To me, both batteries (pana & tp) seem to last equally long leh. Didn't ready bothered and also too lazy to do a comparsion :sweatsm: . Sorry not able to give you guys a good answer :sweat: . But one thing for sure, all digital cameras suck power like an vampire when using only the lcd to shoot :devil: .
I got this battery together with my FZ10 cam from a neighbourhood cam retailer.
Note: Due to some unpleasent experiences in the past in another forum, I will not be naming any shops or where I bought the stuffs.My sincere apology.
Veri big wording/brand indicated in front of the battery box: DIGITAL
Colour of the box: Reddish (colour fading towards the bottom of the box)
Model No: SDV-BM7
Where to get: Selling at many cam retail shops. The best is to get it from the shop where you bought your cam or frequently patronize. Usually most retailers will give their regulars a discount.
Test result: So far so good, using it for several weeks now, can't really find any diff with the pana batt. Both seems to lasts equally long.
