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 discharged for a long period of time and large
sulfate crystals build up in the plates. The large sulfate crystals increase
the resistance of the plates and makes the battery harder to recharge.
