6 Volt 4 Amp Hour Rechargeable Battery

I was looking for a rechargeable battery to power wireless microphones and these have been terrific. I can typically run two 2 hour productions without needing to recharge them.

I've only used it for a short while but so far I have nothing negative to say about it. It charged my Samsung Note 5 from very low (4%) to full in about an hour and there were still 3 lights remaining (about 75% capacity). It's a little heavier than I expected or would prefer but that's not too big a deal. The attached cords are a nice touch and there's also no need to turn it on. Just plug it into your device and it starts charging. Easy Peasy!

6 out let. good.

They said to remove the vent cover a half hour before use. I removed the cover and measured about a half volt. An hour later, 1.35 volts. Installed them, and now my vintage Luna Pro works perfectly! Great solution to replace an obsolete part!

Hard to believe a little flashlight like this could put out so much light and for a full hour. And also be rechargeable!

worked just like the product I replaced except uses a double A battery instead of a nine volt.

I replaced a noisy fan cooled amp with this one, and it is driving eight 70 Volt 5 Watt ceiling speakers in our church's overflow areas easily.

Great light but getting the rechargeable battery will make you use it so much more often.

This battery is everything I would expect out of a quality rechargeable battery.

Quality, well made and designed rechargeable battery.
