Buy Cheap 2000mAh BP-511 / BP-512 Replacement Battery for Canon EOS 10D, 20D, 30D, 40D, 5D, D30, D60, Rebel, Optura 100MC, 200MC, Pi, Xi, PowerShot G2, G3, G5, G6, Pro 1, 90 IS, ZR40, ZR45MC, ZR50MC, ZR60, ZR65MC, ZR70MC, ZR80, ZR85, ZR90 From Here Now!This is a 2000mAh high capacity replacement battery. The higher the mAh rating, the more power a battery can store and the longer it will last per charge. It contains premium Japanese grade A battery cells and is guaranteed to outperform the Canon original battery. It is CE certified and built to meet or exceed the OEM specification. It is guaranteed to safely power all cameras and camcorders that use the BP-511, BP-511A, or BP-512 batteries. The lithium ion chemistry of this battery makes it 100% memory free. Unlike Nickel-Cadmium (Ni-Cad) batteries, lithium ion batteries don't have a "memory effect" which shortens their capacity. They can be partially charged and/or discharged without worry of shortened battery life. Unlike most aftermarket power supplies, our batteries have undergone rigorous cell cycle testing before leaving our factory. If a battery does not pass our benchmark testing for superior performance, it will be eliminated from the production line. This guarantees the best possible quality in all our batteries and virtually eliminates the chance of a product being shipped dead on arrival. Includes a 3-year warranty. Because we use premium Japanese cells and the highest quality components, we are confident that the battery will last the duration of the warranty and beyond. However, in the rare case where you experience a problem with the battery within the warranty period, it will be replaced promptly. Specs: 7.4V, 2000mAh, Rechargeable Li-Ion; Compatibility: G1, G2, G3, G5, G6, Pro 1, Pro 90IS, EOS 5D, 10D, 20D, 30D, 40D, Digital Rebel, D30, D60, ZR10, 20, 25MC, 30MC, 40, 45MC, 50MC, 60, 65MC, 70MC, 80, 85, 90, Optura 10, 20, 100MC, 200MC, Xi, Pi.

"excellent battery" 2010-02-05
By Bart J. Schuck
Admittedly i was relunctant to buy anything that is coming directly from a seller. And then when i read reviews about other after-market batteries, I was even more leary. However, this product is very good. I took it on the field of a football game and shot over 800 pics, many in burst mode to catch the action (Canon 20D). I kept checking the battery life expecting I'd have to change it. I was very pleasantly surprised that it lasted the whole event. However, when it did start to lose power, it went from full to empty without anything in between--kind of like me--I either have energy or i don't. :)

Service was on greased rails. I never have had service or quality problems with Amazon, including this purchase. I've used generic batteries for my camera in the past, and they are worth the lower cost.

"Great Product" 2009-11-09
By RayRay
The KINAMAX battery uses a Japanese Cell so the life of the battery is longer and you get the full advertised power instead of the fake batteries that advertise one amount but do not come close to it.
Great price great battery, what else can you say?

"Great Storage Capacity For The Price" 2009-10-18
By Scott T. Spence (Kennewick, WA U.S.A.)
Seriously, who writes a review of a battery? After all, it's just a battery. Not necessarily so. The Canon battery costs more and has less storage capacity. When purchasing batteries, be sure to look at the storage capacity of the batteries in question. The storage capacity of batteries this size is expressed in mAh (milli ampere hours). The higher the mAh number, the more energy the battery stores. This battery has almost 44% more storage capacity than the Canon battery. Want to compare more batteries? Try this - divide the cost of the battery by the number of mAh. For this battery, $24.67 divided by 2000 (mAh) equals $.0123 per mAh. For the Canon battery, $37.59 divided by 1390 (mAh) equals $.027 per mAh. By the way, I use this battery in my Canon EOS-40D.

"WOW!!!" 2009-05-22
By Dwight Schrute (Moscow, ID USA)
I purchased this battery for my Canon 40D, and I have to tell you, this is the best battery deal out there. The factory battery is a respectable 1390mAh, but this battery is 2000mAh. I took almost a thousand pictures with it last weekend at a car show and still had battery left. That's impressive. Two of these are all you could ever need. My only gripe is that it's a little loose in my charger, it still works though. Go get a couple of these things.
