Yes. With a regular, daily training of 15 min. the batteries should last approx. 4-6 weeks, depending on environmental conditions (temperature, time

between training sessions etc.). If the batteries are discharged earlier, the cause is either a longer/ more frequent training session or the

batteries were partially discharged from the beginning. Please make sure to use alkaline batteries within the printed expiry date. In very rare

cases, there is a short circuit, the battery becomes warm, and the device must then be checked/repaired by MediTECH.
