Cultus have battery bracket on which battery sits.
Mine is 20 x 13 x 23 cm ( 200 x 130 x 230) w x dx h
so if u r choosing battery, check its dimension with these requirements:
Minimum 38 Ampere but if u have cng, deck, locking system etc. Plus age of your car so 50 Ampere is recommended one.
Be careful
AGS 50 does not mean 50 Ampere
AGS 60 doesn't mean 60 Ampere, they are just model number for looting simple people. Check their specification sheet for exact ampere and number of plates per cell.
CONCLUSION: Go for battery with 50 Ampere
No. Of plates: At least 11 (13 is preferable)
CCA: 300 A or above( Cold current ampere)
MAGIC EYE(Preferable) to check battery condition
Height should not be more than 230 mm (23 cm) otherwise bonnet body will touch battery terminals or battery body.
