My initial full charge had been almost a month old before first use in real-world winter conditions. The pre-warmed battery performed well in sub-freezing temps. I would buy a CTA brand 1500ma model BP-511 battery again.

The battery did not work from the moment I received it. And to send it back would cost almost as much as the battery itself did.

I am not pleased with this particular product. The charge just did'nt last. I know this product as being inferior, totally the opposite of other products that I have purchased from Overstock.com.

This is a great product. In the retail stores you would pay about $40-$50 more for the same product. My battery worked perfectly and is still I bought two of them to go with my Cannon. Great replacement.

The battery matched the item description perfect. i fully charge it and have no problems shooting for days without any problems, it sure beats getting the original at a much higher price. Why pay more, a battery is a battery.

• Did the image onsite match the product? yes, perfect
• Was the product free of any manufacturer defects? no problems
• How is the quality of the product? awesome, i have another spare battery at a great price

I purchased a non-canon battery from another company and it was no where near the quality of this one. This works well and is a great value.

This Camera battery is exactly the same as the cannon but it was more than half off the price for the original one I am buying another one just so when I need it I will have it.! love overstock I will always check there first for the things I need!

It is a replacement battery, it was a good buy. Same battery at stores go for about $50, so this is definitely a deal, i might buy another one, before they run out

I have used CTA made BP-511 for my Canon cameras for a couple of years and have found them the equal of the Canon brand but alot less expensive. I have used these batteries in Canon's EOS 10D, 20D, 40D and 5D. They seem to hold a charge very well and I think are a very good battery.. This is my favorite brand of non Canon batteries.

I wish I had more needs to buy from this company. Value and service is top notch. I had shopped many other battery sites and always something was wrong. The batteries charged perfectly and were correct size. Sometimes 3rd party batteries fit too tight, these were perfect.

I have bought this product from Overstock before and was happy with it. I expect to be happy with this battery as well. It does not last as long as the Canon battery, but costs about $50 less.

Same battery at a $ 40.00 savings. Made buy oem & sold with great savings

This battery fits and works perfectly in my Canon Rebel digital camera. The cost was very reasonable compared to chain store prices.

The batteries arrived quickly, after charging photographed 13 little league teams with 120 kids and did not need a recharge or swap out of batteries..Batteries were ready to photograph a few more teams.

Great value for extra battery to have on hand when taking losts of photos. Charging time seems to be same as original battery that came with camera.

Pro: The cheap one, and quality is ok. problem: none so far.

have not tested it out all the way but so far very good.

I bought this as a spare, it's a great buy, I would reccommend this product to a freind or anybody that is into photography!

So far so good. It's seems to hold a charge and do what the original manufacturer's battery did. I also purchased an after market charger and this battery fit fine into the charger so that added to it's pluses. As a back up battery, it's doing it's job.

Items were shipped and received in a timely manner. The Batteries perfomr as well as the Canon brand for 1/3 the price. Can't beat that with a stick!!
