I worked on this stairlift today and fitted a proper 20 cell 3 stage NiCad charger. ( cooking the batteries will not happen.)
The beeper wouldnt shut up of course but was easy to remove.
Setting the datum is the biggest problem as I had to temporarily refit a 33v power supply to the charge point, remove the wires to the battery and reconnect the charge pick up plug on the board. Not ideal!
I imagine the stairlift will still give the b battery error code as it must be a function of battery voltage and independent from the charge circuit.
So it works but I wouldn’t recommend it unless you have no other option.
All advice appreciated – I will let you know how it pans out long term.
