What to know before buying

Listing details to confirm

The listing has contradictory and inconsistent pack details: the title says 80 Rayovac Extra batteries plus 8 Udivita, while a feature says 80 Rayovac batteries and 8 Udivita in 10+1 blisters of 8. Other details call this an 80-battery pack, so the exact quantity and brand split are unconfirmed. The battery-type field says “Other Than Listed” while feature text calls the chemistry zinc air. Confirm the selected listing's pack and chemistry before purchase. The stated 9% longer life and up to 20% increased lifetime claims use different comparisons, and their conditions are not explained.

Who is it for?

A good fit for

People whose hearing aids use Size 13 batteries and who prefer buying a larger supply.

Less suited to

People who need rechargeable cells or a clearly confirmed brand-specific pack quantity.
