WebNov 9, 2024 · A bad battery can show a false voltage when it has surface charge, this occurs for a length of time after a battery has been charging. It can read a full voltage of 12.6 even though it has a bad cell. However, when a battery with a bad cell is put under load, it will immediately fall well below its real voltage of 10.5 volts. Web10.5V is fully discharged, 11.7V is @ 60-70% discharged. You can discharge them down to 80%, @ 11.5V as long as they are brought back up with a charge rate of at least .4C. (.4C is defined as 40% of rated capacity – one G-31 Firefly battery rated at 116 A-Hrs capacity, so periodically it is good to recharge with at least 40-46 amps.
WebApr 1, 2024 · Once the battery is fully charged, the reduced charging voltage is called putting it on “float”. However, even a float charge can cause corrosion of the positive plates.
