what is it about hearing aids that burn batteries faster
Unused hearing aid batteries lose about 3% of their capacity every year. Batteries do fade; this is true across all battery brands. After year 4 the battery should have about 85-88% of its original capacity. Perforations will not occur. While the steel we use is thin, it has a lot of support underneath.
We have many different batteries and alternatives for your hearing aids. The typical life span of a regularly-used hearing aid battery is short, sometimes only between 5 and 10 days. So itâs best to stock up on the size you need when you spot a good deal from a trustworthy battery supplier.
