Is Battery Size Measured in Volts or Amperes?
1 Answers
Capacity is measured in amperes. Ampere, also known as milliampere, is a unit of electric current, while volt is the unit of voltage, referred to as volt. Below is relevant information about batteries: 1. Battery: A battery, also known as a storage battery, is a device that converts chemical energy into electrical energy. The term 'battery' typically refers to lead-acid batteries, which are primarily made of lead and its oxides, with sulfuric acid solution as the electrolyte. The normal service life of a car battery ranges from 1 to 8 years, largely depending on the vehicle's usage conditions. 2. Battery Replacement: If the battery is dead, it is recommended to first measure the battery voltage. When using a multimeter for inspection, measure the battery voltage during engine cranking. You can initially use a high-frequency discharge machine or a battery tester for measurement. Under a load current of no less than 110 amperes, the minimum voltage should not be lower than 9.6 volts and should remain stable for 5 seconds. If the voltage is below 9.6 volts but can remain stable for 5 seconds, it indicates over-discharge, and the battery should be recharged promptly. If the voltage is below 9.6 volts and cannot remain stable for 5 seconds, rapidly dropping to 0 volts or close to 0 volts, it suggests a battery malfunction that may require replacement.
