As This keeps on coming up here is the biggest battery info to fit in a standard Mini Battery Box
Some use a 063 075 or a 096 which I understand is a very snug fit.
063
Capacity: 44 Ah CCA: 440 A Length: 212 mm Width: 175 mm Height inc. terms: 175 mm
075
Capacity: 60 Ah CCA: 540 A Length: 242 mm Width: 175 mm Height inc. terms: 175 mm
096
Capacity: 74 Ah CCA: 680 A Length: 278 mm Width: 175 mm Height inc. terms: 190 mm
These diamensions are for the Varta Blue range of batteries but other manufactures brands/numbers should be made to the same specification.
