I probably have a dozen of these by now, having bought thrice from the same seller (who also gets 5 stars for great communication, customer service and quick shipping). My use has been with slow drain devices and they have lasted a long time. Charging time is excellent.

I use these in a TENS unit "a electrical pain stimulator for pain management". They work very well. Lasts longer than any other 9v I have Found. I have to use these for whole days at a time and the high capacity really helps with how many times I have to change the battery and can carry less of them with me. I have been using them for months and they seem the same as when I 1st got them. I'd recommend them to anyone who needs a good long lasting 9v.

Now I got them when they were a lot cheaper, send the Seller a E-mail, maybe you can as well.
