Dead after 7 months (Rating: 1 out of 5) No even the only battery, I have the grip and I buy one BP511 from canon and two from Ultralast. The one which came in the camera its dead after 7 months not even with a hard use. The other one, after 12months dead (I use that with my previous 30D)
The ultralast batteries still working good. Just 15$ I pay last year for those, 1600mAh.
Canon is the best (Rating: 5 out of 5) Like others have mentioned, the Canon branded BP511A seems to last longer than the off brands even though capacity is supposed to be equivalent. I have given up on the knock offs priced $20 cheaper because after a few months of usage they don't seem to hold a charge as long whereas the Canon batteries keep going for years. The Canon batteries will still be able to take 500 or more pictures on a charge even after a few years. None of my knock off batteries can do this.
what can i say (Rating: 5 out of 5) i like to use CANON products with my Canon products. It's a great battery and its interchangeable with 2 of my other Canon cameras. My last ones lasted 7 years and 3 years with lots of extreme weather use.
Battery to the rescue (Rating: 5 out of 5) I have an older digital camera and previously ordered what I thought was the correct BP511A battery, nope didn't fit. Returned the wrong size battery and purchased this one and I was so excited that it fitted and now I can take digital photos again.
Best battery for your DSLR! (Rating: 5 out of 5) First party batteries are the the best if you want long life, compatibility, and to avoid any other issues that may arise. The hefty premium is worth the ability to take more shots than those 3rd party brands!
