بطارية Olympus BLH-1 ليثيوم أيون لسلسلة OM-D E-M1

This battery easily lasts through a full day of shooting my E-M1 Mark II, even with plenty of image review. The 1720mAh capacity is noticeably more than my older camera batteries, and it charges reliably without any issues.

I was a bit worried about buying a third-party spare, but this one matches the original Olympus battery's 1720mAh rating and 7.4V output exactly. It slots into my E-M1 Mark II like it was made for it, and the charge lasts just as long as the factory one during a full day of shooting.

The 1720mAh capacity is exactly what I needed for a full day of shooting on my E-M1 Mark II without worrying about the original dying mid-hike. It fits snugly and holds its charge well even after sitting in my bag for a couple weeks. Solid backup, glad I grabbed it.
