Does a car display many question marks when the battery is almost dead?

[OEloise]

A car does not display many question marks when the battery is almost dead; instead, many warning lights will illuminate. Below is an introduction to battery-related information: 1. Charging method: Use constant voltage with current limiting for charging. 2. Duration: Charge at a constant voltage of 14.8V with a current limit of 15A for 16 hours, followed by a constant current of 3A for 4 hours, totaling 20 hours. Below are extended details about battery charging voltage and current: 1. Voltage: The charging voltage for motorcycles is 12V. During charging, the voltage typically ranges between 13.5-14.5V. When charged on the vehicle via the rectifier, it does not exceed 15V. If using a charger, the charging voltage is generally 14V. 2. Current: During the charging process for motorcycles, the charging current should not be too high. It is recommended that car owners avoid using fast charging. When charging, use half of the rated charging current and double the rated charging time.
