+ | shake them individually. If they rattle, they’re dead. Go ahead and toss recycle them (in fact, | ||
+ | some battery stores will pay you for your dead RBC-style batteries). | ||
+ | 2. If they pass the shake test, I connect them to one of my CTEK 12 volt battery chargers (any | ||
+ | car charger will do – car batteries are also 12 volts). If my charger doesn’t light up, it means | ||
+ | the battery’s posts aren’t connected internally, and so the battery is dead. | ||
