The more discharged that a battery is, then the longer it will take to recharge it. Usually it takes several hours to effectively recharge a battery. If a battery is very discharged then it can take up to 12 hours or more to recharge it. While recharging a battery, if the battery becomes hot when you touch it then stop charging it. Slow charge: It is best to slow charge the battery. Slow charging rates vary depending on the battery's type and capacity.
Completely dead Group 24 batteries, though not huge in terms of battery capacity, may still take a few days under a slow/low charge rate to fully charge. Here's how to determine when any given battery is fully charged. While charging, monitor the specific gravity in each cell using a temperature compensated hydrometer.
