Taiwwa Posted December 23, 2015 Report Share Posted December 23, 2015 My old car had this bad habit of dying. It would die if I listened to the radio with the engine off for ten minutes. Will a C-Max, by virtue of its hybrid design, suffer fewer dead batteries? Quote Link to comment Share on other sites More sharing options...
BIG ROCCO Posted December 24, 2015 Report Share Posted December 24, 2015 Actually, I think reliability of the 12V battery is one of the CMax's weak points - at least on early year models and more so on SE models. The unfortunate thing is that apparently, the HVB cannot be used to boost the 12V battery...unlike my 2012 Lacrosse. In the Lacrosse, my OE 12V battery died this past Summer, but there is some self boost mode in which the HVB is used to charge the 12V battery enough in 15-20 seconds to permit the engine to start, and it worked PERFECTLY! It's strange that, overall, the C-Max is a much more advanced hybrid system and more advanced car overall than the Lacrosse, but there are some things that seem more backward - for example, no oil life % readout (although it is monitored/measured), no tire pressure readout (although it is monitored/measured) Quote Link to comment Share on other sites More sharing options...
Bill-N Posted December 24, 2015 Report Share Posted December 24, 2015 Alas, there is no (known) way for the high-voltage battery to recharge a dead 12V battery. Quote Link to comment Share on other sites More sharing options...
