Duracell Olympus BLS-1 Camera Battery

The battery life on this one easily lasts through a full day of shooting, which is exactly what I needed as a backup. It slips in and out of the camera just like the original, and the lithium-ion charge holds up well between uses.

My Olympus camera kept dying mid-hike before, but this spare battery has completely changed my workflow. The lithium-ion cells last impressively long in the field, and I love that it charges up quickly between shoots.

Picked this up as a spare for a weekend trip and it held up through two full days of shooting without needing a recharge. Fits my camera just like the original and the lithium-ion cells seem to keep their charge even when it sits in my bag for weeks.
