Bob’s battery is located on his underside, just above his main brush. Use a Phillips head screwdriver to uninstall the two screws securing the battery cover.
Remove the battery cover and lift the old battery out of its compartment.
To disconnect Bob’s battery, pinch and pull at the circuit junction.
Once the old battery has been removed, you may connect your new battery.
Tuck the wire into the side of Bob’s battery compartment and slide the new battery in.
When done, replace Bob’s battery cover so that it lays flat and reinstall the 2 screws.
