One of my dads fast Alfa's was restored about 10 years ago. At that time dad was still working and he subcontracted some of the finishing work including some electrics.
This company installed a nice slim battery in a custom built case.
After 10 years this battery is slowly dying and my dad would like to buy an identical one. (at least sizewise).
Only it has no make stickers (any more) on it and the company cannot remember where they got it from...
Size (LxWxH) aprox: 245mm x 125mm x 190mm
Looking at the text it could be Italian but I'm not shure.
