours. The standard and most widely accepted rating period for deep cycle batteries is 20 hours.
How do you bring a deep cycle battery back to life?

How do you tell if a deep cycle battery is fully charged?
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.
