Hearing Aid Battery Ratings

Hearing aid battery ratings and questions are just some of the customer’s main concerns, as when you purchase hearing aid batteries this can sometimes be quite confusing! With the following hearing aid battery ratings and questions answered – we hope you have no more uncertainties.

Generally, a standard hearing aid battery will last between 5-14 days. This will depend on the hearing aid and battery type and how long the hearing aid is used daily. When you notice that the sound from the hearing aid is quieter than normal and/or distorted, it generally means that you need to change the battery. Some have a faint beeping sound when the battery tires. As this can happen all of a sudden, it is best to always carry a spare battery with you.

Hearing aid zinc batteries are powered by air. If there is not enough air travelling through the air vent holes, it may not work properly. Hence, when you remove the tab from the battery, it is advised that you wait for a minute to let the air get into the battery.

Some people who have hearing aids in both ears think that you need to change the battery in both ears when only one of them stops working because they want the voltage to be the same. You do not need to do this as the zinc battery is different to the alkaline battery. When the zinc battery goes bad, it will just stop as it has a flat discharge curve. The alkaline battery has a sloping discharge curve and goes bad slowly. The performance of the zinc battery should be similar regardless of where they are in the discharge cycle.

Some leave the battery door open when the hearing aid is off, as they think that it will improve the battery life. There is only slight improvement, meaning only minutes! So it is not vital!

To prolong your hearing aid and battery, it is generally recommended that you use a dry aid kit. This will help remove excess moisture. But results differ and it depends on a case by case basis. The dry aid for hearing aids and batteries are only beneficial if you are in a high humidity climate. If you live in a place where the summer is dry, for example, Arizona, the kit may shorten the life of the battery. Remember to wash your hands when you change your battery as grease and dirt can cause damage.

Hearing aid battery ratings are difficult, as battery life will depend upon how much energy is needed to run the hearing aid, how many hours of the day the hearing aid is used. Generally, the smaller the battery, the shorter its life – once it is installed in the hearing aid. Bigger batteries are usually used in hearing aids that require more power to operate. Also, the person’s lifestyle, who uses the hearing aid, may contribute to the battery life. If they are often in quiet surroundings, the battery life may be longer compared to a person who is often in a noisy environment. So you can not determine the best hearing aid batteries!
