my oral-b has a little problem...............................

direct after a charge , when i want to use it , the brush indicates the need
for a charge !!!

sounds to me that the battery is going .

does anyone have a service manual or experience in replacing the battery.

Braun only offers a replacement hand-piece........................

some of my brief may be of use

Braun Oral B electric toothbrush , 336 base marking
Sluggish motor
Looks 1.2V , ps 2.4V and motor runs far too fast. looks as though it was a
switch problem. Running 2 to 3 amps and start 3 to 5 amps. Switch is paired
up , to take current, pair of 1mm wide prism point contacts, one being
dirty. For same reason that powering the motor from 1.2V via a pair of
croc-ended leads drops far too much power.
It is surprisingly easy to remove the base "plug" 1/8 turn
with a steel rule on edge, then dart tip to get inside
these, and no wires to break, so worth a bit of time to repair.
Make an index mark to realign on assembly, 1/8 turn back to start.
Interesting , for those with mechanical bents, double crank and rubber
mechanism creates
the motion.
Initially checking charger, with DVM Fluke 77 and 1mH small choke
measured 0.45V ac, 9 turns of wire around the location
spigot gave 0.1V ac, 0.6V when inside and the coil disconnected
and laid over the spigot,
no account made for HF not 50Hz.
Monitoring 1.2V nicad 1.24V drops to 1.16V in use.
-ve terminal to charger coil end. Coil 7.5R.
coil, thin O ring, paxolin ring then conical spring.
One motor terminal just for mounting purposes.
Good wodge of silicone grease on the active end before
fitting back in the casing.

Not sure if this applies to your unit but some units when disassembled are
designed to break the internal wiring. So pull slowly and watch out for any
tension from wires that might break easily.

Good luck.

Thanks for the additional info ,

I have repaired several old-style oral-b's , they have 2 little wires which
go from the charging adapter to the electronics,
if you don't pull them , they will survive .

BUT you have to take the internals apart in order to remove the defective
battery , which in that case is a 2,4 volt unit made of 2 x 1,2 nicd cells.

Those are diameter 17mm and length 58mm , made of 2 SANYO CADNICA N-500
( 500 mah ) cells

Mind, those are soldered to the main pcb ........................


But i have never tried the thriumph , so would like to have as much info as
possible ( triumph is a bit more expensive as a standard oral-b )
