Glossary of Terms
• Maintain a battery
BatteryMINDer ensures batteries are truly fully charged and will likely
continue improving the condition of the battery to the fullest extent
possible.
• Rested
A battery that has been as fully charged as possible and left disconnected
from charger or any type load overnight.
• Specific Gravity
One of the key parameters of battery operation is the specific gravity of the
electrolyte. Specific gravity is the ratio of the weight of a solution to the
weight of an equal volume of water at a specified temperature. Specific
gravity is used as an indicator of the state of charge of a cell or battery.
• Sulfation
Occurs when the battery sits for long periods of time and the electrolyte
solution begins to break down. Sulfur in the solution leaches from the
electrolyte, sticking to the lead plates as converted lead sulfuric crystals.
