NiMh 1.2 volts ?
This is a digital camera question, but I figured this is the place to ask about rechargeable batteries. If this needs to get moved to an off-topic forum, that would be fine...
Here goes. I've been using NiMh batteries in my digital camera for about a year. Fully charged, they test at 1.2 volts. When I put them in my camera, I get a low battery warning almost right away, but I can usually take several pictures (about 30). Recently, the batteries have been discharging very quickly, maybe 5 to 10 pics on fully charged batteries. If I charge them up and let them sit for two days, when I put them in the camera, it won't even turn on. I'm guessing my rechargeable batteries are shot. I plan to buy a new set. Question is, since the NiMh batteries are only good for 1.2 volts, and the camera is really looking for 1.5 volt AA batteries, would I be better off getting NiCad instead? I'm pretty sure my charger will charge the NiCads as well, so it's just a case of buying some new batteries. Thanks, Doug |
RE: NiMh 1.2 volts ?
1) Your batteries are likely toast although you might try using a slow charge to bring them back.
2) NiCd batteries have the same nominal 1.2 V as NiMH so NiCd won't help very much. I suggest that you slow charge the batteries and check the voltage of each one. Check when they are right off the charger and again after they have sat for a day. You may have one bad cell but it is never a good idea to replace a bad cell in an old (weak) pack with one good cell. For safe charging and discharging, all cells need to have the same capacity and (ideally) should be capable of the same discharge rate. Ross |
