At the end of the instructions you could add info on whether it is possible to test the toothbrush without fully assembling it first. That would save a lot of aggravation because the disassembly is so iffy. You now have the option to either replace the old battery with one of the same physical dimensions or modify the plastic housing to accept a longer, higher capacity 49mm battery. Please support us with writing these repair guides by buying your replacement battery through the links to our secure online shop shown. The original-sized 42mm x 14mm batteries are 1200mAh capacity and the longer 49mm x 14mm batteries are 2200mAh, over 80% higher capacity! Higher capacity means your toothbrush will run for longer before it needs recharging. See the picture below for (left to right) replacement 42mm battery, original 42mm battery and replacement 49mm battery. The first piece to remove from the internal assembly is the power switch plate. This is clipped in on both sides at the top of the brush, see the arrows below. Carefully unclip it from one side, then the other: I found the plastic of the battery holder to be harder than I expected and, although I removed most of the webs with a scalpel, I found a Dremel was good at removing the last pieces. Compatible with Oral-B brush heads for every oral care need: CrossAction, FlossAction, Precision Clean, 3D White, Sensitive Gum Care, Deep Sweep, Dual Clean. Does not fit iO brush heads
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. Oral-B PRO 3 and brush heads are designed to work together for an optimal clean. From CrossAction to Precision Clean, to 3D White, to Floss Action, Oral-B brush heads deliver a superior clean vs. a manual toothbrush. 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! I didn’t get a flashing red light when resoldering the battery but I assume the battery was supplied with no charge in it.Time to get your soldering iron warmed up now! Starting with the negative one (nearest the coil of copper wire), use the soldering iron and desolder pump to carefully desolder the two battery terminals on the circuit board (arrowed below, positive on the left and negative on the right) and bend the metal tabs vertical and away from the board with a knife so there is no solder left joining the solder tag to the board. Desoldering braid might also be useful for this. 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.
To avoid brush head breakage which may generate a small part choking hazard or damage teeth: Prior to each use, ensure the brush head fits well. Discontinue use of the toothbrush if brush head no longer fits properly. Never use without a brush head. If the product is dropped, the brush head should be replaced before the next use even if no damage is visible. Oral-B toothbrushes are designed with dentists and are the number one toothbrush brand most used by dentists worldwide. The Oral-B Pro 1000 rechargeable toothbrush provides a clinically proven superior clean vs. a regular manual toothbrush. The professionally inspired design of the CrossAction brush head surrounds each tooth with bristles angled at 16 degrees, and 3D cleaning action oscillates, rotates, and pulsates to break up and remove up to 300% more plaque along the gumline than a regular manual toothbrush. The pressure sensor stops pulsations if you brush too hard to prevent harmful over-brushing and there are 3 modes, plus an in-handle timer to help you brush for a dentist-recommended 2 minutes.
How-To
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. 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. 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. 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. If fitted, locate the solder point for the pressure warning switch (arrowed below) and desolder it. Then unclip the switch and put it to one side.
minute coaching timer. ProCore constant power delivers optimal performance every time. 2 AA batteries included. It removes up to 100% more plaque than a standard manual toothbrush for healthier gums and it starts making your smile whiter as of the first day of brushing by removing surface stains. Not only this, but the toothbrush helps you protect your delicate gums with the 360 ̊gum pressure control technology that reduces brushing speed and alerts you to be gentler if you brush too hard. 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. If it hasn’t already fallen out remove the spring from inside the coil in base of the handle and put it somewhere safe.

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. 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.)
Depending on which model you have, it should take between 3 and 22 hours to fully charge the brush. If this hasn’t been your experience, there are a few things you can try.
Will you be claiming the VAT back?
