TENS 7000 Official 12 Pack of Long Lasting 9-Volt Alkaline Batteries - 9 Volt Battery for TENS Unit - Pack of 12 All Purpose Batteries - Alkaline Battery for Everyday Use - 100% Durability Guaranteed

So far so good. The ones I am using are doing great. I have not had it long enough to review battery life. However they are fully charged and give great power

Great price! Works great, considering I paid over $17 for just ONE battery when I was in California

Good bargain, better than the blue ones they have

My daughter brought hers when she came to visit because I have so much pain in my arms and shoulders. It provided so much relief I ordered my own. I can't express how much help this is with the pain. It reduces it so much I can even lift my arms after. I've had no problems with it. Very dependable.

I was so glad to get these batteries. I was having some ankle pain and needed to replace my tens unit batteries for relief. Once I replaced them, my tens unit was back up and running so powerfully!

I bought 12 such batteries last November to replace batteries for smoke detectors. Please note that smoke detector batteries are for stand by in case of house power outage not for real alarm use. First battery worked only for a few months and 2nd one I installed last week and it worked only a few days. Do not buy these batteries; it waste of money!

surprised lasts as long as name brand or longer. great value

So far these 9 Volt batteries, used in a TENS Unit, are powerful enough to endure for days. Regular store bought 9 Volt battery is inadequate to operate a TENS Unit for more one day.

son justo las que necesito para mi maquina, duran bastante y las compré porque son de la misma marca que ya venia en mi tens 7000. las volveré a comprar cuando se me terminen
