What are the reasons for the red battery warning light?

[PaisleeLynn]

The reasons for the red battery warning light are: 1. The battery itself has aging or power loss issues; 2. During the use of the battery, the battery terminals become loose or oxidized; 3. The generator belt or tensioner is too loose; 4. The generator voltage regulator or excitation circuit is faulty. The solutions for the red battery warning light are: 1. Replace the battery in time; 2. Clean or tighten the battery terminals; 3. Replace the belt or adjust the tensioner; 4. Inspect and replace the generator. The working principle of the battery is that during charging, external electrical energy is used to regenerate the internal active material, storing electrical energy as chemical energy. When discharging is needed, the chemical energy is converted back into electrical energy output.
