I use these batteries in the Canon 5D and Canon 40D.
The 5D is equipped with a battery grip.
Sometimes I catch myself that I want to check the battery, because I do not account for when I have charged the last time.
For a year now I have absolutely zero problems with the power supply.
My total 6 batteries (2x original, 4x Ansmann) are all still at the height of things.
Every now and then I measure the battery through with my profile wire.
This gives me accurate conclusions about the charging time and remaining capacity.
So far I have more than 8 percent loss of capacity, which suggests a good quality of batteries.
Not a single battery deviates from this.
Otherwise I use a lot of Li-ion batteries and also build self-battery packs.
Unfortunately, not all cells equally well.
The Ansmann batteries there have been no problems, the quality assurance of the company seems to be ok.
Conclusion: In my view, strong buy recommendation. Ansmann than large company ensures here for quality. In marked contrast to the no-name products recognizable.
