Hearing Aid Batteries
We keep a supply of batteries for you to purchase in our office. Stop in routinely for fresh batteries. Make sure to check the batteries in your hearing devices often and make sure there is no dirt, wax or debris interfering with the batteries performance. Batteries that are properly charged will make a noise (a squeal) when cupped in your hand or after it has been inserted in your ear, when you cup your hand over the hearing aid it will also make a noise.
Different Types of Batteries
There are four main sizes of batteries, each with a specific color-coded package: size 10 (yellow), size 13 (orange), size 312 (brown), and size 675 (blue). The battery size you need is typically based on the size and style of your hearing aid.
Standard hearing aid batteries are zinc-air, which are activated when exposed to air, so it is very important to keep them sealed in their packages prior to use. Never open packages to move batteries to a single container; keep the packages sealed until the batteries must be used in the hearing aids, or you may end up with a dead battery. Don’t buy batteries if the seal is broken.
Battery Tips
- Once the tab is removed from the battery, it takes approximately 5 minutes before the battery is activated and the battery compartment can be closed.
- Do not force the battery door shut, as it may result in damage to the hearing aid or a broken battery compartment. If the door does not close correctly, check to see if the battery is correctly inserted.
- Do not force the battery door open too far, as it may result in damage.
- Dispose of used batteries immediately in a trash receptacle. Used batteries can harm children or pets if ingested.
- Use of a hearing aid multicleaning tool with a magnetic end may be helpful in handling the batteries.
How Do I Change My Batteries?
There are a few ways to know when to change batteries. Some hearing aids will emit a small beeping sound when the battery is low, while some will speak to the user, stating that a change of batteries is needed. Hearing aids that don’t emit warnings typically worsen in sound quality, become distorted, or simply die altogether. The hearing aids may become more quiet before the batteries die — an indication that it’s time to change them.
Note: If a change of batteries does not alleviate this problem, the device may be damaged, and it should be looked at by a hearing care provider.
