Hearing Aid Batteries
Hadassah Kupfer, Au.D can help with buying current or past generation batteries. Finding the right batteries to power a hearing device has become much easier with modern technology. It’s a good idea to stock up on backup batteries for emergencies or long trips. Since the hearing industry uses a uniform system for battery identification, the process is already simplified.
There are four main battery types to choose from when shopping. Yellow (10), brown (312), orange (13) and blue (675) are the most common types. They each have their own power rating, and can only fit in devices they were made for. Mixing batteries is impossible, so damaging a hearing device with the wrong type is unlikely. Hearing aid batteries use zinc-air technology for the best effect. That means once the seal is broken on the package, then the batteries must be used.
Rechargeable hearing aids
Consumers that don’t want to change out batteries can always look into buying rechargeable hearing aids. With rechargeable batteries, wearers place the device on a charging station instead of fiddling with a small compartment. This is a convenient option that isn’t mandatory but can improve the overall wearer experience. A hearing aid that uses disposable batteries can’t be converted to use rechargeable batteries. Wearers should decide which battery type they prefer during the initial evaluation. Although that decision isn’t set in stone, it can prevent buyer’s remorse at a later date. Rechargeable hearing aids are considered an essential purchase for active lifestyles or wearers that suffer from arthritis.
Even when batteries are packaged, they can be damaged. Never store batteries in direct sunlight. Heat can accumulate within the package and force the batteries to activate. Storage in extreme temperatures should always be avoided, even if it is on the cold side. Humid climates make battery storage a little more complex. Keeping batteries in a glove box or garage can be hit or miss if the outside temperature isn’t cooperative. Always store them in a cool, dry place away from any outside exposure. Temperatures between 50-77 degrees Fahrenheit are the ideal environments for all zinc battery types. As an extra tip, when buying in bulk, always open the oldest package first.
