Cellion primax is the world’s first hearing aid with lithium-ion inductive charging. Ideal for customers who don’t want the fuss of changing batteries, Cellion primax starts charging automatically as soon as it is placed in the charger. And, with its smart electronics, it turns on automatically when it’s taken out again. Its rechargeable lithium-ion power cell lasts 24 hours straight without charging and – with no contacts or battery door – its unique OneShell design makes it superbly easy to use.
