Battery Life
How long should your batteries last? The truth is there is no one answer that will work for every person.
Essentially each person has a unique hearing loss "fingerprint". No one fingerprint will be exactly alike, therefore no one person will have the exact same battery life as another.
The best way to get a good estimate on what your battery life should be, is for you to test the battery. Write down the date you put in the battery and then write the date of when you take it out. Once you have used all of the batteries in the package. You should be able to identify an average range of how long your battery should last.
