Customer Reviews
This battery blew out two of my portable lamps because the wires were installed incorrectly. They are reversed. The photo shows a correctly built battery compared to the one that I got from here that the wires are backwards. Unfortunately, I didn't realize the issue soon enough.
With a little extra work they fit using the original battery connection
I will have to re engineer with old battery. Will not charge on my device.
Easy to change out in my light and works great
I LIKE THE BATTERY BUT IT DONT WORK INTO MY ALARM SYSTEM AND I CANNOT USE IT THANKS
