Should I try the battery trial pack?
We would recommend you stay with one brand of battery for the first six to nine months of using a new hearing aid before trying out other brands of batteries.
During the first few months of using your hearing aid, the program (or settings) will most likely be adjusted several times. Each time the settings are adjusted the power requirements change, which makes it difficult to compare battery performance during this period.
Once the adjustments to the settings become less frequent, you may wish to try the Hearing Aid Battery Trial Pack to see if another brand of battery offers better performance.
