Shown in the picture above (L-R) are my original Canon LP-E6, a newly purchased Canon LP-E6 and a copy labeled “Premium Tech”. Also pictured is the Canon charger on the left and the Premium Tech charger on the right. The Canon box for the latest issue LP-E6 is in the middle. The Premium Tech charger can be powered by either AC or automobile battery; the Canon charger is AC only. Both chargers accept 100-240V, 50/60 Hz AC. The new Canon LP-E6 has identical specifications to the one shipped with my 7D but slightly different markings. All three work fine with my 7D.
Because Canon's spare battery was so expensive, I naturally bought a non-OEM spare (only one) along with my 7D. The few times I’ve used it, the non-OEM LP-E6 seems fine and I’m glad to have it. The non-OEM must be recharged in its own charger; I think battery plus charger was about $25.
As I’m beginning to use the 7D for video, another battery seemed to be a good idea (remember that my philosophy calls for three batteries). After reading a few reviews of non-OEM batteries on Amazon, I decided to get Canon’s OEM battery. To my surprise, none were available; however, the supply has now been replenished – but at a higher price. The disparaging reviews on Amazon and discussion forums emphasize that the non-OEM battery cannot be recharged in the Canon charger and that the 7D displays a warning and does not indicate the remaining battery power with a non-OEM battery. Now I have two Canon LP-E6 batteries and a cheap clone.
Last year, I began to write the date of purchase on all my rechargeable batteries, even taking a guess at the older ones, but I’m hoping not to need this information for a long time!
