I recently upgraded to KS10 aids, which have rechargeable batteries. But I’m keeping my KS7’s, which use 312 batteries for backup and for “risky” activity, like a river trip.
Would it hurt to keep a few batteries in the freezer for use when I use the KS7’s? Obviously, I would warm the batteries before use.
And first impressions on the KS10’s —
- Help me hear better (maybe because they have more aggressive amplification).
- Awkward to turn on/off. I miss the battery door.
I have a bag of 200+ expired batteries. The Costco fitter said they would not recycle them unless I taped over the vents in each battery. Anyone have other recycle options? They should be useful at least as scrap stainless steel.
