My old car battery (Exide Express) is totally dead. Now I am buying a new battery. I want to know which battery is the best battery for my car (diesel 2002 model). My car model is a Hyundai Accent diesel 2002 heater engine. I already Googled battery types. There are Exide Max, Exide Mattrix , and mine was an Exide Express. Can you please tell me the difference from this battery? My car self start drains more battery when self start. Please suggest a more powerful Exide battery which will work for me.
