I will look into those batteries thanks. It’s been a pending issue, I noticed a slow decrease in mpg at first, but it was hard to diagnose how drastic with a change to my wheel/tire/intake set up, then it became more noticeable and the battery would frequently and rapidly charge and discharge on even short trips. The last week, it was making the car pretty undrivable with the lack of torque when I needed it. I intend to keep the car for a long time so I am going to replace the battery. As far as when the code popped up, I would say that was maybe two months ago and reaching out to some people it seemed like it may have just been a software issue, which I know Honda issued an update for. On my own personal faults, I dismissed it as that but started to suspect something else. I am curious to know if replacing the battery is something I can do myself or not.
