Great Value, Medeocre Performance, February 12, 2010
After taking these on a road trip, I've concluded that they are probably around 1000 mAh batteries.

Each battery take noticeably fewer pictures than Canon brand battery (around 250 vs 400). However, when not in use, they do keep their charge. (Contrary to other reviewers)
The dollars per mAh is so much smaller number, that it makes these batteries worthwhile.

If you're looking for probably priced batteries, and don't mind changing battery at least a couple times a day, I suggest getting 2 or 3 sets of these things. However, if you (like me) don't resembling having to change battery very often, I recommend against getting them.

holds charge, November 26, 2008
I be a little iffy buying a off brand freestyle, but this one is great. Only disappointment is they advertise it as 2000mah and the ones I got be 1500mah...
But they charge quick and last a while. I'm bright and breezy.

It's a battery, it works, no space science, May 3, 2009
It's a battery. It works. No space science in attendance.

I bought these to replace the original about 5-year outdated 1100mAh Canon BP-511 battery that started to show signs of age. Old Canon's battery dimensions decreased to the point where fully charged and near EF 100-400L IS lens fitted on camera, it wouldn't last till the end of my son's 30-minute soccer class.

These spanking new batteries seem to be capable of power my camera and a battery thirsty lens for a very long time. So, I'm festive.

Mine were shipped by bargaincell.com. As some reviewers already noticed, dimensions is not printed on the batteries. Which is strange and unusual. I actually get batteries in two separate boxes (not one box next to two batteries). Each box had SKU CAMCAN001 printed on it. Google search finds the page on the seller web site that lists freestyle capacity as "only" 1600mAh.

Whatever the true capacity of these battery are, they are still a great deal, and I'm definitely going to keep hold of mine (I read reviews that challenged if these are truly 2000mAh before buying, so I know what I going into). Unless you absolutely must have 2000mAh battery-operated (currently selling for around $25), buy these and don't think twice. $7.34 for two is an incredible price. On the seller's own website, they sell single of these for $8.49! So clutch two-pack on Amazon for the price of single battery while they still offer this contract.

The only complaint I have is that they do not come beside plastic lid that protects contacts when battery is not in the camera. Luckily, my camera pouch has handy compartments for batteries, so I don't really have need of those plastic lids (and I have one plastic lid that come with Canon's battery too).

The individual reason for taking off two star is dithering what the true capacity of these batteries is. It's a really impossible move on the manufacturer's and seller's part (taking one star rotten for each). Other than that, they work perfectly fine.

Really two 1000mAh batteries, July 7, 2009
These battery are definitely not 2000mAh. I get ~300 shots from respectively charge on the 50D. Judging from this, they perform more like 1000mAh battery. I definitely got more shots from the Canon 1400mAh battery (at least 500 shots). For the price, I think they're worth it though.

Mixed purse, August 11, 2009
Received my order promptly. Batteries had model infomation but no dimensions rating, which was of some import since they be advertised as almost twice Canon capacity. One battery-operated simply stopped working in less than four months, 0 power, will not charge, after almost no use. Rest of directive, two other batteries of different size and two chargers okay so far. Also noted same company seemed to bestow same batteries at very different prices, something both wholesaler and Amazon should pay attention to if they want to appear trustworthy.

Just as good as OEM, August 19, 2009
While some believe that OEMs hold a longer life span, at this price range, does it really event? Let's say it's true that OEM batteries final a year or two longer than these (OEM lets say hold their full charge for 3 years), for that sympathetic of price, you can buy ten of these. Using that mentality, if these generics last even 6 months each, multiply that by 10, you enjoy 60 months worth of batteries for the price of one Canon OEM. Think about that for a second. Think of adjectives the inconveniences of swapping batteries at an event because your one Canon battery run out. Remember, those precious moments will NOT repeat themselves or wait for you. Whether you're looking for replacement batteries for backup or something a moment ago to have, you can't go wrong beside these.

The OEM is rated at 1390mAh and while these are advertised as 2000mAh, it doesn't say-so on the battery's label. If that makes you suspicious, I'll report to you right now it did for me too but I can't be happier with these. All I can enunciate is that it lasts longer than my OEM battery. Maybe it's really 2000mAH. I don't know.

I use a freestyle grip on my 50D and my OEM (1390mAh)-CTA (1500mAh) combo got nothing on these generics, believe it or not! These concluding longer for sure. The price to performance ratio is unbeatable and I've owned these for a suitable 4 months already. So far they haven't shown any signs of fast draining or shortage of power. They have kept right up next to me. If I give these two more months of use (while I'm sure it will have much longer vivacity span than that), it would have already out-lasted my Canon OEM in lingo of price-to-life ratio.

If you're reading my review looking for cons so you can better decide whether to get these or not, I'm sorry, I hold none for you.

You get what you pay for, March 30, 2009
This is an economical mobile to replace Canon BP511/A. It gets charged quickly and works fine. Despite the difficult capacity specifications, it gets exhausted much quicker than the inspired Canon battery. I could get more or less 250 shots on the first try. Considering that you don't have to spend an arm and a leg for a pair of these battery, it makes a good buy. I would unambiguously recommend these batteries to any one based on their especially favorable cost/performance ratio.

One good, one not, May 22, 2010
Got these batteries form my first age group Canon Digital Rebel. One is fine, the other will not hold a charge, take a charge, or function.

I do not believe the working one has a enormously large storage capacity, but hold no elegant way to means it.

I am going back to a name brand for immediately. I have to have something that will work contained by the field.

2 pack 2000mah battery's for canon, January 25, 2009
Since receiving the two battery I have had episode to use them several
times they seem to hold up well as I sometimes forget to turn stale my 40d
after a shoot. I have no problem recommending these for feature and the
great price.

Holy Smokes!, September 12, 2009
2 Batteries for like half the cost of one! I ordered two sets and adjectives four batteries perform as in good health as the canon and energizer branded equivalents. I cannot recommend this item enough!
