Most wireless headsets require a battery change in 1 to 2 years. If your battery hasn't been changed out during this time and isn't lasting as long during the day as it once did, it's likely time for a change. The 1643N battery is the direct replacement for the one that originally came with the Discover D904. It changes out super easy, allows you to talk all day long and if a recharge is needed, you can have a full charge in less than an hour.
