These hearing aid batteries are replacement batteries for size 312 hearing aid batteries. These hearing aid batteries are 1.45 volts. There are 60 batteries total per box and they have a 3 year shelf life, but when activated (tab is removed) shelf life becomes much shorter.
Batteries are a consistent quality at a reasonable price.
I have been ordering size 312 hearing aid batteries from Battery Mart for years. The batteries are very well priced and work as one would expect. Ordering from Battery Mart is extremely easy and shipping is instantaneous. Great company, excellent batteries and ordering is a walk in the park on a sunny day!
Fair price. Long shelf life. Arrived as scheduled.
I wish you offered mallories in this size, but these work OK and shipping is fine. I'll stay your customer
These batteries fit my wife's hearing aids perfectly. They last as long as the ones she was getting from the hearing aid company.
