Is the Sylphy's battery maintenance-free?
1 Answers
The Sylphy's battery is maintenance-free. A battery is a device that directly converts chemical energy into electrical energy. It is designed to be rechargeable through reversible chemical reactions, typically referring to lead-acid batteries, which are a type of secondary battery. The working principle of a battery is to use external electrical energy to regenerate the internal active materials during charging, storing electrical energy as chemical energy, and then converting the chemical energy back into electrical energy output when discharging is needed. The methods to test a battery are: 1. Inspect the battery's exterior; 2. Measure the battery voltage; 3. Check if the battery has lost water or turned black.
