I would recommend this item to a friend.

Batteries are too short.
September 28, 2015
Everything was handled perfectly, however the batteries I ordered turned out to be too short. You were my only hope of finding batteries for my outdoor solar light. What I need is: 1850, 3.7 volt, 600 mAh and you had the closest thing but they still wont work because they are too short.
