My car came with what seems to be a cheap battery (battery pros brand). I'm having no troubles with my electrical system and the battery is less than 2 years old (manufacture date DEC 09). Would their be any benefit in swapping it out with a new OEM battery?

 

Not really. As long as cranking amps and voltage are good, I'd use it for at least a couple more years.

OT: Got any pics of the Lexus in your sig?

 

no

 

no, unless you're upgrading your sound system with some power. save the money and buy some mods

 

The fiber mat designs (Optima, etc.) are expensive but do have one notable advantage... they do not have open vents that can and do leak acid during high gee conditions. My cheap battery seeps enough that I have to pull it every year to clean to avoid corrosion.
