Depending on the deep cycle rate of the battery will depend on how long you will achive a full charge. With the battery that I have, it will take about 24 hours to charge on the 2 amp setting.f you slow charge (about 2 amperhours) you will not cook the plates that are inside the battery.

It would take a 10 amp charger about 11 hours to recharge a dead battery to near 100% full charge. To calculate your total charge time, a good rule of thumb is to take the amp hour rating of the battery and divide by the charger rating (amps) and then add about 10% for the extra time to totally top off the battery. Some folks wanting quick recharge should look for a charger with more amps.
