Power Capacity and Power Capability | All About Batteries

The way the power capability is measured is in C''s.A C is the Amp-hour capacity divided by 1 hour. So the C of a 2Ah battery is 2A.The amount of current a battery ''likes'' to have drawn from it is measured in C.The higher the C the more current you can draw from the battery without exhausting it prematurely. Lead acid batteries can have very high C values (10C or …

Battery SOC: How Do We Estimate "State Of Charge" Of Batteries?

A lead acid battery. It involves using a sensor that measures changes in the weight of the active chemicals present in the battery as it discharges. As the charge stored in the battery is used up, the concentration of sulfuric acid (an active electrolyte in the battery) decreases, which proportionately reduces the specific gravity of the solution.
