Unfortunately, there is no easy answer regarding the life of a battery because there are many variables which affect battery life, including:

• the age and type of hearing aid;
• how many hours per day you use your hearing aid;
• the amount and type of environmental noise;
• the program and volume settings;
• the size and brand of the battery;
• the level of humidity; and
• how you store the batteries.

If you are not using your hearing aid for a few weeks, we recommend removing the battery from your hearing aid to minimise the risk of damage from battery leaks or corrosion by old batteries.
