5 Stars Decent for the money
Not as good as Canon, but for the money this will work great for a backup battery! I would say it lasts about 75% as long, and have not had any problems with it.

1 Star The marked voltage worries me a great deal
The Canon Xsi ships with, and is rated for, a 7.4v battery. This is listed as 7.2v on the box, the battery and on the Opteka website. I was told by a Marketplace Vendor that the 7.2v is a “misprint,” but there is no way of truly knowing and it’s enough to make me worry. I’d hate to damage a $$$$ camera over a $ battery. This one is going in the garbage and I’m going with the Canon Equivalent LP-E5 Battery which is marked with the correct information (7.4v!), has a solid reputation, and is currently selling for a better-than-amazon price on Diamondback Battery’s website.

5 Stars Better than I expected
Been using this battery now for over 3 months with my T1i.

Holds its charge a looong time. I haven’t timed it, but it feels at least twice as long as the standard battery.

…and you can’t beat the price.

Advice: if you’re looking to get an extra battery, get this one.

5 Stars Works just fine – excellent value
Having a new camera for taking pictures of museum artifacts (primarily), I needed spare batteries to “feed my flash.” Problem was that the OEM battery (Canon) was ~$70 USD each which would reduce the number of spares I could pack. Also, the OEM charger was AC only, so would not allow for recharging while in transit. Opteka to the rescue! Inexpensive batteries and a dual AC & DC charger fit my needs exactly. I used the batteries for all day shooting of museum aircraft (lots of flash usage) and they performed at least as well as the OEM battery. Recharging was quick also, being less than 90 minutes in the car, so I could always have charged batteries on hand. Excellent value and performance overall, highly recommended for the amateur photog, perhaps even for the pro. Didn’t try the Opteka batteries in the Canon wall-charger as I was the Opteka charger, so cannot comment on capability. I recommend the charger & battery combination anyway because of the DC car plug.

2 Stars got what you paid for
Fully charged it after some use of it already and seems as if it has the memory effect. The XSi camera’s battery icon shows it has at least half of the juice left before the camera stops working. Well, you trade 1/2 of the battery capacity for 3/4 of the cost. A good deal? In the shooting field, you may have twice the chance to have to change the battery at that monemt you wish you were not, like I was. Not sure if other 3rd party batteries more or less the same issue…..
