I’ve been told that digital hearing aids do not perform at full capacity (using throw away batteries) toward the end of battery life. Now back when I wore Starkey analog HA’s that didn’t seem to be a problem, since my Starkey aids seem to function fine up until battery died. Several years ago when I switched to Widex I did notice a decline in HA performance during the last few hours - or even day before my size 13 or 675 batteries failed. On the plus side (at least with the Widex aid) I always received a “warning tone” an hour or so before my battery died.
In any case I was wondering if rechargeable batteries also have an impact on HA’s, when they approach the end of their charge. So if a battery charge lasts say 18 hours, could a HA user notice a decline in HA performance when battery reaches 16, 17, or 18 hours of use? I’ve also read on HT that “heat” can impact the life of a battery and for users who live in warm weather, battery life (or should I say strength) will decline faster in warm weather than cooler weather.
Putting aside the pluses and minuses of rechargeable battery versus throw away, is it true then a person using rechargeable batteries will see a decline in HA performance every evening as their battery weakens, where someone using a throwaway battery will just notice power decline once a week, or longer if bigger battery is used?
