Charging your battery!

There are basically two kinds of chargers, linear chargers and switch mode chargers. The linear chargers are very cheap, and very stupid. They will use a constant charging voltage and current. The switch mode chargers are more sophisticated, and will adjust the current as the state of charge of the battery changes.

When charging with a linear charger, it's important to watch the progress, and stop charging before the battery starts to boil. The boiling causes water loss, and if you do not have an open battery, the water cannot be replaced.

The switch mode charger will take care of this for you. Some switch mode chargers include a number of charging steps, that will also help you solve common problems with your battery. The smartest battery charger in the world from CTEK has a desulphating step, that actually use a patented system of periodically boiling the battery, to reduce sulphation.
