Promaster Canon BP-975 Li-ion 배터리

Shot an entire wedding on a single charge and still had juice left over, which is more than I can say for the original that came with my camera. The capacity matches the OEM spec exactly and the build feels solid, no flimsy plastic here. For the price, this is a no-brainer backup battery.

I've been using this battery for a few weeks now, and it holds a charge noticeably longer than my old one—even after leaving it in the camera for days. The build feels solid, and it fits perfectly in my Canon without any wobble. Definitely a reliable backup for long shoots.

The capacity on this one matches the original perfectly, and it holds a charge for days even when I’m shooting on and off. I’ve used it in cold weather too and it didn’t drop off like my old one did.
