SAV : choice of batteries

  • Did I buy the right batteries?
It is absolutely necessary to use 1.5 V batteries for electrostimulation devices.

Prefer alkaline batteries, which are much more reliable than generic batteries.
  • Can I use rechargeable batteries?

Yes, but you have to be careful about the power of the batteries. Rechargeable batteries are often 1.2V, whereas you need 1.5V batteries for Sport-Elec devices. With unsuitable 1.2V batteries, your device may not work and the information on the screen will remain blinking.
So beware of sub-brands that are sometimes not of this quality.
