Medical Device Alert - ZeniPower mercury-free hearing aid batteries

battery pic

County Durham and Darlington NHS Foundation has been alerted to a potential risk with ZeniPower mercury-free hearing aid batteries.

While we have not issued any hearing aids with this type of battery over the past 12 months, some patients may still have batteries issued before this time.

The national alert states there is a low risk of the batteries exploding during use or if depleted.

Please check your batteries and do not use batteries with a best before date of '08-2018' and '09-2018'. This date is on the outer blister packaging. Please see the attached photo.

If you do find you have these batteries and have been issued them by County Durham and Darlington NHS Foundation Trust please return them to our audiology service.

If you were supplied these from a different provider then please return them as appropriate to that provider.

'I have to compliment everyone on their pleasant persona and their expertise and knowledge. By the end of the 5 days, I did not feel as though I had been in a hospital ward and was very relaxed.'
