My battery is getting over charged, it?s not switching to standby soon enough, or the green Led doesn?t stay on?
This can be due to a number of things. If the battery has a faulty cell, then it’s on charge voltage will not reach the charger set point to switch to Constant Voltage Mode, which results in overcharging of the remaining cells, until the overrun timer terminates charge after 18 hours. If there’s a fault in the charger which causes the voltage setting to drift upwards, or if the charger is not set for the correct battery type, that can cause overcharging. In any case, the appropriate test, is to measure the battery voltage when in the constant voltage charge stage, and confirm that the voltage is correct per the specification of the battery. To do this, switch the charger off and on to reset it, and then wait until the “charge” light starts to flash (or, on some units, until the “80%” led comes on. The charger is now in the constant voltage mode. Measure the battery voltage using an accurate digital volt meter, measuring at the battery terminals. If the voltage is too high (for example,
