Too early to tell if these batteries give the same performance as the ones we've had from other companies. However, receiving notice that the same type of batteries could blow up (fortunately, ours have a different use before date) is very alarming. This was forwarded to us to check our expiration dates:Medical safety alertAll ZeniPower mercury-free hearing aid batteries – low risk of batteries exploding during use or if depletedManufactured by Zhuhai Zhi Li Battery Co Ltd – stop using batteries with certain best before dates (MDA/2016/003)Device detailsOnly batteries with best before dates of ’08-2018’ and ‘09-2018’ are affected.If you purchased these batteries from NHS Supply Chain, their codes (NPC) are given below:NPC (England only) Manufacturer product code Description BrandGHD3582 A675P MF R44 zinc air size 675 for cochlear implants ZeniPowerGHD3583 A675 MF R44 zinc air size 675 ZeniPowerGHD3584 A13 MF R48 zinc air size 13 ZeniPowerGHD3585 A312 MF R41 zinc air size 312 ZeniPowerGHD3586 A10 MF R70 zinc air size 10 ZeniPowerSince 13 January 2016, NHS Supply Chain has received new supplies of batteries, which do not exhibit this problem.Problem / backgroundThe problem is caused by excessive gassing, as the zinc electrode reacts with the electrolyte to generate hydrogen.
