What to know before buying
- The product title identifies Energizer batteries with PowerSeal, but the brand fields identify Udivita. The listing also describes the cells as suitable for both hearing aids and headphones or earphones, so confirm the intended device and battery size before purchase. The claimed four-year charge retention applies to storage in the original packaging, and the leak-protection wording is a manufacturer claim.

- Buyers looking for blister packs of eight and who have confirmed that size 312 matches their device.

The supplied evidence contains aggregate ratings but no written customer feedback, so it cannot show what buyers liked or disliked or why. The overall rating profile includes both five-star and lower ratings, which is limited evidence for judging consistency. For buyers, the listed size, voltage and blister-pack format are more actionable checks than the ratings alone.
