Description
Colour coded and specially designed packaging makes Rayovac Extra 675 (Blue) Hearing Aid Batteries (6 Pack) a straightforward battery to use, with each battery sliding simply out of the colour coded packaging, thanks to the front facing tabs. Their four-year freshness date code also means that they can last for years as spares, if stored according to manufactur’s instructions.
Rayovac’s ‘Air Management System’ also means that these batteries can maximise their power without diminishing performance. These Zinc-air batteries offer consistent quality, due to the advanced sealing methods used by the manufacturer. The design means that they access the precise amount of air needed, maximising performance and minimising power drain.
