I usually get the 1000mAh batteries for the longer charge, but the smaller size of the 650mAh makes it a great choice to keep as a backup in your backpack/pocket (turn it off using the safety function when storing - not that I've ever had an issue forgetting to do this, but it makes sense!). Also makes your ego-C a little less noticeable to others which may be useful if you're not sure how friendly your surroundings are to vapor!
This battery is clearly not the passthru battery (which would have a USB port on it) so if you are looking for that feature, that product is also available on this site if you look. I have one passthru battery I bought for my ego-T years ago that I still get some use out of with my ego-C on rare occasion, but I have always preferred the non-passthru batteries.

The ego C is super dependable, charges overnight and lasts all day. Best of the many, many I've tried.

This battery is 1/2 smaller than the last four eGo-C batteries I've ordered and has no USB connection for charging.

This is not a PassThru battery and does not come with charger.
since previously i only used PassThru ego-T's I now need to buy a 8$ charger cable if I wish to do anything with this battery.
