It's quite bulky than the previous batteries I bought though, I am myself surprised, but I didn't weigh it actually. And I didn't put this battery in my city idsi , actually bought it for my brother in law's pkdm swift 1300cc.
And In my my little technical knowledge , I think the OEM recommended AH rating should be installed in your vehicle, because alternator will be burdened for constantly topping up of over sized AH rating battery
