OPERATION AND SERVICE INFORMATION
open circuit has a broken path.
7. Cycle——One discharge of a battery plus one recharge.
8. Depth of Discharge (DOD)——The percentage of capacity actually removed from a battery compared to
the total rated capacity.
9. Electrolyte——In a deep cycle battery, it is a dilute solution of sulfuric acid and water.
10. Hydrometer——A tool used to measure the specific gravity of the electrolyte solution.
11. Equalization——An overcharge performed on flooded lead-acid batteries after they have been fully
charged. This maintenance step helps eliminate stratification and sulfation.
12. Ohm (?——A unit of measurement for electrical resistance within a circuit.
13. Open Circuit Voltage——The voltage of a battery when there is no load attached(not receiving or
delivering energy).This measurement is best taken when the battery has been at rest for at least 6 hours.
14. Power Inverter——An electronic device that converts direct current (DC) power from a battery into
standard alternating current(AC)house power.
15. Primary Battery——An energy storage device that can deliver energy but cannot be recharged (i.e.,
disposable flashlight battery)
16. Secondary Battery——An energy storage device than can deliver energy and can be recharged.(i.e.,
automotive or deep cycle battery)
17. Separator——A divider made of porous material that is placed between the positive and negative plates
in a battery cell and allows current to flow through it, while preventing direct contact between the plates
which would cause a short circuit.
18. Specific Gravity(S.G.)——A measurement of the strength of battery electrolyte by comparing its
density to that of pure water.
19. Stratification——A condition where the concentration of acid is greater at the bottom of the battery that
at the top.
20. Sulfation ——The formation of lead sulfate on the positive and negative electrodes.
21. Volt (V)——A unit of measurement for electrical potential within a circuit.
22. Watt (W)——A unit of measurement for electrical power.
23. Watt Hout (Wh)——A unit of measurement for electrical power for a certain period of time.
