problem with the theory and the reality… is the reality… hmmmm someone famous said that…
if volume of background noise causes increased battery usage
if heat decreases battery life
if moisture decreases battery life
the variables are HUGE for each user…
that said averages are averages… and give or take 1/5 a day or even a day… Hell you can hear better then you could before you put them on… so for 10 bucks buy 40 batteries…
The price of batteries vs the premium aids is noise
discounted premium aids justifies buying your own batteries on the net or at discount locations
If batteries cost the same then clearly buying the ones that get the individual more time and last longer on the shelf…
How many folks worrying about batteries have tried 15 brands of gasoline to see which gets better mileage? and then done a price value analysis and then only buy the gas that gets them the best…
We all live on tight budgets… but that said… one less meal out a month will cover lots of extra batteries… even if it is a fast food meal…
Generic brand mayonnaise will pay for lots of extra batteries vs branded.
for those without premium aids… and are struggling for the longest battery life from a monetary vs theoretical basis… then I suspect they are reading this at a library vs at an internet connection from home…
I don’t buy 1800 dollar glasses… I pay a couple of hundred from costco… I could buy costco 150 dollar eye glasses… but want the added features of the premium price…
But I buy them where they are cheapest… Some folks have to get them from the VA and hence no progressive lenses and perhaps no transition lenses…
Lots of folks who need hearing aids don’t wear them not because they cannot afford them or do not want to afford them but because they just do not want to…
some folks feel the same way about glasses…
40 bucks a year for batteries for me is ell worth scrimping on something else to be able to hear better then I can without the aids…
YMMV
