Removing the rechargeable battery
Warning: Only remove the rechargeable battery when you discard
the appliance. Make sure the battery is completely empty when you
remove it.
To remove the rechargeable battery, you need a towel or cloth, a
hammer and a flat-head (standard) screwdriver. Observe basic safety
precautions when you follow the procedure outlined below. Be sure
to protect your eyes, hands, fingers, and the surface on which you
work.
1 To deplete the rechargeable battery of any charge, remove the
handle from the charger, turn on the Philips Sonicare and let it run
until it stops. Repeat this step until you can no longer turn on the
Philips Sonicare.
2 Remove and discard the brush head. Cover the entire handle with
a towel or cloth (Fig. 19).
3 Hold the top of the handle with one hand and strike the handle
housing 0.5 inch above the bottom end. Strike firmly with a
hammer on all 4 sides to eject the end cap (Fig. 20).
Note: You may have to hit on the end several times to break the
internal snap connections.
4 Remove the end cap from the toothbrush handle. If the end cap
does not release easily from the housing, repeat step 3 until the
end cap is released (Fig. 21).
5 Holding the handle upside down, press the shaft down on a hard
surface. If the internal components do not easily release from the
housing, repeat step 3 until the internal components are released
(Fig. 22).
6 Remove the rubber battery cover (Fig. 23).
7 Wedge the screwdriver between the battery and the black frame at
the bottom of the internal components. Then pry the screwdriver
away from the battery to break the bottom of the black frame
(Fig. 24).
