The performance of a hearing aid primarily depends on the type of hearing aid battery used. Just like any other electronic device, hearing aids require high quality batteries that drive them correctly.
More importantly, a hearing aid requires a fresh battery. You are always getting a fresh supply of batteries from our office as our supply is always replenished within 60 days.
How does one determine the quality of a battery?
Zinc air cells are most commonly used to operate hearing aids. It is recommended that multiple hole rather than a single hole battery be used with any hearing instrument.
To find the air inlets, look at the top side of the battery. A single hole battery will only have one air inlet. A multiple hole battery will have anywhere from 2 to 6.
The problem with single hole batteries is that the battery contacts within the hearing aid may occlude the air entry. This prevents the battery from receiving sufficient air exchange to operate. Without sufficient air through the battery, the hearing instrument will malfunction.
When removing the battery tab of the air cell battery, always wipe the battery with a dry cloth or tissue. This will remove any sticky residue that may be left on the battery after removing the tab. This sticky residue may also affect the air exchange should it occlude any of the air inlets.
Union Hearing aid Centre carries Rayovac Proline premium zinc air batteries in all sizes. If you cannot remember the size of your battery, try to remember the colour of the battery tab. The colour of the tab corresponds to the size of your battery.
Batteries will be shipped free of charge if within Canada. Orders over $40.00 will be shipped via Xpresspost.
