80x 10 Rayovac Extra hearing aid batteries

This pack contains 80 Rayovac Extra hearing aid batteries in size 10, divided into ten blisters containing 8 batteries each. These are non-rechargeable zinc-air batteries with a nominal voltage of 1.45 V. The colour code for size 10 is yellow; the corresponding IEC designation is PR70.

The battery has a diameter of 5.8 mm and a height of 3.6 mm. It is intended for hearing aids with replaceable size 10 batteries. The size and colour codes correspond to the battery size specified for the hearing aid; they remain recognisable when you order a different pack size.

A zinc-air battery uses oxygen from the surrounding air to deliver current. The sealing tab covers the air holes during storage. Remove it when you are about to use the battery and allow a little time for the air to activate the cell. Each battery has its own tab; unused cells can remain in the pack with their tabs in place.

The division into ten blisters allows you to keep part of the stock aside and take a blister of 8 spare batteries with you. This item is the Rayovac Extra version in size 10. The total of 80 batteries does not change the characteristics of the individual cell; you are ordering the same size in a larger stock pack.
