Recharge it immediately, don't leave it charging all
week and top charge just before the flight.)


IMO, top charging does not help. Most of the articles I've read on the care
and feeding of batteries advocate taking the battery off charge at least 8
hours before use. That may not be practical for most of us since that would
mean taking the battery off around 4 in the morning if you'r planning on taking
off at noon.

What I've found works the best is a good state of the art charger tailored to
the chemistry of your specific battery. Different batteries have different
peak voltages, charge rates, etc.

The best charger I've found is the HPX10 charger manufactured by Xenotronix, on
the web at http://www.xenotronix.com/products/leadacid/hpx-10.htm. If your
model is not listed, contact them and they can tweak the specs to your battery.

With this charger, my battery has increased capacity and should last many
seasons.
