I have Kirkland hearing aid(s) that charge by plugging the case into a wall socket. I bought a detachable battery to ensure I would have power to charge the aids at my cabin where there is no power. This battery is on its last legs, only holding sufficient power to ensure one charge, plus a few additional hours. This battery snaps onto the base of the charger and I have observed that it looks similar to the base of a non Kirkland unit owned by my friend. Do any of you fine folks know if these rechargeable battery packs are interchangeable? Alternately, dose anyone make a
generic unit? Thanks in advance for any insight into this.
