Use only the charger provided by the manufacturer to charge the battery. Do not overcharge or over-discharge the battery. If the battery starts to swell or emit a strange odor, stop using it immediately and dispose of it properly. Preparing for the Test Before testing
For example, if you have a lithium battery with 100 Ah of usable capacity and you use 40 Ah then you would say that the battery has a depth of discharge of 40 / 100 = 40%. The corollary to battery depth of discharge is the battery state of charge (SOC).
