How to Determine the Performance of a Battery?

[LeCalvin]

By checking the voltage and current during startup, you can accurately assess the condition of the battery. Here is some relevant information: 1. A battery (Storage-Battery) is a device that directly converts chemical energy into electrical energy. It is designed to be rechargeable, achieving recharging through reversible chemical reactions, typically referring to lead-acid batteries, which are a type of secondary battery. 2. Its working principle: During charging, external electrical energy is used to regenerate the internal active materials, storing electrical energy as chemical energy. When discharging is needed, the chemical energy is converted back into electrical energy for output, such as the commonly used mobile phone batteries in daily life.
