STEP 2 Activate The Battery Allow the battery 1 Minute to rest after removing the tab. STEP 3 Place The Battery In The Device Insert battery in your hearing aid with the air holes facing up. STEP 4 Enjoy Every Moment Close your hearing aid and enjoy every moment of your Rayovac hearing aid battery. Activate 1 Minute To activate the battery, remove battery tab and let the battery sit un-tabbed for one minute before placing it into your hearing aid. Why? 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. How to store the batteries Hearing aid batteries should be stored at room temperature in supplied dial packs and not carried loose to avoid short circuit. Important: Keep discarded batteries away from infants or children. Factors affecting battery life How long your hearing aid batteries last depends on various factors: The degree of your hearing loss, personal hearing aid usage, differences in devices as well as several environmental factors, such as low temperature, high humidity, dryness, high altitude or a noisy environment. How long do the batteries last How long your hearing aid batteries last depends on various factors, so there is no general answer that is going to work for all hearing aid wearers. The best way to understand the battery life of your hearing aid battery is to benchmark the battery performance over time. Once you become familiar with your hearing aid and batteries, you can estimate when the life of your battery will end. Therefore it is always important to carry spare batteries with you at all times.
