Hearing Aid Batteries 312

Signia hearing aid batteries are only activated when the protective tab is removed. The protective tab should therefore only be removed around 5 minutes before inserting the battery into the hearing aid.

Store the batteries preferably at room temperature (approx. 20°C).

An empty battery should never be left in the hearing aid any longer than necessary. Please ensure environmentally friendly disposal of the batteries.

Never allow batteries to come into contact with metal objects when stored as this will cause it to discharge. 

• Voltage - 1.45v.
• Typical capacity 310 mAh.
