u/Aggravating-Day-2864

Is it time to change my battery as it's been in since new. Couple year ago was flat after winter standing couple month, no issues since.

This morning only 3v in it. Been standing 2 days in lane. Got it jumped and drive out to charge.

Looking at Kia owners and they reckon batteries only last 5-7 year then require changing, have I been lucky?

Due for service and MOT soon so should I also replace the battery?
