Because hearing aid batteries can lose power quickly, it’s important to keep an extra set nearby. Keep the batteries away from metal objects such as keys or coins, which can discharge them.
Leave the protective seal on the battery until it’s ready for use – it starts losing power after the seal is removed. However, when you do remove the seal, let it sit for five minutes before installing. This allows air to activate the materials in the battery. This can increase battery life up to three days.
Keep in mind that if you stream frequently on your hearing aid, you will lose battery power more quickly.
Time to recharge
When it comes to rechargeable batteries, silver-zinc batteries typically provide you with 24 hours of power on a 4-hour charge. Silver-zinc batteries will usually last about one year before the need to be replaced by a hearing care professional, although certain brands will last up to three years. Lithium-ion (Li-ion) batteries will hold a 24-hour charge and last about three to five years before needing replacement, usually by the manufacturer.
