However, the period of time the battery is low is extremely small - probably a couple of hours at the very most, depending on the type of battery used. The battery current demands from todays advanced hearing aids... Read more

More info is needed to properly answer but I'll attempt to give a general idea of battery life and what impacts the battery's duration. The power draw required by the aid determines the life of the battery.... Read more

After the sticker is removed, let the battery sit about 5 minutes to fully activate before inserting into the hearing device. Since batteries were reformulated without mercury, it takes a little time for the paste inside to become fully... Read more
Christopher S. Frink, MS My experience with the battery life for Halo2 hearing aids is that they last about 7-10 days, based on full-time use (12+hours per day).

If you have... Read more
