Honda Civic Hybrid Battery

[wevelo]

I’ve never been able to determine how accurate the charge monitor is in my car, but my impression is that it isn’t particularly accurate. So I’m not sure that there is a significant difference between a one and two block fluctuation. In my case, I didn’t notice any change in IMA performance for years. About 6 months before the IMA battery failed I started noticing that the car was less responsive on acceleration and that the idle auto-stop feature didn’t operate as frequently. This was all corrected after the battery was replaced; the car now runs like new.
