Hi

I have a Yuasa 12V 40Ah 360A SMF Battery is there a good enough battery for a 2005 1.2 mk2b punto is the 40ah enough? many thanks

Would think so yes, unless you have a lot of aftermarket load fitted.
Our runs around quite happily on a 37Ah 330A.
The little bit extra will do no harm.
Keep all the connections clean and tight all the way back to the alternator.

Ive fitted a grande punto battery in mine.....
Much bigger then a standard mk2 punto

No issues

Except i got a tray from scrappy and cut it up..... as size wise they are different
