-
Before handling the batteries, wash and dry your hands to keep the batteries clean and maximize battery life

Gently pull the tab on the bottom of the hearing aid until the battery door fully opens

Push the battery out through the back of the battery door
Tip: You can use the magnetic end of the cleaning brush to easily remove the battery -
Insert the new battery with the sticker side (the smooth side with a + marking) facing up
