Hearing Aid Batteries

There are four sizes of batteries - 10, 13, 312 and 675. It is important to choose the size that is suitable for your hearing aid. The recommended battery type can be seen in the user’s instructions received with the hearing aid. These batteries are of the Zinc Air type and need air to work. It is important that air should not enter the batteries before use. Each battery is therefore provided with an adhesive label that ensures that the batteries are sealed and fresh until use. These batteries are non-rechargeable.
Battery lifetime depends on two things:

• Type of hearing aid : Very powerful hearing aids use more power than less powerful hearing aids.
• Hearing aid usage : The consumption of power - and thus the battery lifetime - depends on the settings of the hearing aid and its use. The power consumption will vary from one hearing aid to another and from one person to another.

Please Note : When you have started using a battery, it cannot be saved for later use. Once the sealing label is removed, the battery will be activated. The battery will stop working after 4-6 weeks even if the hearing aid has not been used during that period.
