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.

Update: I have now used 2 of these batteries for well more than a year. They are still doing an excellent job!

When you first get any new rechargable batteries, fully charge them before use. Run the batteries out 100% before charging again. Repeat this cycle 3 or 4 times in a row and your batteries won't develop a "memory" and will last longer.

I felt the original battery was pretty good in my 40D. I could take about 900 pictures with it. This replacement battery goes forever. Since I am still in learn mode, I tend to take multiple shots at various settings. The battery lasted a week, with 10% flash, constant picture review, constantly being left on....

Just get one. Besides, you should have a spare on hand anyways.

I bought two of these since they were rated at 2000mAh and the genuine Canon batteries were only rated at 1390mAh. Big mistake. My Canon batteries run a slideshow on my camera for almost 6 hours. That means these batteries ought to go for more than 8 hrs. Instead they last less than 4 hrs. Same test. And my Canon batteries are 5 years old. If my Canon batteries are still 1390mAh, then these ought to be rated at 925 mAh, definitely not 2000mAh.

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.

The battery holds a charge well but the physical size of this battery is just slightly smaller, (In Width) than the original and as such makes for a sloppy fit. I'm using this on a Canon ZR50. It hasn't fallen off, just isn't snug. I don't regret buying it.

I ordered two of these batteries about a month ago. I charged them both up (they came partially charged) and put them both into my battery grip on my Canon 5D. Since then I have shot about 500-1000 pics involving all kinds of AF and flash work and both batteries still show full charge.
Functionality is superb and the construction is identical to Canon's original BP-511A @ 1390 m-Ah.
Save some money and go to a more powerful battery by purchasing these.
I highly recommend this item.

This is the worst piece of crap I have ever bought. I have only used it about four times and it is already dead. Just goes to show there is no substitute for the genuine article. Please do not buy from this source.

I bought this battery and what I received was a battery not as pictured. Not only that the battery didn't fit my Canon Powershot G2 camera. I sent it back for another and low and behold they sent the same one again. Buyer beware!

Purchased this battery as a replacement to my original camcorder battery. First time I used it, following a full charge, it lasted for about 15 minutes. Recharged it and again it went for about 15-20 minutes. I'm not a heavy duty camcorder person so I don't really ask for alot from a battery. The battery that came with the unit lasted for at least an hour and a half before needing a charge. I STRONGLY recommend finding anothe battery supplier.

This battery is simply awesome. I purchased it as a backup battery for my 40D. I take lots of long exposures at night to create star trails. typically I'll take multiple 5 minute exposures over long periods. For this type of photography the Wasabi power replacement battery outperforms the original canon battery. The canon battery can normally take about 2 hours worth of continuous long exposures before the battery dies. The Wasabi replacement can easily go 3 hours. I'm finding that I'm now using this battery as my primary battery, and the canon original has been relegated to backup. All in all, this is a good deal. Cheaper and a better performer. I'm planning on picking up another one for my camera bag.
