To go with my new Canon Digital Rebel T2i, I looked around for a third-party LP-E8 battery. Yes I know the argument--"why would you put $4/$8/$10 battery in a $800 camera, it's worth it for the peace of mind to go with the genuine Canon battery," etc. Well having been using digital cameras and DSLRs for well near 10 years now, and having used plenty of third-party batteries (including "name brands" like SterlingTek and other no-name ones), I don't have any qualms about using third-party batteries. They work just as well for a fraction of the cost. Really, when was the last time you've heard of a digital camera exploding or catching on fire because of the third-party batteries?

I have a Power2000 brand LP-E5 equivalent battery that I've been using in my Digital Rebel XSi for the past two years with great results, so I wanted to get the same brand for the T2i (LP-E8). I bought it through Amazon.com's Marketplace, from a vendor called TheMemStore. They shipped it promptly, and I had it a few days later.

The battery charges fine in the T2i-supplied battery charger, and works fine in the camera. It is rated for 1,500mah capacity as opposed to the genuine Canon's 1,120mah, so in theory it should give you approx. 35% more shots per charge. As I tend to recharge the batteries whenever I return home, and not necessarily let the batteries go until they are fully discharged, I haven't really noticed a difference yet--but it certainly seems to last just as long as the Canon battery that came with the camera. The T2i seems to eat up battery power rather quickly while shooting video, so I may end up getting another one for a full day's shooting/recording. One difference between the Power2000 battery and the Canon OEM battery is the rated voltage: 7.4V for the Power2000 and 7.2V for the Canon battery. A cursory web search indicates that this is within acceptable fluctation range for the battery.

I've uploaded a couple of pictures of the battery package and the battery itself. Notice the package states 7.2V, but the battery itself states 7.4V (same as the item description).

Overall I'm pretty happy with this battery--a great value for 1/5 of the Canon battery's cost.

Owned this for about two weeks and its been a great battery. on its first two charges its held them longer than the standard Canon battery, and for this price, thats amazing. I'm just hoping it continues to perform this well for a while. To be honest though, at this price it doesn't need to.

2.0 out of 5 stars Voltage differences ... beware!!, October 26, 2010

On one of the submitted photos, the packaging indicates 7.2 volts, which is correct per Canon, but the battery photo list 7.4 volts -- which is incorrect.

What potential problems will that increased voltage present?

I was considering this battery at one time, and just took a closer look. I will not buy it now.

Amazon forces one to add a rating, so I'll muster up two-stars since they can't even match the OEM voltage.

==== SOME EXCELLENT BATTERY INFO I'M QUOTING FROM ROBERT MALECKI ...

Robert S. Malecki says:

"Lithium polymer battery packs are labeled with their nominal voltage rating. Each a "cell" is the smallest voltage denomination for a lithium battery. Each cell for a Lithium Polymer battery is rated at 3.7 volts at nominal charge. At full charge, each "cell" will be at 4.2 volts.

The power 2000 uses the cheaper lithium polymer batteries in a 2 "cell" configuration. this basically means that there are 2 3.7 volt "cells" in series. At full charge the correct voltage reading should be close to 8.4 volts. If you let the battery level get below 3.1 volts per cell, then the *battery dies* and cannot take charge again.

Because the Canon battery is rated at 7.2 volts at nominal, then i would suspect that they are using the lithium iron phosphate (aka. LiFePo or A123) since they are rated at 3.6 volts (2 cells = 7.2 Volts) at full charge per "cell" LiFePo batteries are ...

... more durable, have a longer charge cycle and can charge faster. [Robert is referring to the OEM battery here]

It would be interesting to see a data sheet on the canon battery. Both batteries have about the same charge density but if in fact the canon charger is designed to charge LiFePo batteries, it might be a bit risky to charge the LiPoly battery with the canon charger. Hope that helps"
