ProMaster NP-FW50 Sony 鋰離子 7.2V 1100mAh

These batteries fit my Sony camera perfectly and the 1100mAh capacity gives me plenty of juice for a day of casual shooting. I've had no issues with them holding a charge between uses.

Lasted through two full days of shooting landscapes with my Sony, which is way better than the original battery. No sudden power drops, just consistent drain until the very end.

Went a full weekend shooting without needing to swap batteries once, which is way better than my old generic ones. The 1100mAh capacity seems to hold its charge even after sitting in my bag for weeks.
