ABSTRACT
The Sony A300/A350 uses the NP-FM500 H, a 7.2 V 11.8Wh lithium-ion battery available for approximately $60. Batteries from the A100 (NPFM55 H) are incompatible with the Sony A300/A350, but the new battery is backward-compatible with the A100 camera. If you plan to shoot a lot, it’s wise to purchase at least one spare battery for your Alpha. Rechargeable lithium-ion batteries are legendary for their long shelf life, so a fully charged battery will still be usable even after several months in the camera bag.
