As mentioned earlier, before you buy hearing aids, it is very important to know everything about their batteries. Batteries are very delicate objects that need proper care and maintenance. The overall performance and the sound quality delivered by a hearing aid depends entirely upon the quality and strength of its batteries. Here are some common questions asked by hearing aid users or prospective hearing aid buyers worldwide -

Ans. - If you often experience distortions in sound or you are having to frequently turn up the volume more than usual, then it is high time that you must change your hearing aid batteries. It is advisable to carry hearing aid batteries always with you whenever you go outside your home; it is because batteries often drain out all of a sudden. Some hearing aids, however, make a small beeping sound to indicate that they are weakened.
Ans. - It is always advised to remove your batteries always when you are not using your hearing aids, such as at night or while you are taking a bath. Putting them on when you are not using it will shorten their lifespan and weaken them soon.
Ans. - Your Audiologist might have advised you to store batteries in a case provided with the product, in a cool and dry place. Also, keep it safely, away from water, and away from the reach of children. Always refer to your product literature for other product-specific instructions about the storage of hearing aid batteries. If, however, you are out for a tour, and have to carry extra hearing aid batteries, then the best place to carry them is in your bag or backpack after putting them inside a tight container. However, keep in mind not to place them near coins, pins or other metal objects, to avoid discharging them.

It is because an unbroken seal might start to discharge the battery. Always go for unopened packages.
Ans. - First of all, prevent moisture from entering into the battery doors of our hearing aids. Moisture is a fatal killer of hearing aid batteries. Always keep open the battery doors of your hearing devices and keep them in dry kit box when they are not in use. This will help moisture to escape from within the device.
