Hearing Aid Batteries

Runtime tracks with battery size, how much you stream, and how loud your usual surroundings are. As a rough guide: size 10 lasts 3 to 7 days, size 312 lasts 5 to 10 days, size 13 lasts 9 to 14 days, and size 675 lasts 14 to 21 days.

Heavy Bluetooth streaming for phone calls, TV, or music can cut those numbers by a third to a half. One habit worth adopting: after peeling the tab, wait 60 seconds before inserting the battery, which lets the zinc fully activate and buys you the longest life the cell can give. Batteries dying much faster than the ranges above usually point to a hardware problem, so call the office and we'll take a look.

For a lot of patients, yes, particularly if dexterity is getting harder, if tiny tabs frustrate you, or if you travel often. Rechargeable hearing aids give you a full day from an overnight charge and end the recurring cost and waste of disposable cells.

Disposables keep some real advantages though: an instant swap when you're out for the day, no charger to pack, and no gradual loss of capacity a few years in. Most current RIC and BTE models are built in both versions, so this comes down to your routine rather than your hearing loss. We'll sort it out together at your next visit in Zionsville.

Zinc-air cells begin losing capacity the moment the tab comes off and air reaches them, but a sealed pack stays good for up to three years when it's stored sensibly. Room temperature in a cool, dry spot is all it takes, so a drawer or cabinet is fine.

A few things to avoid: the refrigerator, where condensation does real damage; carrying loose batteries alongside coins or keys, which can short them out; and peeling the tab before you actually need the cell. A parked car in an Indiana July gets hot enough to hurt them too, so keep spares indoors. Call (317) 973-8098 if you'd like to stock up.
