Trying to repair a 19,2 volt nicad battery (has 16 1.2v nicad cells in series) (sears)... There's an object in the circuitry of the battery that I believe is a diode.. and maybe a Zener diode.. can't find anything online about what it is exactly.. anyone know what it is or how to calculate what size zener it would require? it's obviously to prevent "backflow" for the charging of battery... I changed a nicad cell in the stack and inadvertantly shorted the diode while doing so... now it won't charge... reads "defective" to the charger...
