My previous camera was standard batteries / accumulators, which could be easily replaced. Now I bought a Panasonic TZ61 and it has a proprietary battery. So I thought about what I should do now? At first I wanted to buy a charger, but then came the idea of starting again. Firstly, I need it to have some further battery, on the other hand it is an additional larger part in his luggage. Then I discovered this double pack with the original capacity in 1.klassiger quality. So I've always 3 batteries on the go and then upload the evening again in the camera. That these batteries fit perfectly in my camera is almost a matter of course. What more could you 2 class batteries at half the price of the original and cost about as much just a charger equal. Absolute buy recommendation!
