Dual Battery Charger with 2 9V Batteries (Charger & 2 Batteries)

This is the best way to have the power you need to operate your TENS units.

I really like the product and the Company I deal with.

Great product with fast delivery and reasonable price.

I use my tens unit daily, the charger was a good purchase

There were no instruction with the charger so so not know if the red light goes out when the batteries are charged or how long to charge the batteries as you can damage the batteries by overcharging.
