The charger works great - showing progress on the charging. However, the batteries very quickly lose their charge even when not in use. I've had these for less than a year and would keep them in my camera bag. On several occasions, I knew they were fully charged in the morning, but by afternoon when I'd pop them in my camera, the batteries were completely exhausted. It happened with both of the batteries in this pack. I threw them both out. Replacing with Sony. They worked well for a short time - perhaps 4-5 months - but then .... I couldn't rely on them.

These batteries work great a while ago I got some batteries from a different company and half way through the shoot I would always have to change them. I did a 1hr and 30min shoot without having to change a single battery battery this is amazing!!

High quality charger. The LEDs show you exactly the charging status for each battery. The charger is small enough that you can throw it into your camera bag and it won't take up a lot of space. The batteries suck, though. After a couple months both batteries got somewhat bloated and it was hard to get them out of the camera. They still hold a charge but since I don't want to risk them blowing up I'm not using them anymore.

i used them since i got the package , but they started to get bigger , they still work , but the quality of the shell is not very good .

Price vs quality

Pretty much love it.

at first they were ok but within a month the battery life went down so quick. They used to die around 30% and the other day they died at 50%… after recording for 5 minutes… after it started at 70%.. after it had been sitting on the charger all night. So either it lost charge sitting in my drawer after I took it off the drawer or they just suck. Or both. Never buying again.
