Always store and discard batteries out of reach of children and animals.
Hearing aid and cochlear implant batteries should be stored in a dry place at room temperature.
Batteries (of any type) should not be stored in the refrigerator or freezer. The combination of high moisture, condensation and extreme temperatures will shorten the life of the batteries. In the case of zinc-air batteries, water particles can form under the peel-off tab - if the oxygen in the water vapour comes into contact with the zinc, the battery will activate and could be totally discharged by the time you remove the peel-off tab.
Batteries (of any type) should also not be stored in hot places or in direct sunlight, as excessive heat will shorten the life of the batteries.
If a battery gets wet it will corrode rapidly and possibly leak. Wet batteries should be removed from your hearing aid or implant processor and discarded to prevent any damage to your hearing aid or implant processor. Gently remove any excess moisture from the hearing aid or implant processor before inserting a new dry battery.
Always leave the peel-off tab on your zinc-air batteries until you are ready to use them in your hearing aid or cochlear implant. If you use a key-ring battery holder, keep the peel-off tab on the zinc-air batteries.
Do not connect the positive and negative terminals of batteries with wire. This can cause the battery to short circuit, or over-heat and it may leak or explode. For this reason, coin-type batteries taken out of their protective packaging should not be carried in your pocket or purse since metal objects such as coins, keys or jewellery can short-circuit the battery. Batteries should always be kept in their protective packaging until you are ready to use them.
When your hearing aid is not in use, keep the battery door open. This simple step will help reduce corrosion. If you use a Global or Zephyr drying kit, it is not necessary to remove the battery from the hearing aid or cochlear implant processer before putting it in the drying kit.
Batteries have a shelf life of two to three years, however it is unwise to maintain supplies to cover this length of time. To avoid deterioration of your batteries and obtain maximum use from them we recommend using older batteries first and order no more than 6 to 9 months supply of batteries.
