Easy enough, right? But if you do this continuously, or even just store the battery with a partial charge, it can cause sulfating. (Spoiler alert: sulfation is not good.)

Even if water is added, the plates should not be covered in water. That white foam stuff holds the water/sulfuric acid and is just "damp".

Myth: The worst thing you can do is overcharge a lead acid battery. Fact: The worst thing you can do is under-charge a lead acid battery. Regularly under-charging a battery will result in sulfation with permanent loss of capacity and plate corrosion rates upwards of 25x normal.
While charging a lead-acid battery, the following points may be kept in mind: The source, by which battery is to be charged must be a DC source. The positive terminal of the battery charger is connected to the positive terminal of battery and negative to negative.
Nowadays modern plastics are impervious to acid so there is no risk of this happening. Myth: It is okay to store lead acid batteries anywhere inside or outside. Fact: It is good to store lead acid batteries in cool places because the self-discharge is lower but be careful not to freeze the battery.
As with all other batteries, make sure that they stay cool and don't overheat during charging. Sealed lead-acid batteries can ensure high peak currents but you should avoid full discharges all the way to zero. The best recommendation is to charge after every use to ensure that a full discharge doesn't happen accidently.
Proper monitoring during charging is crucial for safety and performance. Lead-acid batteries produce hydrogen and oxygen gases as they charge, particularly in the later stages of charging. These gases can accumulate and become hazardous if not properly ventilated.
