Promaster Minolta / Casio 鋰離子電池：NP-40

My old OEM battery finally gave out, so I grabbed this as a replacement and it's held up through a full day of shooting without a drop in power. The "honest specifications" claim actually checks out — it lasts exactly as long as the original did when new, and it charges in the same cradle with zero

Bought this as a backup for a trip, and it holds a charge just as well as the original. The honest battery capacity rating gave me peace of mind, and it's been months with no drop in performance.

I was a bit worried about third-party batteries, but this one fits perfectly in my Minolta and holds the charge just as long as the original. The battery indicator on my camera reads full right out of the box.
