If your 12 volt battery is in good shape, then it's always charged while the car is recharging. If the battery shows less than about 11 volts, many computerized chargers won't recognize it as a 12 volt battery and will fail to recharge it - I keep an old $30 6 amp analog battery charger on my shelf just for that purpose . . . . it will recharge any battery no matter how low the voltage is
One thing proven here many times over is . . . . when your 12 volt battery is near the end of it's useful life, an iMiEV will exhibit all sorts of very unusual problems. The factory battery at about 7 years of age has been the culprit more times than I can count. If you have to jump start your iMiEV for any reason, problems are just around the corner and you should probably make a trip to the store for a new battery if you do successfully get it running.
I've never had those problems, but I've never attempted to go much beyond 5 years or so before I preemptively changed out my 12 volt batteries in all 3 cars. I don't care for weird surprises . . . . and more than that, I hate to walk!
