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
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
