I am wanting to understand how the 2 batteries work together- the one under my hood and the huge one in back.
I have the 2013 Energi and had the battery replaced under warranty about a year ago after car kept going completely dead. No problems until this past week.
The issues I had previously, my radio would stop turning on and 2 days later, my battery was dead even though I had been charging it every night. So fast forward.. . no issues since battery replacement until a few days ago, my radio would not come on. Car was on charger all night. 2 days later,
I came home & needed to charge car as battery at 0%. I couldn't plug it in it right away and ended up leaving it overnight. Next day, car was dead. I jumped it & thought it would be fine but when I got back into my car after disconnecting the jumper cables & parking the other car I used to jump, it was off & dead again & would not start. Ugh! So is that normal?
I ended up charging it again same way and left it for 30 minutes and it started & I was able to pull into my driveway where my charger is & plug it in. Started up fine this morning. I'm mainly just wondering if that's normal or not. A family member has the same car/ year and purchased a portable charger she keeps with her. I just purchased one for myself last night!
Hoping was happened was my own fault! Thanks in advance!
