nameless "brands" battery pack ...

Instead of paid "Photo Primus" was a Noname in unsealed plastic bags. Of course, I immediately sent him back and get my money back - including my postage costs incurred. It is well known that these returns are always connected with a lot of legwork and paperwork leidigem, still be "Handynow" has earned for the rescission of my only duty Stern honestly.

The battery itself gets naturally no praise. As well as if already indicate the two Amazon competitors that this company can no "Photo Primus" sell / allowed ??? Meanwhile I have become smarter ;-) from damage and satisfied owner of two Noname around 4 euros. With realistic capacity indication of 720mAh, 7.4V nominal voltage and obviously pretty fresh production. And super precision fit for my FZ28. (Is this a positive review from me).

A few comments I would like to still make:

1.) Please take a look before buying time under the heading "Lithium ion battery" in Wikipedia over! Because it's clear that advertising messages are fictitious to legendary capacity to 1400 mAh, because the energy density of this battery type can not be increased significantly. This requires a different technology. (Why do you think the Pana-original has only meager 720mAh?!)
You will also find very valuable information at the right storage etc.!

2.) None of replica you can be sure that it fits exactly into its own camera model. I strongly advise not to use the slide in the shaft the slightest violence. Perhaps only a small ridge has to be filed. But please consider well before the procedure, because a return to the dealer is then of course excluded !!!

3.) The "brand" and the Noname are all replicas from China, only the imagination Brand Logo as well as a sales-promoting capacity indication is draufgepappt later the merchants in Germany. Of course, the CE mark. Sadly, that apparently can not do anything against black sheep.

4) Minimum Requirements for electronic equipment (overcharge fuse, overheating protection etc.) comply with all. The most important thing, namely the date of manufacture, they conceal all of us, whether original Panasonic or the numerous replicas. From weighty reason for here is primarily the secret that we should never know customers: age and proper storage are in fact crucial for shelf life, loss of capacity, number of charge cycles .... A year or longer guard the store, a hot summer under tin roof of the warehouse, already ists namely with all promises.

. 5,) ... and again my tip: look Wiki!
