Several Points for Attention of Rechargeable Hearing Aid Amplifier Battery

Safety differences

Silver-zinc batteries work at a low voltage (1.6-1.7V), which is non-toxic and non-flammable, which means that they can be safely operated and have a lower risk of being swallowed by mistake. On the other hand, lithium-ion batteries operate at higher voltages (3.6-3.7V), and there are considerable risks associated with flammability and toxicity. Because of these risks, lithium-ion batteries are sealed into the original hearing aid.
Disposable batteries as standby batteries

Disposable batteries as standby batteries

Because of the safety of Ag-Zn technology, Ag-Zn rechargeable hearing aid amplifier batteries can usually be removed from the hearing aid housing and exchanged with disposable zinc air batteries. This gives hearing aid users the flexibility to "leave the rechargeable power supply (power failure)" and use disposable batteries for a period of time.

How long can a rechargeable hearing aid amplifier last after a charge?

ZPower recently completed performance tests on four popular rechargeable hearing aid amplifier models to determine the service life of Ag-Zn rechargeable hearing aid amplifier batteries after one charge. According to the type of hearing aids and the number of hours of wireless transmission, rechargeable batteries provide the use time from 7.7 (full-time wireless) to 24.7 (non-wireless) hours.

Differences between Hearing Aid Types

Tests on the machine show that there is a significant difference in the usage time from one type of rechargeable hearing aid amplifier to another type of rechargeable hearing aid amplifier. Products that use new low-power Bluetooth circuits have a longer life than their regular batteries, regardless of how much time they spend on wireless transmission.
