As for multi-day trips, the battery of my TZ7 after max. 300 pictures yet, needed a replacement battery. I have first on another marketplace a 100% with the firmware 1.2 'compatible' China-no-name battery purchased. This could be the one without effort and was not recognized by the camera. Then I wrote to the dealer to get another. The new fit indeed better, but was also not detected. Traders should I meant the firmware flash back to 1.1. Then I withdrew from the. The original Panasonic ruled out with my purchase decision. The reasons for this: exorbitant price and customer-unfriendly the manufacturer, I do not want to support Info-Chip policy. So I started looking further a lower but still high quality battery and am found it. The white battery can be used easily and is immediately recognized (with firmware 1.2). He needs 100 minutes for a full recharge. This is enough for about 300-350 images. I notice no difference from the original Panasonic. Have the battery now for several weeks and even in continuous use so far I could not detect any weaknesses.
