Removing the rechargeable battery
This process is not reversible.
To remove the rechargeable battery, you need a
flat-head (standard) screwdriver. Observe basic
safety precautions when you follow the procedure
described below. Be sure to protect your eyes, hands,
fingers, and the surface on which you work.
1 Remove the toothbrush from the charger,
switch it on and let it operate until it stops.
Continue to switch on the Sonicare until the
battery is completely empty.
2 Insert a flathead (standard) screwdriver into
the slot located at the bottom of the handle.
Turn the screwdriver anticlockwise to release
the bottom cap.
3 Place the handle on a solid surface with the
buttons facing up and lightly tap the housing
2.5cm from the bottom edge with a hammer.
4 Hold the handle upside down and push
down on the shaft to release the internal
components of the handle.
5 Insert the screwdriver under the circuit board,
next to the battery connections, and twist to
break the connections. Remove the circuit
board and pry the battery from the plastic
carrier.
