What does 'Battery Low, Please Start the Vehicle' mean?

[LiamMarie]

Battery Low, Please Start the Vehicle means: The car's battery power is insufficient, and the engine needs to be started to recharge it. The reasons for low battery power are: 1. Insufficient power generation from the alternator; 2. Aging or damage to the battery, resulting in insufficient charge retention; 3. Low rated capacity of the battery; 4. The car has a power leakage or excessive sleep current; 5. Using electronic devices while parked; 6. Frequently driving short distances. The working principle of the battery is: It uses a lead-acid battery, operating on the primary cell principle, with the positive plate being lead oxide and the negative plate being pure lead. When the load is connected, the lead on the negative plate reacts with sulfuric acid to form lead sulfate and lose electrons, while the lead oxide on the positive plate reacts with sulfuric acid to form lead and water and gain electrons, thereby generating an electric current.
