Great battery but not fit in outdoor solar led light

Note there is a difference between the button top and the flat top 18500. The button top will not fit in solar led lights from Home Depot or Lowes. Flat top required.

Good battery
January 26, 2021
I bought two of these batteries as replacement batteries for my old Wolf-Eyes Raider flashlight. They work, but connection is hit or miss as these are button top and the original batteries are flat top. I am hoping a slight mod will correct this. Battery is fine though.

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.

Had to return due to the item the batteries were to have serviced was not available.

The experience with you was very good however.
