Hearing aid batteries

6 02 2007

I’ve been changing the batteries on both aids every hour or two for the last couple of days. Arrrghhhh! I haven’t had this problem before and it’s really annoying, especially as I was in a 5 hour meeting 😦 The batteries don’t die out slowly as with analogue aids so you don’t have the warning of sounds dying away, and my new aids don’t beep when the battery needs changing. The aids just go dead. Just like that. Pffftttttt!

A colleague is an expert on hearing aids so I asked for advice. It appears the batteries I have are useless – Power One P675 – and these are supplied by my hearing aid clinic! and my other batteries ZeniPower A675 are allegedly suspect.

I’ve been advised to hang the aids up at night to dry out, with the battery compartments open and batteries out. Just hang them over the lid of the box they came in, or an eggcup, or something similar.

Gently wipe the battery compartment contacts (and audio direct input shoe contacts, if using shoes) with a cotton wool earbud or a matchstick with tissue wrapped around it.

Whilst on this subject, thick walled tubing is better to have as you don’t really get much condensation, as you do with the thinner walled tubing.

Fingers crossed, this will sort itself out without a trip to the hearing aid clinic. It’s that time of year, overhauls galore…

Unfortunately, batteries and hearing aids can be a complex thing.
Two users of the very same device can experience different results using the same batch of batteries. This is even more so with implants.
The best you can do really is get yourself a pack of each batteries available (currently NHS should provide you with PowerOne, ZeniPower and Rayovacs) and test them each in similar conditions. Then you can decide which one is better suited for you.
Also note that your processor can be the culprit, not necessarily the batteries. If after extensive tests, no batteries last more than a couple of hours, something might be wrong with the processor, try to have it checked.

Great blog by the way!

Funny how in one ear it gives you an annoying beeping sound every 5 sec and the other ear it drops dead.
