I didn’t see any recent topics on these, so if there is one, please point me there.
I have Oticon OPN hearing aids - the original ones (and yes, I TRIED to get Oticon to replace them with the S or whatever when Z-Power went belly up. Oticon wasn’t interested). And I’ve been using the Z-Power rechargeables. My audiologist knew they were going away and got me some spares, so I’ve been OK for the last couple years. But, one of the problems with these batteries has ALWAYS been that the FIRST TIME they run down all the way, they NEVER work as well again.
A brand new pair of Z-Power rechargeables would last around 18 hours. After the first run-down they’d immediately drop to 14, which made them much more prone to running dead and after the next time they’d be down to around 12 hours. They’d stay there and slowly deteriorate, eventually being good for around 10-12 hours. I’ve never had a set last more than about 6-8 months.
I’ve exhausted my supply of spare Z-power batteries, and since they’re now going for at least $60 each, buying more isn’t going to happen.
Is there a viable, cost-effective alternative for rechargeable 312 batteries that will charge in the hearing aid? If I’m going to have to pull them out and put them in EVERY DAY I may as well go back to non-rechargeable batteries. Power One SHOWS rechargeable 312 batteries, but will they work in the Z-Power charger?
If not, I go back to regular batteries and put the Z-power charger on the wall to remind me when it comes time to replace these Oticons.
