Sulphation occurs fastest when the battery is deeply discharged, but occurs
under normal use as well, just more slowly.
One option, given that you can't plug in a charger when you're parked for
long periods, would be to add an onboard desulphation unit that works while
driving. I don't know how many manufacturers make them - the only one with
which I'm familiar is the one from BatteryMinder.
And really, I have no interest in the company other than satisfaction with
their products and their service. For instance, I absolutely killed a brand
new recombinant gas airplane battery by leaving the master switch on for 5
days. The solenoid drained the battery absolutely flat, I couldn't get it
to take any charge, and the battery manufacturer was pretty sure I could
never reclaim the battery. Note to EE's - yes, I did try a plain,
non-computer charger at first because computer chargers won't charge a
battery that doesn't have high enough voltage.
Not wanting to replace a new $200 battery without trying something, I called
BatteryMinder and talked with their head tech guy. He told me how to
properly recharge and condition the battery, and even called me back a
couple of days later to see how it was coming along. 2 years later it's
still fine.

Well that brings up a new tack--I'm about to buy two new batteries for the
truck and I'd like them to last. Is this sulphating an issue that comes
from sitting or being charged on a charger, or...?
