  2. 2013 Happy with my battery after 7-ish years

    Generation 1 Volt (2011-2015)
    The last two mornings that I've started up my 2013 Volt, the Guess-O-Meter has predicted 46 miles! I only have 58,000 miles on the odometer, of which 68% are electric (it would be about 99%, except for a number of road trips to see my son in Chicago). I think the 46-mile prediction suggests...

  6. Happy 4th to You, and a question about jumping (i.e., battery)

    Generation 1 Volt (2011-2015)
    First of all, a happy Independence Day to all of you. We're having friends and family over to grill burgers on the deck and to swim in the pool, except that it's going to storm, and we'll all be squeezed inside the house instead. Anyway. A few days ago I took my jumper cables out of my Volt...

  12. Expected Volt Battery Life

    Generation 2 Volt (2016-2020)
    With GM’s decision to discontinue the Volt I had a couple questions for the forum relative to the expected battery life of a Volt. I usually keep my cars 10-15 years and have been averaging about 7k miles a year on my Volt in the two years I have owned it. So based on that it would take me...
  13. Cold Weather Battery Drop-Off

    Generation 2 Volt (2016-2020)
    Nine months of ownership for my 2018. When the weather was warm, my electric range after charging said 63-65 miles. Now the weather is cold (30s and 40s) and it's dropped to 45 miles. I expected a drop-off but that seems pretty big. Is that normal? Thanks, all.

    Anyone know what the acceptable variation in the cell voltages is suppose to be. Mine varies between 0.2 fully charged to 0.5 volts discharged. The dealer says that is normal. I don't believe him. This all started after my stator bearing was replace (loud whining noise).

  18. When do you charge it?

    Newcomers to GM-VOLT.COM (See here for FAQs)
    Seems like a basic question but I am getting conflicting answers. Bought a 2018 Volt LT about 3 weeks ago and want to make sure the main battery lasts as long as possible. I didn't see anywhere in the manual if it is okay to charge the battery at any time or only when completely dead. I...
