PowerOne ACCU plus Size 312 Rechargeable Hearing Aid Batteries

These batteries are designed to work with a PowerOne Pocket or Pen Charger. These DO NOT WORK with Oticon Hearing Aids or Z Power Chargers or with many built-in hearing aid chargers. If you have not used this hearing aid battery in your device before, please check with your audiologist or device manufacturer. NiMH Rechargeable Batteries have significantly less capacity than a disposable. You may need more than one battery to last an entire day. Please purchase accordingly. These items are not returnable or refundable after opening! Thank you.
