This collection covers the essentials for hearing aid care, including batteries in common sizes and practical accessories for cleaning, moisture control, and wax protection. If your hearing aid feels weaker, cuts out, or sounds inconsistent, the right battery size and a simple care routine with drying and cleaning tools can help keep everything running smoothly.

How to choose

• Battery size: Match your device to the correct size (10, 13, 312, 675, or 675P). If you are unsure, check your current pack or your hearing aid manual.
• Pack size and value: Choose a single card for convenience or larger multi-card options if you use the same size regularly.
• Moisture control: If you live in humid conditions or exercise often, consider a drying option like drying capsules or a drying kit to help reduce moisture-related issues.
• Wax and debris care: If wax buildup is a recurring problem, add a wax guard option and a maintenance tool set to keep ports and openings clear.
• Quick checks: A battery tester helps confirm whether a battery is truly flat before you discard it.

FAQs

How long do hearing aid batteries last?

Most hearing aid batteries last days to a couple of weeks depending on size, usage time, and your hearing aid settings. Streaming and higher amplification can reduce battery life, while consistent daily use makes it easier to predict replacement timing.

What battery does a hearing aid use?

Most hearing aids use zinc air batteries in sizes 10, 13, 312, or 675. Check the size printed on your current battery pack or compare the number on the battery itself to select the correct replacement.

What is the 5-minute rule for hearing aid batteries?

The 5-minute rule is to remove the tab and wait about five minutes before inserting the battery. This can help the battery reach full output more reliably, which may reduce early dropouts or weak performance right after a change.

What is the life expectancy of a 312 hearing aid battery?

A size 312 battery commonly lasts several days for many users, but results vary by device and daily wear time. If you notice shorter life than usual, check for moisture, wax buildup, or a poor fit in the battery door.

How do I know I am buying the right battery size?

The safest method is to match the number on your existing pack: 10, 13, 312, 675, or 675P. If you are switching brands, the size number stays the same, so you can keep the same size and simply choose your preferred option.

Can moisture affect hearing aid performance?

Yes, moisture is a common cause of intermittent sound and performance issues. Using drying capsules or a drying kit as part of your nightly routine can help reduce moisture buildup and support more consistent operation.

What is a battery tester used for?

A battery tester helps you confirm whether a battery still has usable power. It is handy when a hearing aid sounds weak, so you can quickly check the battery before replacing it.

How do I clean earmoulds safely at home?

Use an earmould cleaning routine that focuses on cleaning accessories rather than soaking the hearing instrument itself. Options like earmould cleaning tablets and a cleaning beaker with basket can support a simple, repeatable process.

What are wax guards and when should I replace them?

Wax guards help slow wax intrusion into the hearing aid and can reduce blocked sound outlets. Replace them when sound becomes muffled, wax buildup is visible, or your usual cleaning no longer restores clarity.
