Have Hankook in my company car (just handed over and checked if fluids are OK). Papers show it's installed since 2005 (around 148,000 km) on it!! (Well this sounds too good to be true to me too).
Also, buy the one which weighs more. Generally battery amps and life are directly related to plate weight.
Also, when wet battery fails the symptoms are usually ignored, so no prob, you will always push-start and go to buy new battery.
Also, local battery makers are lessening plate weight (that's why warrantee is lesser), you can notice how a 145 Ah battery of 2004 weighs twice that of the one available now, the sealed battery will be imported, and will weigh more.
