UB1290 9AH version of "APC" RBC2


1 . So whenever I remove multiple old batteries from a UPS, the first thing I do is 
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. 
3. If the charger’s lights rapidly switch between “fully charged” and “charging,” then something’s 
wonky inside the battery, and it’s dead. 
4. But if it charges, and stays charged, put it in the “good” pile.

Been using for some time RBC2 replacement; batteries do not last very long and Batterysharks says if voltage of battery is above 11 then battery is good. I dissagree. Switched to 9 Hr batteries in hopes to get more longevity.
