What do you do if the screws strip? they are really cheap
Where does one get the actual battery replacement from?
You must use a very small blade Phillips screwdriver. A #0 will be too big. Significant downward pressure is also needed to break the screw loose and prevent stripping the screw. It feels like they are glued in. The battery is available in many places and is a 14500 type rated at 750mAh with a 4mm tab on the positive side and a 2.5mm tab on the negative side.

If you happen to lose the two springs, you can cut off 2x10mm of a spring from a pen :P
Merry trimming and a happy new beard !
I bought a set of Draper screwdrivers specifically for this. Can’t shift any of the screws. Ideas?
The screws holding the body together seem to be of poor quality and possible glued in place, I only managed to remove one with quite a high quality screwdriver and had to drill out the others. Taking this apart takes longer than 15 mins on it’s own leave alone doing repairs.
On a MB4045 model, I can confirm that the screws are glued into the plastic and cannot be unscrewed. I had to Dremel out the heads and dremeled a fair bit of plastic in the process. These trimmer model are designed for planned obsolescence. Shameful. The whole disassembly took me 1hr +

In diesem Schritt verwendetes Werkzeug:Spudger$3.99
-
Entferne den Thermoschalter vom Akku, indem du einen Spudger benutzt, um ihn vom Klebstoff zu hebeln.
-
Entferne den Akku, indem du ihn vom Motherboard entlötest.
Thx! But how do you get the thermal switch back again? It seems I can’t just put it back by itself. Can you glue it back or something?
Ideally you should use a “thermal conductive glue”. You can search online for it. For me this was a non-critical fix so I just used a small amount of fabric glue which will stay flexible so I can take it off again next time, if there is a next time.

Great work - but help on where to source the battery would be good too :)
It's available as a generic - it's a '14500' Li-Ion battery, 3.7V - typically 750-800mAh. Dimensions: 50mm x 14mm (diameter).
I have seen two types of these batteries: protected and unprotected. Which type do we need?

You did everyrhing except the most important part to me
How did you unsolder the battery, and solder the new battery?
I was going to buy the tools from the local store but realized i don't know how to appropriately unsolder/solder battery tabs.
Non the less you are the only one who made such explanation, thank you.
If you happen to lose the two springs, you can cut off 2 pieces from the spring of a pen :P
Merry Trimming & A Happy New Beard !
The connectors to the battery were in my case spot welded not soldered which created some problems. Soldered both connectors from the circuit board together with the battery. Successfully drilled away the welding points, and then used the now rather demolished connectors again. Soldered the new battery. Not beautiful but it works.
Use 3 times only,but not charged
Didn’t have a soldering iron. I pried the battery tabs off the battery and used conductive tape to secure them as a workaround. Not ideal but seems to be holding so far
Thanks! The guide worked a treat on my MB4045. Having a second person hold the board and battery during the soldering helped immensely. For my MB4045 I used the A14500HD10FT (version A) battery from ecoluxshopdirect.co.uk. Lets hope this lasts for another 5+ years. Thanks again to all who contributed to this guide!
Agreed, guide worked well for 4045. Had to adjust width of tab to fit into the negative hole on the board. I ended up folding it and that worked. The positive tab on the stock battery required some wiggling as it was like it had been folded down onto the PCB
