Promaster Panasonic DMW-BLG10

My old OEM battery was starting to die mid-shoot, so I grabbed a pair of these as a backup. They’re built to meet the manufacturer’s specs, and so far the charge lasts just as long as the original did when it was new.

These batteries hold a charge noticeably longer than the generic ones I tried before, and they fit perfectly in my Lumix. It's nice having a spare that I can trust not to die mid-shoot.

I’ve been using these as backups for my Panasonic camera and they last just as long as the original. The capacity hasn’t faded after several months of regular charging cycles.
