No good for a TENS unit,
Verified Purchase(What's this?)
This review is from: Tenergy TN141 2 Bay 9V Smart Charger with 4 pcs Centura Low Self-discharge 9V NiMH Rechargeable Batteries (Electronics)
I use these in a TENS unit and I barely get about 30 minutes. I get about 3 hours out of basic duracel battey. Not a satisfied customer.
