Battery Terminal Posts On T120

Good morning @learningtofly, gosh you get going early!

Triumph fit the same battery to pretty much all the "Modern Classics": I've checked the handbooks and yours will be the same as mine.

So I popped out to the garage and measured mine. If by "the battery posts" you mean the hex bolts (with a Cross head driver slot in the top) that clamp the cables to battery itself, they are M6.

Which is what I expected; an M8 bolt would be a big terminal, probably moving into small car territory.

Hope that helps.
