Even though they don't last that long (a year or so), both capacity and current capability are pretty good.

Cheap Low internal resistance (less than 30 ohms) Both cells have very similar capacity Handles 10 amp load without much hassle
CONS
Capacity is not 2100mah, nor 1600mah as fasttech says. Bottoms seem to be attached loosely, so might fall off.
I needed high drain 18500 cells for certain LED light project. Checked online, these seemed to be the best ones, since had measured capacity of 1600mAh. Ordered them, they arrived timely (sent from US... (read full review)
