Hearing Aid Battery Care
We want our customers to get the most out of our batteries, as we are proud of the long lasting potential we create. We’ve put together a few tips on how to get the best performance from your Rayovac batteries.
Battery handling safety recommendations:
1. Please store all small batteries out of sight and reach of young children.
2. Ensure the battery compartment of any household product is securely closed and child-resistant and/or the product is stored out of the reach of young children.
3. Avoid storing small batteries in pillboxes or setting them out with medications since their shape and size make them easily mistaken for medication.
4. When changing a battery, never hold batteries in the mouth.
5. Seek immediate medical attention if a battery is ingested or inserted.
6. Fire – Never dispose of batteries in a fire. They may rupture, releasing internal ingredients.
7. Promptly remove dead or weak batteries from devices.
8. Never mix old and new batteries in a device. Battery leakage may occur. Replace all batteries in a device at the same time.
9. Never mix battery types in a device. Battery leakage may occur.
10. Carefully install batteries in the correct polarity direction ( + and -) per the device manufacturer’s instructions.
11. Do not leave battery powered devices switched “on” after the batteries are exhausted. Battery leakage may occur.
12. Remove batteries from any device that will be stored for long periods of time.
13. Do not allow batteries to contact metal objects or other batteries – may leak or rupture.
14. Do not recharge zinc air batteries, may leak or rupture.
15. Do not try to disassemble batteries.
16. Store batteries in a cool, dry location. Avoid temperature extremes. Keep batteries in original package until you are ready to use them.
17. Battery Safety information - To make sure our you and our customers are as safe as possible, we like to make sure you are fully informed, and how to be safe and make sure it never happens to anyone you know. Click HERE to get the information.
How Hearing Aid Batteries Work
The most common type of hearing aid batteries on the market today use zinc air technology which means air from the atmosphere is the active ingredient. Once the tab is removed, you can see the tiny holes in the battery; these holes are what allow air to enter the battery and power it up.
Air Up Time
After the tab is removed, allow the battery sit for 1 minute untabbed before inserting the battery into the device. The reason to let it sit is because the air needs time to get into the battery. Taking the tab off and immediately putting the battery in the hearing aid limits the amount of air it is exposed to. This could cause the battery to seem “dead” because the voltage could not reach the necessary level to power the device. If this happens allow air to enter the cell and increase the voltage. After 1 minute, put the battery back into the device.
Fresh is best
Like all batteries, zinc air hearing aid batteries will slowly lose charge over time (less than 10% per year with a tab). To get the most from your batteries, purchase batteries frequently. The fresher they are the better they perform.To ﬁnd out the best before date see the 4 digit date code on the reverse of the pack.
Battery voltage and lifetime
While it says 1.45 volts on the battery package, a tabbed voltage will measure 1.1 - 1.3 volts. After un-tabbing, voltage will rise enough to power a hearing aid. The cell may need several hours to rise to maximum 1.45 volts.
It is common for people to ask how long their hearing aid battery will last. In a market survey, device users were asked how long their hearing aid batteries last. The chart shows the ranges of results and that life expectancy ranges can vary greatly. The Bottom Line - There is no one answer that is going to work for all hearing aid wearers. The best way to understand the battery life is for an individual to benchmark their battery performance over time.
Factors affecting battery life
There are many factors that affect how long a hearing aid battery lasts, below are detailed some of the most common. All these factors combine to make a person’s hearing loss experience as unique as a person’s “ﬁngerprint”.
An individuals hearing loss - As severity increases, increased ampliﬁcation is required which increases the current, and therefore reduced battery life.
Sound Environment - The noise around you can affect battery life. A battery will drain less in a library versus a restaurant or rock concert. Also, if the volume is “maxed out” on your hearing aid this will prematurely drain the battery.
Personal hearing aid usage - 2 things to take into account: How many hours a day do they wear their hearing aid? How many days a week do they wear their hearing aid?
Dryness - As humidity is reduced, batteries may dry out reducing the battery life
High Humidity - As humidity increases batteries may take on moisture, interfering with the natural discharge expansion.
Altitude - As altitude increases the percentage of oxygen in the air is reduced. This can cause the battery to reach the endpoint earlier.
Temperature - As temperature is reduced, hearing aid battery voltage is lowered, which reduces battery life.
The more advanced the aid is, the more power is required. Features in today’s digital instruments like wireless streaming, bluetooth connection and noise cancellation all require high current to function. Below you can see how the current demands (mAh) on the hearing aid batteries change as the more advanced features are used:
How should I store my batteries?
Store your hearing aid batteries at room temperature.
Avoid storage in hot places as this shortens the life span.
Batteries should not be stored in the refrigerator.
Batteries should be stored in supplied dial packs and not carried loose in your pocket as metal objects can cause a battery to short out, leak or rupture.
Keep batteries out of reach of children.
How can I recycle my old batteries?
Under the European Battery Directive all batteries must be recycled, there are multiple facilities set up in your local retail outlets, ofﬁces, civic buildings, schools and other public amenitie.
How often should I change my battery?
Once you become familiar with your hearing aid and batteries, you can determine which system works best for you. Always carry spare batteries with you at all times.
