Best selling hearing aid battery in the US. Rayovac sells twice as many as any other brand. Surveys show it's recommended by more independent Audiologists than any other.


a) Most hearing aid batteries are like your supermarket "own label" baked beans.The supplier sources budget products from manufacturers (who they don't divulge) for the best price. Manufacturer may change from time to time. None of Realtone, Triton, Hear Clear or Widex are battery manufacturers. They ALL simply label a battery from an unspecified origin.

In my experience the life of these "own label" batteries vary considerably from batch to batch. Over 4 weeks I have had a Rayovac one in one ear & one of these "own label" ones in the other. alternating ears each change. In every case the Rayovac outlasted the other by more than 10% sometimes more than 25%.

b) Other TM batteries with claims of the great origin fail to mention they are budget label ones. Powerone is the budget label division of Varta batteries.

c) UK NHS Govt tests of ten manufactures show the Rayovac to last longer than other 312 type product they tested that is sold on TM.

d) Beware of Chinese batteries with safety and explosion issues. Zenipower had a massive recalls of batteries globally in 2016 2017

RAYOVAC is the battery division of Spectrum Corporation RAYOVAC "EXTRA" label ones are the top of the range battery they currently produce. Longer lasting than their Peak, Ultra or their other budget models

Rayovac products lead the world in battery power & innovation. In April 2017 it announced the world's longest lasting 312 battery. Google "World's Longest-Lasting hearing" for details
