When electrolyte fluid from inside the battery leaks to the battery's outer surface. Explaining battery terminology.
Since this is a particularly confusing part of measuring batteries, I'm going to discuss it more in detail. Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh).
Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh). A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) the battery can provide for some amount of time (generally in hours). Voltage * Amps * hours = Wh.
You are very quick to judge. "Typical measure for the power-to-energy ratio is C or P-rate... C-rate refers to battery's rate in constant current charge/discharge rate vs. its capacity whereas P-rate, a term commonly used by battery manufacturers, is the battery's rate in constant power charge/discharge rate vs. its capacity.
Energy or Nominal Energy (Wh (for a specific C-rate)) – The “energy capacity” of the battery, the total Watt-hours available when the battery is discharged at a certain discharge current (specified as a C-rate) from 100 percent state-of-charge to the cut-off voltage.
