There are also plans on the Internet for a DIY desulphator that would work
either parked or driving.  It draws energy from the battery at 12v, then
makes a high voltage spike to feed back into the battery.  One of those
combined with a solar panel should work well.

Google for "desulfator plans" (without the quotes).

Here's another commercial version I found:
