A unit of measurement for electron flow or current through an electrical circuit. (Amp = Volt / Ohm)
A unit of measurement for electron flow or current through an electrical circuit for a certain period of time. (Ampere X Hour = Ampere-Hour).
In a lead acid battery, it is a dilute solution of sulfuric acid (H2SO4) and water.
A tool used to measure the specific gravity of the electrolyte solution.
A unit of measurement for electrical resistance within an electrical circuit. ( Ohm = Volt / Ampere )
Expresses the relationship between voltage ( volts ), current ( amperes ), and resistance ( ohms ). (Ohms = Volts / Amperes).
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.
A method of wiring batteries together by connecting the positive terminal of the first battery to the positive terminal of the second and the negative terminal of the first to the negative of the second. The capacity for batteries connected in parallel becomes additive, while the voltage remains the same as the individual battery.
An energy storage device that can deliver energy but cannot be recharged.
An energy storage device that can deliver energy and can be recharged.
