  • Remove the seat by unscrewing the single screw located just by the backrest

  • Unscrew the battery restraint

Step 2

              Disconnect the existing battery
  • If you are replacing with an official replacement then it’s a simple case of unclipping the old battery.
  • Alternative battery
  • If however you are swapping in an alternatively sourced battery you will need to cut off that clip.

              When to replace the battery?
  • The condition of the battery can most easily be told by charging it and seeing how much use you get out of it before it needs recharging again.
  • However if you have a multimeter then you can also look at the voltage of the battery.

Step 4

              Replacing the new battery
  • If you are using a official replacement battery this again should be a simple case of clipping the new one in place.
  • Finish up by replacing the restraining clip making sure to avoid trapping any wires. Replace the seat up by sliding it firmly forwards then screwing down
  • Alternative battery
  • Crimp or solder on suitable connectors for the new battery ensuring that the red and black wires are connected to the same connectors on the battery.
  • It is a good idea to ensure that the battery can disconnected for future diagnosis, external charging or replacement

Can I use 2 6v battery’s to make this train go faster??

If you use a 12v or two 6v attached in series it could damage the sound board.

Two 6v in parallel would give you a longer run the between charges.

The official battery is 6v 4Ah, check the dimensions against the battery compartment or old battery
