Koah PRO 2-Pack 1100mAh Battery and Dual Charger compatible with Panasonic DMW-BLG10

The batteries that Panasonic sells for their Lumix cameras are quite expensive. These batteries appear to be a near-exact match to those provided by Panasonic. The charging time is same, the batteries fit the camera without being tight or loose, and I've not experienced any swelling of the battery. They do appear to have slightly less capacity (maybe 20% less) but that's a pretty minor issue. So far, it's been a great alternative that costs dramatically less than the overpriced factory batteries.

Cannot talk about batteries. Ordered for a Lumix camera, checked all the specifications was supposed to work with camera for half the cost. Batteries did not fit into my camera, returned for refund.

Fast, convenient, easy to use. I recently returned from a 15 day stay in Italy. I never was without freshly charged batteries thanks to this handy device. It is compact and easy to take on vacay.

At least equal to our other non Panasonic battery in life, and a possible equal to Panasonic brand at a much better price.
