بطارية بروماستر أوليمبوس LI-90/92B (3.6 فولت/1100 مللي أمبير)

I've been using these as backup for my Olympus on a weekend trip and they've held their charge through a full day of heavy shooting. The 1100mAh capacity feels just as solid as the original battery I had.

My camera battery warning light started flashing halfway through a wedding shoot, but this spare charged to full in under two hours and held steady for over 400 shots.

Camera died on me mid-hike, and this battery got me through another full afternoon of shooting without a hiccup. It holds its charge way better than the two-year-old original I was juggling, so I’m stocking up on a spare.
