TL;DR: The alternator charges the battery as fast as the battery will let it, or as fast as the alternator can, whichever is lower, at a constant voltage (usually 13.8v, or 14.2v). The terminal voltage going down to 13.1v suggests the battery is not charging, and may be discharging, unless the battery is very low. The alternator or the battery ...
Voltage is measured in volts (V), with most household batteries ranging from 1.5 volts (like AA batteries) to 12 volts (like car batteries). The voltage of a battery is determined by its chemical composition. For instance, alkaline batteries, commonly used in household devices, typically have a voltage of 1.5 volts. Voltage and Battery Performance
When it comes to understanding how many amps a 9-volt battery has, it is important to have a basic understanding of the battery itself. Voltage, measured in volts (V), is the measure of the "force" of electricity or the potential energy difference per unit of charge. Amps, measured in amperes (A), is the measure of the amount of electrical ...
A 1.5 battery is no good at a voltage of about 1.35 volts. Alkaline batteries have a typical voltage of 1.5 volts, so at a lower voltage than that, the battery is no longer providing enough power to operate the device it''s powering. How to choose the right battery for your needs?
