Sulfation: The formation of lead sulfate crystals on the plates of a lead-acid battery. Normally used to
refer to large sulfate crystals, rather than small crystals formed in normal battery operation. The plates of
a battery will sulfate if left in a partially charged state, causing reduced battery capacity and shortening
the life of the battery. If caught in time, equalization will remove the buildup of sulfation.

Voltage: The electrical potential between two points. Voltage is analogous to water pressure in that it
pushes the electrons or current through a conductor. The unit for voltage is volt and designated by the
letter V.

Wet Acid or Flooded Batteries: The most common type of PV battery. Battery caps may be removed to
expose the electrolyte liquid inside the battery. Need proper ventilation due to gassing and may need to
be topped up with distilled water at regular intervals.
