For lead-acid batteries, a 100ah battery typically contains six cells, each with 11 to 15 plates, depending on the battery''s size. This means a 100ah lead-acid battery can have anywhere from 66 to 90 plates. For lithium-ion batteries, the number of plates is not relevant, as they do not use plates in the same way as lead-acid batteries.
For example, if a battery has a capacity of 10 Ah, it can deliver 10 amps of current for one hour, or 5 amps for two hours. Watt-hours (Wh) measure the total amount of energy that a battery can deliver in one hour. This unit takes into account the voltage of the battery as well as the current. ... For example, if a lead-acid battery has a ...
For lead-acid batteries, the deeper a battery is discharged, the lower its capacity and run time will be. It''s recommended not to discharge them more than 50% to maximize your battery''s life. If you frequently discharge a lead-acid battery to 80%, it will very likely have reduced capacity after one season.
A normal Lead-Acid battery when fully charged has something like 2.1 V/cell. How this translates to Ah depends on the shape of the discharge curve. If we simplify and assumed a linear drop in voltage over time (far from reality), the average voltage would be (2.1+1.67)/2 = 1.89 V. 21 W at 1.89V implies 11.14 A. 11.14A for 1/4 hour is 2.78 Ah.
