    • Replacement rechargeable 3.7volts
Color: Blue
This 2-pack set represents replacement batteries for a redlight Wand. They work well and hold charge for a long time. Up to this point i don't have any issue with them. I recommend them as good quality.

    • Not bad!
Color: Blue
The media could not be loaded. Upon arrival, these showed a very low charge, so much so that the person installing them in my solar panel was not confident they’d work, even when fully charged in the sun. But they not only have worked, they seem to be better than the original batteries that came inside the panel, as the lights they power now stay on all night, as opposed to the 4 hours they lasted previously. Not thrilled at what I had to spend 2 for replacement batteries, but happy that they’re working. ... show more

    • Good Strong Battery!
Color: Blue
Out of the small box and into one of my LED flashlights. It works! Right away got a strong bright white light. I was very surprised about that. Charging the battery is normal and no issues. So far I'm very happy with my purchase.
