<div dir="ltr"><div class="gmail_default" style="font-size:small">The newer cars are highly dependent upon sensor reads for the various computers and can/will act differently than the older analogue cars with dying batteries. It sounds like your battery may have shorted plates, perhaps due to sulfation or other mechanical causes, for such an abrupt failure to occur. </div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">I am curious, though, as to why your car would not start when jumped from a running vehicle. If you have a voltmeter on the dash it would be interesting to see what it shows with the key on, and then when you had the jump going. If you do not have a dash voltmeter, an OBDII reader may be able to show it for you.</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">Good luck today with the battery replacement and you might wish to compare the voltage reading pre and post battery swaps.</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">best,</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">doug</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Jan 9, 2024 at 10:39 PM Dwade Reinsch <<a href="mailto:dreinsch@swbell.net">dreinsch@swbell.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div><div style="font-family:"Helvetica Neue",Helvetica,Arial,sans-serif;font-size:13px"><div></div>
<div dir="ltr">This afternoon I was sitting in the 2016 Honda Odyssey van waiting for granddaughter to finish a theater activity and I went to sleep in the front seat. Had the radio and inside lights on. When she finished and came out, car would not start. Completely dead. Electric seat would not come back to driving position, etc.</div><div dir="ltr"><br></div><div dir="ltr">Here's the question: In the old days a weak battery would give notice by cranking slowly, etc., before failing. This is the car I drive regularly and it gave NO warning. Luckily, I could call son-in-law and he came to help. Would not start with good set of booster cables. Would not start with 15 minutes of charging on cables before attempting to start. So in the morning I'll take pickup and tools and pull battery, get a replacement, and move the van home.</div><div dir="ltr"><br></div><div dir="ltr">Does anyone have a suggestion for identifying a failing battery before being stranded?
