Voltage is the energy per unit charge. Thus a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other. The car battery can move more charge than the motorcycle battery, although both are 12V batteries.

What Are Batteries and How Do They Work? Batteries and similar devices accept, store, and release electricity on demand. Batteries use chemistry, in the form of chemical potential, to store energy, just like …
Electric Current. Electric current is defined to be the rate at which charge flows. A large current, such as that used to start a truck engine, moves a large amount of charge in a small time, whereas a small current, such as that used to operate a hand-held calculator, moves a small amount of charge over a long period of time.
The outer case and bottom form the positive electrode, typically made from manganese oxide, silver oxide, or copper oxide. Once, button batteries commonly used mercury oxide and graphite as the …
Amp-hours, or Ah for short, are a unit of measure for a battery''s energy capacity. This rating tells us how much current a battery can provide at a specific rate for a certain period. So, for example, if you have a fully-charged 5-Ah battery, it can provide five amps of current for one hour.
Lead-acid batteries work by storing energy in the form of lead sulfate (PbSO4) on the positive electrode (the anode) and lead metal on the negative electrode (the cathode). ... The amount of current in a battery depends on the type of battery, its size, and its age. A AA battery typically has about 2.5 amps of current, while a 9-volt battery ...
The lithium-ion (Li-ion) battery is the predominant commercial form of rechargeable battery, widely used in portable electronics and electrified transportation.

maximum capacity. A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps. Similarly, an E-rate describes the discharge power.
This type of battery would supply nearly unlimited energy if used in a smartphone, but would be rejected for this application because of its mass. Thus, no single battery is "best" and batteries are selected for a particular application, keeping things like the mass of the battery, its cost, reliability, and current capacity in mind.
