Oral-B Pro Battery Toothbrush, 2 Batteries Included (packaging may vary)

Product Information

The PRO 3, on top of the Daily clean and Sensitive modes, comes with a specialized whitening clean mode. Experience Oral-B Pro 3 from the #1 brand used by dentists worldwide. The sleek handle of the Pro 3 electric toothbrush helps you brush like your dentist recommends: It helps you brush for 2 minutes with the professional timer and it notifies you every 30 seconds to change the area your are brushing. While you are just moving the brush around your mouth, Oral-B's unique round head does all the rest. Measure your battery and if it is 42mm long you might have the option of fitting a longer battery instead. Because it is physically larger, a longer battery will have a higher electrical capacity (mAh) and will run for longer between recharges. Do you notice how the metal tag on the positive terminal extends horizontally away from the battery? Take a look at the picture below to see how the positive tag extends through some empty space inside the handle. Then it’s on to the copper wire solder points for the charging coil (arrowed below, right) and the pressure warning light (arrowed below, left). Carefully desolder these and lift the wires away from the circuit board trying not to melt the plastic around them. I didn’t get a flashing red light when resoldering the battery but I assume the battery was supplied with no charge in it.

This feature protects your gums by signalling you if you're brushing too hard. The 360° pressure sensor turns red and automatically slows brush speed. To start off, remove any brush heads from the top of the handle. Stand the toothbrush tip-first in hot water (60 degrees C) for 5 minutes to soften the plastic and make the ring easier to remove. Use the screwdriver to pry off the plastic ring from around the shaft. Note that the ring is stepped so you might need to press down into the soft coloured surrounding material to lever the ring from underneath. Alternatively you can use pliers with tape inside the jaws to stop them marking the ring. The Lithium-Ion battery holds a charge that can last more than two weeks. The charging station is small enough to fit on a bathroom counter or sink. The tip above about where to press the handle to get the base off was a great one and should be in the instructions. Additional heating did not hurt and nothing broke. Unclip the carrier for the pressure warning light wires and gently remove the carrier from the top shaft (arrowed below) then put it to one side.AA BATTERIES MAY HAVE DIFFERENT VOLTAGES. DO NOT USE ANY BATTERY WITH LABELLED VOLTAGE OVER 1.5V OR DAMAGED BATTERY AS THIS MAY CAUSE DEVICE OVERHEATING. Make sure you are not charging the toothbrush on a metal surface. The metal can interfere with the charging process.

All system components (e.g., toothbrush handle, charger, power cord, SmartGuide). You do not need to include accessories like the brush heads or refill stand. Remove the handle from the charger and the base of the handle should come off. The spring might fall out so don’t lose it! Oral-B's round head surrounds each tooth for cleaner teeth and healthier gums, removing up to 100% more plaque vs. a manual toothbrushPower up to a better clean with the Oral-B Pro-Health Precision Clean battery-powered toothbrush. Your teeth and gums will feel pampered because you're removing more plaque than a regular manual toothbrush each time you brush. An excellent repair guide. I would not, however, recommend this as a first attempt at repairing anything. A very fine point soldering iron and needle nosed pliers are essential and great care must be taken. There are many very small surface mounted components and care must be taken to avoid displacement or damage of these. Similarly, the amount of solder applied should be minimal as components are closely spaced and short circuits must be avoided. Having said all this, if you have a toothbrush that doesn’t work, what have you got to lose? Just take your time and go carefully. At this point you might realise that you have fallen victim to Braun’s designed-in obsolescence and non-repairability if the plastic tab at the front of the base breaks off. This makes it more difficult for the toothbrush to be repaired (see below.) If you need to change batteries, open the lid as shown in the picture. Clean the area and the rubber ring underneath the cover. Insert two 1.5 V type AA (LR6) batteries as shown. Be sure you’re charging for the full time noted in the manual. For iO series as of 7 it takes 3 hours. For iO 6, Genius and Smart range and Pro 3 it takes 12 hours. For our Vitality toothbrushes, that’s 16 hours. For the other brushes, they should be charged for up to 24 hours.
