Description
These Rayovac Extra 312 (Brown) Hearing Aid Batteries are sold in packs of six, and benefit from innovative, simpler to use packaging. The packaging features colour coding and 30 percent larger tabs, for easy access to the batteries.
The batteries themselves are made from a zinc-air chemistry, and also feature the manufacturer’s ‘Air Management System’ which ensures maximum power and optimum performance at all times. The batteries access the precise amount of air needed for them to work at their very best.
An advanced sealing process also means that the batteries have a shelf-life as spares of up to four years, and retain power effectively while in use.
