Yes it will help to grid charge your car IMA battery.Mine have 125k miles. Ima light is ON(only on highway), but still asist and recharge. In city IMA light is OFF and if I'm driving below 22 mph is runing full electric(mpg indicator showing 0). I have error code P0A7F. Dou you think a grid charger like Max Volts, Hybrid Automotive Prolong™ Battery Reconditioning Package or other products like this one will help ?
Thank you !
