Exide AGM EX20CH-BS dimensions

I have an exide AGM EX20CH-BS in my commando fitted with an Alton starter.
The battery has died and I need to get a replacement.
Is there somebody who can give me the exact dimensions.
Battery in France, I’m in the U.K.!
The way I’ve fitted breather and solenoid for starter means it’s a very tight fit.
Can find nothing on the internet as it seems it’s discontinued.

Specifications Exide YTX20CH-BS, ETX20CH-BS

Thanks the problem is I measured the width at 80mm before I left. Granted it was a hasty measure but I have no space for anything wider!

Probably no use to you but I have an odyssey pc 680 with an Alton
Works perfectly
It's 185 long 79wide 170 tall
Cheers

Thanks Baz, think I’ve sorted it, mine was an ETX, not EX and I measured wrong!,
