How often do you use your ES30 camera? Dont go overboard on buying non-rechargeable lithium high capacity batteries. They are quite expensive, though the camera can take a large number of shots before they lose charge. Instead, it might be better to buy high capacity NiMH batteries like the Sanyo Eneloop batteries. Buy four, using two as spare.And turn off the camera if you consciously decide not to shoot for long periods of time. Remove batteries from camera when not in use. Corroded battery terminals due to leaking batteries are the number one source of unusable electronic equipment.
