I have the battery for my TZ-10 from the performance of the battery as well as many others already described quite well. Even for me it is so that quite a long 3 bars are displayed and when he is empty, goes quite fast until it is completely empty. Until here 5 Stars.
But you should watch something, because the battery does not have a temperature sensor or the battery charger and the camera is always a constant temperature of about 23 ° C pretends, no matter what the temperature of the battery really has.
The battery has 4 contacts: plus, minus, one of the "T" and is marked with "D". Behind the "T" is hidden in the normal case with the original Panasonic battery temperature sensor for monitoring the battery. At this contact, the temperature value is passed on to the charger and the camera and in the worst case, if the battery as the charge is overheated then abandoned for safety reasons.
The whole is controlled by a built-in battery resistance realized the value of which varies with temperature, it is possible to value with a multimeter between minus and "T" measure. The original Panasonic battery has at 23 ° C a value of 10,48kOhm, after 20 minutes in the refrigerator is the value 16,4kOhm.
In the "China" battery this value lies both at 23 ° C and after 20 minutes in refrigerator exactly 10,06kOhm. That means it's just a constant resistance installed, the vergaukelt the charger or camera always about 23 ° C ...
I am by another Amazon user who has bought another battery because China joined it, also be China Battery had no temperature sensor ...
Normally, since nothing happens, so probably thinks the maker of batteries and builds Just not a temperature sensor, hundreds, or even thousands use the battery without any problems and it is seemingly nothing happens yet. But just in case could be a temperature sensor, as it has the original battery, prevent the worst, is not for nothing that there is such a temperature monitoring function.
Nevertheless, I then forgive for the good price and the good performance 4 stars, even if the good price clearly at the expense of safety ...
