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 phone calls, TV, or music can cut runtime by 30 to 50 percent. After peeling the tab, wait 60 seconds before inserting the battery — that lets the zinc fully activate and squeezes out the longest possible life. If your batteries are dying noticeably faster than expected, give us a call so we can check for a hardware issue.

For many Sarasota patients, the answer is yes — especially if you struggle with dexterity, dislike fiddling with tiny tabs, or travel often. Rechargeable hearing aids deliver a full day of use from an overnight charge and eliminate the recurring cost (and landfill load) of disposable batteries.

That said, disposables still have advantages: instant swap-out in the field, no charger to pack, and no degraded battery capacity to worry about three years in. Most modern RIC and BTE models from Signia, Widex, Starkey, Phonak, Oticon, and ReSound are available in both versions, so the choice is more about your routine than your hearing loss. We'll walk through it together at your next appointment.

Yes. Seasonal residents and anyone with a second address can have batteries — and any other supplies — shipped directly to their out-of-state address. Just tell us how many packs you go through in a typical month and we'll set up a standing order or send a one-time refill whenever you call in.

Tip for travelers: zinc-air batteries lose capacity once the tab is peeled, but a sealed pack stays fresh for up to three years in a cool, dry place. Store extras at room temperature — not in the refrigerator. Call (941) 342-9494 to set up shipping or to request a refill on the way out of town.
