For sale Ready-to-use Batteries EXTRAPOWER A312 1.45V Hearing Zinc Air Battery

► Brief Introduction

This battery is a button battery, which is specially designed for hearing aids. The battery model is A312, with a capacity of 160mAh. It can provide at least 6 days of battery life for hearing aids, and also provide a stable voltage of 1.45V for hearing aids to ensure the normal operation of hearing aids. The battery type is zinc-air battery. This battery uses the air outside the battery to generate electricity through a unique structure. It has a high energy density and can generate more energy than other battery systems. The battery size is 7.9mm*3.6mm, which is a very small battery. It can be used in many different types of hearing aids, such as in-ear, behind-the-ear, and built-in receivers. It has a wide range of applicability. Because the battery is very small and can be disassembled and used, it can be carried with you to prevent emergencies, which is very convenient.

► Product features

1. High-quality design

The battery has good anti-swelling and anti-leakage properties, which can effectively prevent damage to the hearing aid due to battery expansion or leakage, ensure the stability and reliability of the product, provide stable power support for the hearing aid, and ensure its clear sound quality and stable performance.

2. Convenient storage

The battery packaging is sealed, and the battery self-discharge rate is low. When it is not unpacked, the battery has a long shelf life. Under the condition of suitable storage environment, the shelf life can reach 4 years, which is convenient for users to store and use.

3. Long life

Zinc-air batteries have a higher energy density and can generate more energy than other battery systems, so they can be used for a longer time.

4. Convenient to use

The battery adopts a ready-to-use design. Tear off the sticker on the battery and the battery is in contact with the air to activate the battery for use. There is no need to charge it in advance, which is very convenient.

► FAQ

Q1: What is the difference between A312 and A10 batteries?

A1: The two batteries are the same size, but slightly different in thickness: A312 and A10 have the same diameter (5.8mm), but A312 is thinner (3.6mm vs A10's 3.6mm), suitable for thinner hearing aid designs.

The battery capacity is also different: A312 capacity (160mAh) is slightly higher than A10 (90-105mAh), but lower than A13 (310mAh).

Q2: Why does A312 battery consume more power in a humid environment? How to solve it? ?

A2: Zinc-air batteries rely on oxygen reaction. Humid air will accelerate the evaporation of electrolyte, resulting in increased internal resistance; it may also cause micro-short circuits and increase static power consumption. When the air humidity is greater than 70%, the battery life may be shortened by 30-50%.

Solution: Put desiccant in the container where the hearing aid is stored during daily use to avoid moisture.

In case of emergency, when the hearing aid is damp, use an anhydrous alcohol swab to clean the contacts.

Q3: How to properly dispose of discarded batteries?

A3: This battery is environmentally friendly and mercury-free, but despite this, please put it in a battery recycling bin according to local regulations to avoid environmental pollution.
