The battery and charger on the left is an extra I have left that was used for my now sold 5D3. The battery and the charger on the right came with the R. I understand we can use LP-E6 on R, and I have had no issues using it on the R so far. However, based on the ratings printed on the back of both the chargers, can any of you verify it is safe to charge either batteries (LP-E6 and LP-E6N) in either of the chargers even though the the Wh or mAh is rated slightly different in both the batteries. Thanks.
