Hearing Aid Batteries

Battery life depends on size, how much streaming you do, and how loud your typical environments are. As a rough guide: size 10 batteries last 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 calls, TV, or music can cut those numbers by a third to a half. One habit worth adopting: after you peel the tab, wait a full minute before closing the battery door. That lets air activate the zinc and buys you meaningfully longer life. If your batteries start dying faster than they used to, call us, because that is often the first sign of a hardware problem rather than a bad pack.

For a lot of patients, yes. If arthritis has made the battery door a daily annoyance, or you have simply had enough of losing tiny cells on the carpet, rechargeable hearing aids solve it. An overnight charge covers a full day of wear, and the recurring battery expense disappears.

Disposables still have their arguments: a fresh cell in seconds when you are away from home, no charger to remember on a trip, and no capacity fade after a few years of charge cycles. Most RIC and BTE models come both ways, so this is a question about your routine rather than your hearing. Bring it up at your next visit and we will work it out.

Zinc-air cells begin draining the moment air reaches them, which is why the tab matters. A sealed pack keeps for about three years if you store it sensibly: room temperature, dry, in a drawer or cabinet away from the stove and the window.

Three things to avoid. Skip the refrigerator, because condensation does more harm than the cold does good. Do not carry loose batteries in a pocket with keys or coins, since metal across both contacts will short them. And leave the tab on until you are ready to use the cell. A parked car in a Chautauqua County July gets hot enough to ruin a pack, so keep them inside. Call (716) 708-4343 to stock up.
