I have now -- despite MRC tech support for the Super Brain -- charged both my Insight IMA batteries. The replacement IMA [post H-B-R] had half the miles [47K], high capacity, and in self-discharge seemed uniform to my *uninformed* standards. But about 6 weeks later its mileage sank from 70MPG to 57MPG. The State of Charge graph stays at FULL or one tick below since the recharge, and that must be trouble.
Today I have the Check Engine light altho no IMA light. Still this was a cheaper treatment as we are told. I must try with a grid charger.
