About Rayovac Size 312 Extra Advanced Mercury Free Hearing Aid Batteries (80 Batteries)
Overall Feedback:
94% positive
77% appreciated the broad compatibility
I faced issues with another brand of batteries which caused strange issues with my hearing aids. However, I have switched to this brand and now only use this brand.
84% praised the long-lasting battery life, while 16% experienced shorter duration
The battery life of Rayovac batteries lasts 5-6 days, which is an improvement from other brands.
Rayovac Extra batteries last for 4.5 to 5 days, while other brands last for 6 to 8 days.
In the first package, all batteries lasted for 7 days, but in our current package, 2 batteries have already gone dead after half an hour.
85% liked the durable battery construction
The batteries work as well and last as long as any others I've tried over the years.
The batteries arrived fresh with a use by date of Feb 2025.
90% appreciated the easy-to-use design
My audiologist told me that this type of battery gets its energy from the air and it is important to leave the tabs off for at least one minute before using. This shows that the battery charger has a user-friendly design.
I have found that the Ray-o-vacs have been very predictable in terms of battery life, lasting 6 days with each change.
