Hearing aid batteries last anywhere between five and 14 days depending on the above factors. You will know it's time to replace your hearing aid batteries when the aids start beeping. One solution to save money and make batteries last longer is to purchase rechargeable batteries.
This means that from the time they are produced, they can sit in the box dormant (non-functioning) without losing any strength. So, when you purchase your hearing aid batteries, look for a box with a date the furthest out: a February 2014 date is better than a September 2013 date, for example. The life expectancy of your hearing aid battery really depends on the type of hearing aid you have and how long you wear them each day.
