I found a nice cheap alternative spare battery for the GX7/LX100. Maybe this is common knowledge, but it was news to me. I was not excited to run generics or pay $45 for a spare BLG10. The old GF3 battery, the DMW-BLE9 is only $11! http://www.amazon.com/Panasonic-DMW...1?ie=UTF8&qid=1424885902&sr=8-1&keywords=BLE9 The ONLY difference between it and the BLG10 is that it is 940mAh vs 1025. So for less than the price of a generic, you can get an genuine Panasonic battery and the only tradeoff is 9% less charge. I've tested it in my GX7 and charger and it works the same. Generic batteries for these cameras say they replace both BLG10 and BLE9, too.
