I got a couple of these a few weeks back from

After a couple of weeks of testing, I’ve concluded that I’ll never buy a Canon branded LP-E6 battery again. 7D and 5D owners can now rejoice.
Yes they last just as long as the real thing.
Yes they are chipped and will tell you the battery level.
Yes they are more than 3 times cheaper then the real thing.
What more is there to say?

Edit 24/08/10: I forgot to mention they also charge fine in the original Canon chargers.

I got them of if you’re wondering where I got them from but it looks like the same battery has flooded the market as can be seen by the multitude of eBay sellers around the world selling the same looking battery.
