What are the best rechargeable batteries for a digital camera?
Any good brand of rechargeable NiMH battery will do, but make sure they are of a reasonably high capacity (2500-2700mAh). These type of batteries will need to be charged, used and recharged a few times till they reach their maximum charge capacity. Also, their power will drain when not used for some time, so make sure you give then a charge at least a day before you need to use your camera. The S730 uses 2 AA batteries, so buying a set of 4 (plus a 4 battery charger) might be a good option. That way, you always have a spare set on hand if you need them…
