The higher the power, the quicker the rate at which a battery can do work—this relationship shows how voltage and current are both important for working out what a battery is suitable for. Capacity = the power of the battery as a function of time, which is used to describe the length of time a battery will be able to power a device.
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.
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).
Car battery output refers to the electrical energy produced by a car battery, measured in volts (V) and amp-hours (Ah). This output is crucial for starting the engine and powering electrical components in a vehicle.
This means that for a given voltage, increasing the amperage results in higher power output. For example, at 12 volts, a battery providing 50 amps results in 600 watts of power. Battery capacity is indirectly related to both voltage and amperage. It refers to how much energy a battery can store and is typically measured in amp-hours (Ah).
When I first got this unit, it threw this E21 message only a week or so after installation. Does so with nothing attached. CyberPower RMA''d the unit, and I had to beg them to also cover return shipping since the unit was basically problematic out of the box. Now, almost 2 years later, the replacement unit is doing the same thing.

(P_{out}) is the output power, (P_{in}) is the input power. Generally speaking, the higher the efficiency, the better. This implies less waste. In other words, if a system is 30% efficient, then 70% of the input power is wasted, whereas if a system is 99% efficient, then only 1% of the input power is wasted.

Applications that call for brief bursts of energy can benefit from the high power output that a battery with a high power density can deliver for a given size or weight. The nature of the characteristics that each density represents is where the main distinction between energy density and power density exists.
