    Fit perfectly into my rechargable spotlight (uses 6V 55W quartz lamp). The battery arrived with enough charge to fully energize the light. I’m not sure about the battery’s longevity, but I will edit my review if it fails to perform in that regard.

    This battery came in on time, was packed well, and works well. The in system tester gave it a green light. It is nice to be able to get something good and not have to worry about it.
