How long do rechargeable hearing aid batteries last?
Rechargeable hearing aid batteries usually take about 3–4 hours to fully recharge and will keep your hearing aids going for around 24 hours. The battery itself should last as long as the hearing aid, which will be roughly about 4–5 years. Once you've had hearing aids for this amount of time, you should consider upgrading. But if you just need a battery replacing, bring them to us and we can help you.
Some rechargeable hearing aids are fitted with silver-zinc batteries. These batteries are removable and can be replaced easily by a hearing care expert. You can expect these batteries to last about one year.
