About Power One Size 312 Hearing Aid Batteries (80 Batteries)
Overall Feedback:
76% positive
64% appreciated the broad compatibility, although 36% found it didn't fit their model
The battery I received was not as per my order.
After the batteries came with brown tabs, my battery life has been terrible.
My battery level drops to 70% or less on the same day I put them.
On my most recent order, there is a sticky residue remaining on the battery surface which blocks electrical contact in my hearing aid.
65% praised the long-lasting battery life, while 35% experienced shorter duration
If I use Bluetooth for phone calls, the battery life lasts less than a day, but if I turn it off, it lasts around 2 days.
My battery level drops to 70% or less on the same day, and within 2 days it is down to 50%. Most brands I have used last at least 6 days.
The battery life is poor as it only lasts for 2 days and sometimes only one. I changed the battery 2 hours ago and it is already going dead.
65% liked the ease of recharging
The batteries may appear dead but they may only be playing possum. Don't discard them at that point as they may come back to life and provide an unexpectedly long period of continuing service when reinstalled.
67% liked the durable battery construction, but 33% experienced premature wear
I retrieved a previously discarded battery and put it in my hearing aid just to see what would happen. Four days later, it is still operating above 50%, proving its durability for longer use.
I am dissatisfied with the durability of the hearing aid batteries. The battery level drops significantly within a short period of time.
I have noticed that silver batteries have better battery life than brown tabbed batteries.
Most of the time, the batteries last for 2 days, but sometimes only for 1 day.
