In Detail:
============
I have been for my Panasonic TZ10 an original Panasonic battery and a no-name battery.
After I had but notice the holiday that two are not enough, if you experimented a lot with the camera, I ordered for my TZ10 two more batteries here from Mumbi.
Amazingly, the two purchased here batteries of Mumbi with my previous no-name battery are absolutely identical because of Mumbi imprint lacking in reality. For the batteries come delivered in an overpack Mumbi print.
Test:
====
To test the performance of the new Mumbi batteries, I've compared it with my one year old Panasonic battery. Both I have fully charged and then be filmed in the power-intensive video setting in the highest resolution all the time ...
Result:
========
My Panasonic battery (1 year old) could afford yet 3x 29min. movies and a 18min. film = 115 min. !!
The Mumbi batteries (new) could each afford 3x 29min. movies and a 22min. film each = 119 min. !!
In this respect, these batteries seem to be similarly efficient here!
However, the performance of the Panasonic batteries was shown on the display a little more evenly: This was at the beginning of the 3rd film of only two bars, while the joining of Mumbi only at the end of the 3rd film to 2 bar. The more astonished I was that these soon moved to a bar and then to battery-end in the 4th movie.
Nevertheless, the overall performance is similar !!
But ...
=======
I was disappointed but the fact that Mumbi mitliefert no battery protection box made of plastic. That was when my other no-name battery case. Since Mumbi ultimately the same no-name batteries sells here, I would choose again the next time the competitor product, although that are rated with half a star bad ... (for whatever reason ...)
So price-performance ratio = 5 stars minus 1 star because no protective box while :-(
