Canon BP511 1100mAh Lithium Ion Battery Pack for Select Digital Cameras and Camcorders

I bought this battery to have as a backup for the identical one that came with my Canon Powershot G5. The battery is fabulous. I've always been very displeased with the shooting capacity of digital cameras in general - they would run out of battery in a very short time. This battery was one of the deciding factors for me buying a Canon Powershot G5. According to a test on dpreview, it's the best performing battery (when used in the G3) out there for any digital camera (at the time of testing). I've taken a few thousand pictures with it so far, and I'm very pleased. When using the LCD display for a mix of movies and pictures (on my G5), I get around 600 pictures out of one fully charged battery. I've never completely "emptied" the battery with the LCD screen off (preview only), but based on my experience so far, I would think that you'll get somewhere between 600-1000 pictures out of one fully charged battery - maybe more - when the LCD is not on all the time. If you take a lot of pictures (I can easily take 500 on a weekend trip), I would still recommend buying an extra battery though. I'm panicked about ever running out of battery (or memory) while I'm shooting. Should you buy a cheaper non-Canon brand equivalent battery? I've not tried an equivalent for the BP-511, but I've got a DigiPower equivalent for my Canon Powershot S200 (Elph II), and it's crap. I would never buy and equivalent for my G5 camera, because in my experience, it's quite apparent that you get what you pay for. Pros: * Extremely good capacity - 500-1000 pictures on one charge with normal use. * Charges relatively quick in my G5 - about 90 minutes Cons: * Very heavy. It'll weigh down your camera, but for the capacity it provides, I personally think it's worth it. Conclusion: It's a very good battery - capacity is fabulous. I've had no problems with it - it doesn't overheat, it doesn't stop working, and so far after about 6 months of operation, I've noticed no drop in capacity. I give it an unconditional 5 stars!!!

Great replacement batterys for the Cannon camera have the same charge as the origional battery. Have had no problems with the battery and seem to last as long as the origional battery at this time . I would order another should the one I have go out

I once tried a chinese look-a-like, but after 1 year the battery broke down, so I bought a genuine Canon to make sure that this one will be doing its job for 8 years, like the first one...

This battery came with my Canon G2 digital camera about 18 months ago and it was very reliable and gave me a couple of hundred shots on a single charge. I bought two additional ones to "be safe" as I was taking a two week cruise of Europe and didn't want to be caught short on power (this was about a year ago). It was not a problem as I rarely needed more than one battery on a day's shoot. But I have found that the three batteries are weakening with continued use and charging. I just came back from a vacation in Hawaii and was finding that I was going deep into a second battery on most days, even though I wasn't taking any more pictures than on my previous trip. I charged up all of my batteries to shoot fireworks for the July 4th celebration and went through one battery very quickly (about 15 minutes) and almost drained a second in another 20 minutes. I think the constant recharging of the batteries have taken a huge toll on them now and they are on their last legs. Given that these batteries aren't cheap, I was hoping they'd last another year or two, but I think that isn't going to be the case. I think some other reviews are bearing this out as well. But when these batteries are at full strength, they are pretty good and reliable. But it looks like that only for a finite amount of time. So if you are getting a Canon product that uses these batteries, you better have at least two on hand and be prepared to have to replace them at some point in he future.

Buyer Beware! I know this information has been included in these reviews before, but I was thinking that Ritz Camera would have fixed things by now. What is offered is "Canon BP511 1100mAh Lithium Ion Battery Pack for Select Digital Cameras and Camcorders" and that is what I want for our Digital Rebel (it was original equipment). What they sent was "Canon BP511A 1390mAh Lithium Ion Battery Pack for Select Digital Cameras and Camcorders" just like they did for another reviewer. This battery has different power ratings because it is intended for a camcorder which has much higher motor driving requirements. When I called to complain, the man on the line told me that it was a better fit for our camera. When I told him that it may be, but I WANT the battery I ordered, he became very insulting and unpleasant. These are not the type of people I want to do business with. I returned the battery and am waiting to see if I get my refund from them. Fortunately I paid for it with a credit card so if they do not refund my money I can dispute the charges. It may be that I cannot get the BP511 and will have to go with the BP511A. But, that battery is available from another Amazon seller for $25 less than Ritz sells it. Again, BUYER BEWARE of the old BAIT and SWITCH!

I have bought third party batteries for a variety of electronic devices over the years, and have learned that there is a price paid in performance cuts that more than makes up for any discount in actual cost. These Canon batteries are more expensive than the hundreds of third party alternatives, but it's because they are the best batteries you can buy for your camera. Highly recommended. I bought one a year ago and it still works like it's brand new.

Fast delivery (3 days) and the battery has been working absolutely fine the 2 days I've been using my camera. Still haven't charged the battery after the first charge. Nice product!

These GENERIC batteries fit well in the camera (Digital Rebel), and work well. But, they don't last even 10% compared to the brand-name battery. They are good for an emergency, when your brand-name battery goes off. Be careful when you purchase these generic kind of batteries with different names. They are all the same, with different names, brands, and prices. I bought 2 of them, with different "characteristics" and names, and received the same twice, and was charged twice for delivery of a single package. Buy the cheapest, is the same as the others.
