2. Test fit!

I run the battery since mid-June on my 5D MK III as a second battery. Unfortunately, the battery is quickly when not in use out of steam. I know that not so third-party battery's. Reloading the original Canon charger is also only up to 80% possible. The already at just 5 charging cycles.
I start from a defective copy. Unfortunately, I find here on Amazon is no way to complain about the battery because the 30 days have passed. A shame because I expected more because of the many good reviews.

Supplement.
I had shortly after my review contact with the seller and must here say kudos. Absolutely no problem, I have received compensation. I have now made this battery aware some time in operation and wanted to wait before correcting my review, first time a long-term test.
The new battery has a very low self-discharge, which is totally fine by me. Sometimes I get up more than 600 images back on a single charge, even if here and there the Live View is used.
So the second battery can, as yet, fully convince.
My Review I have set up for the mentioned reasons from 2 to 4. One star deduction is because it took 2 attempts it.
Definitely strong buy recommendation from my side.
