What is battery power?
The battery power is the amount of electrical energy stored in the battery. Mobile devices are powered by rechargeable lithium-ion (Li-ion) or lithium polymer (Li-poly) batteries. The power capacity of the battery has a direct impact on the usage time.
What is the relationship between power and battery capacity?
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.
How much power can a battery draw?
However, the amount of current we can really draw (the power capability) from a battery is often limited. For example, a coin cell that is rated for 1 Ah can't actually provide 1 Amp of current for an hour, in fact it cant even provide 0.1 Amp without overextending itself.
What is battery power capacity?
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).
How do you calculate power capacity of a battery?
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.
What are battery basics?
Understanding battery basics, including chemistry, voltage, and capacity, is essential for anyone using electronic devices or electric vehicles. Battery capacity indicates how much energy a battery can store, while voltage determines the power output.
What Are Number 5 Batteries? Explained!

Electric battery
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. [2] The terminal marked negative is the source of electrons.
Battery Capacity Calculator
As you might remember from our article on Ohm''s law, the power P of an electrical device is equal to voltage V multiplied by current I: As energy E is power P multiplied by time T, all we have to do to find the energy stored in a battery is to multiply both sides of the equation by time:

Battery Arrangement and Power
Batteries are rated in amp-hours, or, in the case of smaller household batteries, milliamp-hours (mAH). A typical household cell rated at 500 milliamp-hours should be able to supply 500 milliamps of current to the load for one hour. You can slice and dice the milliamp-hour rating in lots of different ways.
