Question: does it come with a charger? is it compatible with a canon charger? I have a mark ii.
Document: Love this battery, it works just fine. I usually use it as a back up for my canon 5d mark ii, it has worked flawlessly in my tests
I purchased two of these batteries and have been using them for 3-4 months now. They work perfectly in my 5d mark ii (at least as well as my factory Canon battery). Well worth the money and far less expensive than batteries from Canon!
Works just as well as the Canon battery and is A LOT cheaper. It has more mAH as well so it's actually better. Works great on my Mark 5D ii. Without a doubt buy this battery, you won't regret it!
It is the best battery for Canon 5D mark ii.The original battery of 5D mark ii is so expensive. This Wasabi Power battery works great with 5D mark ii, even better than the original batteries.
I have read several reviews that this item may not be compatible with canon 6d. Upon arrival, I tried this several times on my canon 6d and it works like the OEM battery with the advantage of longer battery life. It even works on canon charger without any issues!! !
Wasabi batteries are fantastic. This guy is completely compatible with the original Canon charger and accessories. Lasts longer than the OEM battery at a fraction of the price.
I have 2 of these now for my 5D Mark II and have not had any problems with them holding charge. They both show up fine under the battery info screen, charge in the Canon charger, etc. I've had one of them about 5 months and haven't noticed it developing any problems. For the price I think they're hard to beat.
I bought one of these batteries for my Canon 5D Mark III and it worked perfectly, so I then bought two more and a charger that was also a great deal ( http://www.amazon.com/gp/product/B0049XGNKK/ref=oh_details_o01_s00_i00 ), fast shipping and everything works fine, thank you Amazon and Blue Nook.
When I first got the battery it and put it in my 5D Mark III it read 75% and worked fine. Unfortunately when I try to charge it, the Canon charger blinks slow then rapidly blinks fast. I kept it charging all night and the battery still reads 0%. The charger charges the OEM battery just fine. I'm disappointed because of all the good reviews, I recieved a defective battery.
As a professional photographer for over 13yrs I have used a lot of batteries for various Canon bodies and until I tried this product I have not had good results with off brand replacement batteries. The Wasabi batteries are great though! They charge on the Canon LC-E6 charger just like the LP-E6 and work fine in my Canon 5D Mark II and 7D. I have only done 3 shoots so far with them, but so far so good!!!!
Answer: Hi Shane,I got a 2-pack of Wasabi batteries (no charger) for my 7D (same batteries as 5D II), that were advertised to work with the Canon charger.  One of the batteries died within a couple of months and the other one still works, but doesn't hold a charge as long as my original Canon battery.  Personally, I wasn't particularly satisfied with Wasabi.  Good luck.
