Mine is over 7 yrs old and still works ok but sometimes when its cold I get slow crankings, also battery yellow icon displays on dash if listening to radio a minute after you turn off engine. I recently found out that your REST residual heat stops working along with rear window defroster. (ECU does this to save all the power possible to be able to start)
I believe the fact that helped my battery last all these years its due to I drive 90% freeway at high rpms and always charges battery at the fullest. Weather also helps since here in San Diego CA, tempetures dont go below 50F usually. Also very important, always in parked in garage and kind of warm. I ll be on the lookout for a new battery soon as dont I dont think I ll make it through another winter.
