Hearing aid batteries - FAQ

Connevans offer Zinc Air hearing aid batteries from two different manufacturers. There is no 'best' battery, different people prefer different makes and different batteries suit different hearing aids.

Hearing aid batteries come in four standard sizes:

Blue 675 size, 1.4 volt

Orange 13 size, 1.4 volt

Brown 312 size, 1.4 volt

Yellow 10 size, 1.4 volt

Once used, please recycle your hearing aid batteries. Free to use battery collection facilities have been set up at retail outlets, offices, civic buildings, schools and other public amenities around the country. It’s easy to find your nearest collection point by visiting: These schemes are funded by battery makers like Rayovac. Connevans also has a BatteryBack recycling point in our reception at our Merstham factory - if you are local, please feel free to bring in your old batteries for recycling.
