Promaster オリンパス BLH-1 用 リチウムイオンバッテリー

After a full day of shooting, this battery still had 20% left, which is way better than my old one. The charge held steady even in cold weather, no sudden drops. Feels solid and fits perfectly in my camera.

Started using this in my camera for a long hike and the battery held its charge much better than I expected, even after sitting unused for two days. The build quality feels solid and it fits perfectly in the compartment, no wobble at all.

Charges my camera just as fast as the original, and the battery holds its charge for days even when I leave it sitting in the bag. I’ve already used it through a full weekend of shooting without needing to swap out.
