Hey Eli I am in Springfield Oregon , I just purchased a 2000 insight with 212k on the original battery. I have the p1449 code coming up and I think it's a cell and not the whole battery over heating. I reset the post code and pushed the throttle getting on the freeway and the code appeared. However if I cruise the roads and don't push the light stays off. So are you able to help me decide what to do , I mean if it's really an original should I just get a rebuilt or new one and be done with it? I could pull the battery and learn to replace and balance the battery pack but is that what works, or the grid charger balancer system?
