how do i add sulfuric acid to the battery, acid first or water first?
Hello, thank you for your inquiry. Please dont add any acid to your battery, only distilled water. When your battery's electrolyte is observed to be low, filling the battery with water will keep the battery healthy and safe for use.
Ampere (A)
A unit of measurement for electron flow or current through an electrical circuit. (Amp = Volt / Ohm)
Ampere-Hour (AH)
A unit of measurement for electron flow or current through an electrical circuit for a certain period of time. (Ampere X Hour = Ampere-Hour).
Electrolyte
In a lead acid battery, it is a dilute solution of sulfuric acid (H2SO4) and water.
Hydrometer
A tool used to measure the specific gravity of the electrolyte solution.
Ohm (Ω)
A unit of measurement for electrical resistance within an electrical circuit. ( Ohm = Volt / Ampere )
Ohm's Law
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.
