Summary: This is a decent battery. It does not pack a stellar charge but it's okay. The quality of these batteries varies, even within the same batch. I don't know what the spec is, but you should be able to get at least 150 charge cycles out of one, and maybe a lot more.
Summary: the battery i recieved was not the gen canon battery BUT when i pointed this out they were quick to offer a full refund and sent a ups return so even the shipping would be covered that said i have kept it anyway as a back up not sure if it holds the charge for the same amount of time, the canon...
Summary: They are the right battery for replacement. Contrary to what I've read the battery meter do work in the camera. My only concern is that on the two I got a bad one. I didn't had to use the second battery for some time and I started to need it.
One battery works, the second battery doesn't fit.

Summary: One of the batteries works fine and slides perfectly into the battery slot on my T2i. The second battery is damaged at the connectors (the battery case has partially expanded), resulting in the battery not engaging properly with the camera.
Summary: The battery came really quickly after it was ordered, but came in just a plain brown envelope with my name hand written on it, and the battery itself was just vacuum packed in a piece of plastic with nothing but the plastic battery holder for protection.
Excerpt: Battery chargers are available plenty in the market but very few offers satisfactory performance. It is necessary to depend on a high-performing battery charger to enjoy seamless charging solutions. Canon LP-E8 Battery Charger is renowned for its unique features and advanced technology.
