Testing hearingaid batteries

Different hearingaids use different sizes of battery, they also consume battery power at different rates. A battery may last a week in one aid, but only 3 days in another.

I’ve written before about testing a new hearingaid and making a decision whether you want to buy it – it’s also a good idea to test the batteries to find out how long they will last. During your hearingaid’s trial period, use the same battery until it runs out – did it last long enough? How much are you going to have to spend each week on batteries? The price of a packet is tiny compared to the price of the aids themselves but the weekly cost will mount up over the years.
