Battery life

Hi Fellas. In the shop we used to reacon on up to 5 years from new with factory battery then 3 years with aftermarket batteries after that. Nowadays with the higher electrical loads in vehicles and larger alternators, batteries tend to open circuit more than slowly die. If you get one dozy start after around 3 years and cant think of a good cause for it, fit a new battery and thank the gods that you didnt get let down out in the scrub somewhere. Cheers.
