    • However if you have a multimeter then you can also look at the voltage of the battery.

I need a new battery 6v for Thomas ride on train.

Can you pls recommend a brand? Or can I use 12v instead ? Thanks - Contestar

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

Reggie - Contestar

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

When replacing battery on the train the negative wire came off a little silver rectangular piece hooked to it what is this part and do I need it or can I bypass it

Hey Leonard, are you talking about “spade connectors" ? It's a good idea to have the battery so that it can be quickly disconnected, soldering the wires to the battery would be a bad idea
