Tomtom one xl replacement battery what version?

Hi my battery I have noticed is coming to the end if it's life.
I am trying to order one and the question being asked is what version of tomtom do I have.
How can I find this out please.
Version 1 appears to be the only battery that's different.
I have had the back off but no version on battery

Cheers
