After writing about my new Canon battery I checked availability of the LP-E6 again and found an unbelieveably low price of not quite $14 for two! I could not resist even while fully expecting to write about how bad they were, etc., etc. When the batteries arrived, I was surprised to find that the price included not one but two chargers. I also noticed that the boxes had come apart in shipping; however, all items were in good condition. In the picture above, the new batteries are on the left. I immediately plugged in both chargers; some 45 minutes later both batteries were fully charged.
Both batteries fit my 7D and seem to work. I've not really exercised them -- just casual snaps around the house, maybe 50 shots on each battery. But they do work and have held a charge for several days now.
I don't expect much from these cheap batteries but they do work -- for now anyway.
