    About 500 cycle life span.
    Or if the Internal Resistance measurements are going high. Or if the charging voltage doesn't look normal. Old packs heat up more also.
    Guide books aren't part of the packaging.

    i also have a battery that i think needs to be decommisioned i went to charge it and measured the internal resistance, cell 1 and 3 were both under 10 ohms but cell 2 showed-- no reading. so it is open and probably not a safe thing to have sitting around in the house anymore is it?

    the only thing im worried about is the safety of it, i dont really wanna open the pack and attempt to re solder wires, and i think the disconnected cell will become unstable as its charge deteriorates and im not feeling up to a suprise house fire
