Involvement:General (knows how to use it) - Ownership:1 week to 1 month

Pros:
Very long lasting. They fit my flashlights very well. Protection card at bottom of cell works very well keeps from over charging and low voltage from ruining the cell. Great product well constructed.
Cons:
None i know of
Other:
Seems to last as long as the sku 20392 red and black batterys at about $1.25 USD per cell less cost.I have had no problems with any of them so far. Color is a bit drab (grey)but who sees them inside the light anyway. I have used in both of my flashlights for more than one hour on high beam.
Bottomline:
I bought them to my flashlight (SKU 16179) and they are working great so far (around 1 months already). I use it on irregular basis but never found it not working even after a month staying in the drawer. It's a great deal! Do not buy other cells. They are just great!
