Zinc Air Battery Description

New Arrivel 1.45v 1.4v Size A10 A13 A312 A675 zinc air button cell hearing aid battery

If you use hearing aids, you might know the zinc air battery. It's a special kind of battery that requires special care. 
The way the zinc air battery works is very different from other standard batteries. The zinc air battery is completely filled with zinc, which reacts with oxygen from the air when the seal is removed (see below). Even as a small battery, it has a lot of energy stored. Moreover, it holds its voltage for a long time. With these two properties, this battery proves itself to be a very good battery. 
One of the main benefits of zinc-air batteries is its longevity while sealed. A zinc-air battery with a pull-tab can sit for upwards of three years and still retain nearly 100% of its overall capacity. Larger models with more effective seals may last indefinitely. After they are first exposed to oxygen, zinc-air batteries discharge relatively quickly and should be used immediately.

FAQ about Zinc Air Battery

What you should know about the Zinc Air Battery

1. Remove the tab

Most importantly: do not forget to remove the tab before inserting the battery in your hearing aid. This tab is on the backside of the battery and closes off 4 little holes. Without removing the seal, the battery already has a voltage of 1,1 V to 1,3 V, but removing the seal will cause oxygen to flow into the battery, which will increase the voltage to 1,45. When you do not remove the seal, the hearing aid will work, but only for 1 to 2 days. Be sure to remove the seal to guarantee a long lifespan and optimal functioning.

2. Wash your hands

When dirt or grease touches the battery, this could cause faster discharge, or – worst case scenario – short-circuit, which can be harmful. Both kinds of problems can be prevented by washing your hands before touching the battery when you want to replace the batteries.

3. Let the battery breathe

When you have removed the tab from the battery, you should always let it 'breathe'. What does that mean? It's simple: without air, the battery won't work optimally. After removing the tab, let it breathe for at least 1 minute or, for the best results, 5 minutes. Then, put it in the battery holder of your hearing aid. By respecting this 'breathing time', you will extend the lifetime of your zinc air battery up to between 30 and 80%. If you remove the tab and immediately put the battery in your hearing aid, this will have a negative effect on the lifespan of your battery.

4 tips to take the best care of your zinc air batteries

Now you know that zinc air batteries are special batteries that need special care. Washing your hands, removing the tab and letting it breathe are the most important usage tips, but here are four more tips. If you take these into account, you will be able to prolong the shelf life of your zinc air batteries.
