Caring for and maintaining your hearing aids
Proper care and maintenance can keep your hearing aids working effectively and extend their lifespan. A few simple daily routines and periodic checks will ensure they continue to perform at their best.
Changing Batteries
Hearing aid batteries typically last 5–7 days and need to be replaced regularly.

The most common battery size is 312 (brown), but you may have a 10 (yellow), 13 (orange), or 675 (blue). All batteries work the same, so the following steps apply to any size.
- Peel the coloured sticker off the positive side of the battery.
- Wait two minutes for the battery to fully activate (these batteries are activated by air).
- Open the battery drawer and remove the old battery.
- Place the fresh battery into the battery drawer.
- Close the battery drawer and you’re ready to go!
Tip: Make sure the positive and negative sides are correctly positioned. If the battery drawer resists closing, try flipping the battery over.

Changing Wax Filters
Many hearing aids have a small white wax filter on the part that sits in the ear canal. These should be replaced periodically, anywhere from a few weeks to twice a year, depending on your ear chemistry.

- Locate your replacement wax filters (these usually come with your hearing aid accessories).
- Remove the eardome/eartip if necessary by gently squeezing the edges and pulling it off.
- Take a new wax filter stick (or turtle shell) and locate the empty end piece.
- Insert the empty end into the white wax filter on your hearing aid.
- Pull the stick out – the old filter should come with it.
- Flip the stick over and insert a new filter into the spot where the old one was.
- Dispose of the used stick and replace your eardome/eartip.
Daily Maintenance
Performing simple daily maintenance helps your hearing aids last longer and work more effectively.

- Wipe the outside of your hearing aids with a soft cloth (similar to a lens-cleaning cloth).
- Use a very soft-bristled toothbrush to clean the microphones in a downward motion.
- Open battery drawers when not in use to preserve battery life.
- Store devices in a dehumidifying container if they’ve been exposed to humidity or water.
- Keep hearing aids away from water and moisture – avoid storing them in the bathroom.
