بطارية Promaster BP-511A ليثيوم-أيون لكاميرات كانون

I was worried about third-party batteries, but this one fits perfectly in my Canon and lasts just as long as the original. The charge holds steady through a full afternoon of shooting, which is all I needed.

This battery held a charge noticeably longer than the old Canon one it replaced, easily lasting through a full afternoon of event shooting. A solid, reliable power source for my camera.

I've used these as backup batteries for my Canon and they hold a charge almost as long as the original. The only small downside is they don't seem to charge quite as fast, but they're reliable enough for a full day of shooting.
