How often will I need to change the batteries of the CRE-C10 OTC hearing aid?
The battery life on the CRE-C10 is 70* hours or about 5-7 days of normal usage. When you’re not wearing your OTC hearing aids, we recommend leaving the battery door open to conserve battery life. You may want to keep a few spare batteries handy just in case you have to change them on the go.
*Actual performance varies based on settings, environmental conditions, and usage.
