I just got a pair of SLAs (B.B. Battery 1.2 Ah's from Digikey). I put a 9V connector on each one. About 1 sec after I connected the first one, the 220uf (PS decoupling, right?) blew. Was it just a fluke? The 16V doesn't leave too much leeway. My MM batts are charging, but I wouldn't be surprised if the 12V SLA is 13.5V unloaded. I think I've got an extra cap, but how likely is it that this will happen again? Should I trot down to Radio Shack and buy their 35V 220uf electrolytics? Any opinions on their quality?
I searched a bit, and it doesn't look like other folks have had problems with SLAs and the stock cap. I know I could just try it again and see, but I hate to do too much as my desoldering skills (and equipment) aren't incredible and I've damaged PCB pads before.
