Hearing Aid Batteries

Tips to Prolong Rechargeable Battery Life

Rechargeable batteries last about 1 year and cost about $30 each.  How long a charge lasts depends on how much you stream phone calls and media and how severe your hearing loss is.

18-19.5 hours      No streaming

16-17 hours          90 minutes of streaming

15-16 hours         4 hours of TV and 1 hour of phone streaming

1. Charging

Always fully charge the batteries, until the light in the charging dock is solid

green – it takes approximately 7 hours.

2. Out of power

If the batteries are drained and the hearing aids have switched off, never try to

get more use by opening and closing the drawer. Either:

a. Place the hearing aids in the charging dock and ensure it is powered on.

b. Insert disposable batteries and keep the rechargeable batteries safe for

charging later.

3. Not in use

If you are not using your hearing aids for an extended period of time, take the

batteries out.

Note: Avoid leaving the rechargeable batteries in the hearing aids with the

battery drawers open. This will compromise battery life.

4. Handling

Don’t keep the rechargeable batteries together with metal objects such as keys

and coins.

5. Maintenance

Wipe off any moisture on the hearing aids or charging dock before charging

using a soft tissue. Do not use rubbing alcohol or other chemical substances.

Tips to Prolong Non-rechargeable (Zinc Air) Batteries

Zinc-air batteries will last from 4 days to 2 weeks, depending on the size of the battery.  Prices vary dramatically.  At the drug store, you’ll pay about a dollar per battery.  At Costco or Amazon, it’s about 25 cents.  We have batteries too.  They’re about 90 cents each because we can’t buy in bulk.  We will mail them to you though.

1. Wait 5 minutes after you take off the tab before you put the batteries in your hearing aids.

2. Open the battery doors at night.
