Best Hearing Aid Batteries

The Best Hearing Aid Batteries cost around $1.25 each, or as little as 55 cents when you pay $26.90 for 48 on Amazon.

The type of hearing aid batteries you choose will, of course, depend on the hearing aid you chose. Therefore, the ease of changing the battery should be considered when selecting the hearing aid. Batteries, like hearing aids, come in several sizes and if your manual dexterity is limited, you may prefer a hearing aid that uses a larger battery that is easier to handle and replace. In-the-canal (ITC) and completely-in-the-canal (CIC) hearing aids are the smallest hearing aids and will usually have the smallest batteries.

Leave the tabs on the batteries undisturbed until you need the batteries. Most hearing aid batteries are of the type called “zinc air.” The power is generated by mixing zinc metal with the oxygen of the surrounding air. This mixing begins as soon as the tab is taken off a new battery, and replacing the tab does not stop the process.

Know your battery’s size and color code to make replacement purchases easier. The most commonly used batteries have blue tabs and are size 675. Yellow tabs are found on size 10 batteries. Brown tabs indicate size 312, and orange tabs denote size 13. The smallest batteries are size 5 and are red.

Note: Service plans like the Sonus Solutions package, include up to three years worth of batteries.

The service life of the best hearing aid batteries should be 6-7 days when used full-time. If batteries consistently last less than 6 days, have your hearing aid examined by a professional; it may need repair. The shelf life of new batteries is three years if the tab remains intact and they are kept at moderate temperatures. An increasingly noticeable loss of strength occurs after that time.

Batteries should also be kept from hot temperatures because the tabs are attached with glue. The glue may get soft in hot environments and admit air into the battery just as if you had removed the tab. This begins the power generation process and ultimately the degradation of the battery as if it were in use, even if the tabs reseal in the correct place when the temperature drops. This means you should keep your batteries out of hot cars in the summer, out of cabinets that are just above an oven, a toaster, or any other source of heat.

Keep fresh batteries separate from used batteries simply to avoid confusion about the size of your supply. (You may be saving used batteries for recycling.)
