VW dealers have solar chargers from VW, that plug into the ALDL to keep the batteries charged in the cars, while they're sitting on the lot, or at least they're suppose to. They left one in the trunk of a TDI I bought. I keep it in the Volt when I know it's going to sit for a bit 'cause a Volt tech told me that once the traction battery is charged, the DC to DC converter no longer charges the 12V battery. I also have a Schumacher AGM charger to keep the batteries up to snuff.

I had to change the 12V because the decided to not move in D. Put in a new Delco AGM and it was like nothing happened.
