We’ve been asked a few times for advice on opening up Braun Oral-B’s later v2 Triumph models which have no built-in LCD screen. These Triumph models have Type number 3761, 3762 or 3764 marked on the handle and open up slightly differently to the older v1 Triumph models which have a built-in screen.
Update
We have now published a full guide to opening and repairing the v2 Triumph toothbrushes by replacing the battery. Check it out!

Before starting it is a good idea to stand the toothbrush handle in hot tap water for 5 minutes (about 60 degrees C) to soften the plastic.
The first step is to put the brush on its charger and twist the toothbrush, using the charger to release the locking plug in the base of the handle.
Now you can pry the base off using a large blunt screwdriver or similar between the base and the handle body (arrowed below.)
Stand the handle upside-down in the hot water again to soften up the plastic ring around the top shaft. This can then be pried off and the internals of the handle slid out of the bottom after releasing the catches at the sides by the charging coil.
Hey guys,
Great videos and guides!
A question, when i turn the plug, is it to the left or right and how much am i to turn it?
Thanks again.
Hi, glad you like the guides! The plug in the base of the handle is turned anti-clockwise by about a quarter of a turn to release it.
I really like your easy to read guide. But I am having a terrible problem after unlocking the base getting it separated from the handle. I did soak it for five minutes and the unlocking was easy. Any further tips? Thanks!
If you remove the round unlocking plug from the base cap you can sometimes get the tip of a screwdriver under the circular lip of the cap and lever it out.
