I suggest that you just buy a moderately priced local battery. AC Delco is the original equipment and parts supplier for GM (it is a GM subsidy). And we all know how great GM's reliability record is.

I just use a Motolite Enforcer battery. Yung ginagamit ng mga delivery truck at schoolbus. They do last more than two years naman despite me driving with the headlamps on and having an amplifier-powered sound system.

And yes, may traffic sa States. Na-traffic na ko dun. At mas mainit pa sa Pinas ang summer (no wonder may mga namamatay sa heat wave).
