Karma won't hold a charge
I didn't drive my Karma for about three weeks and forgot to put it on a battery tender. Now when I jump it, it works fine, but as soon as I shut it down it won't restart. I have let the car run for a couple of hours and have driven it for 20 miles or more after jumping it, and it still dies as soon as I shut it off. Is this a simple case of a dead battery? Thanks in advance.
