Keep in mind that a faster self-discharge rate is not always bad if your tools are never stored away for long periods between use then you probably wont care about the self-discharge rate at all. Thanks for contributing an answer to Electrical Engineering Stack Exchange! You will find that Lead Acid batteries can be charged in many different ways, but it is always best to follow the manufacturers instructions and use the charger that the manufacturer provided with the tool. English; ; ; Filipino; Malay; Thai; Ting Vit; US Dollar ($) small remainder can be used by any devices outside the battery. quickly to boiling, and the metal surface might even melt or start If it fits, then yes you can. Are either of us correct? Would this design carry too much current and damage battery charger ICs? I am not sure about this particular battery, but I have seen two uses for third battery pin: battery detection. Float Voltage - The voltage at which the battery is maintained after being charge to 100 percent SOC to maintain that capacity by compensating for self-discharge of the battery.
