A Bluetooth headset is a small device that fits behind the user's ear, allowing him to have a hands-free cell phone conversation. Most Bluetooth headsets come with a small charger, but as with any battery-powered device, the battery eventually stops holding a charge. Replacing the batter on a Bluetooth is very simple.
Step 1
Consult your Bluetooth owner's manual to determine the location of the battery door on your headset.

Step 2
Pop open the battery door on your headset with your fingernail, and tip the Bluetooth headset over so the battery slides out. Note the end that came out first--the positive or negative end. Discard the old battery.
Step 3
Insert the new battery with the same end facing outward. (Some headsets have markings on the battery door that specify the direction.)
Step 4
Snap the battery door closed.
Step 5
Put the headset on the charger and leave it there until the indicator light flashes that the battery is fully charged.
