How long does it take to fully charge a car battery that has no power?

Taking a 12V60Ah battery as an example, the charging method adopts constant voltage and current limiting for charging, with a constant voltage of 14.8V and a current limit of 15A for 16 hours. Below is an introduction to the battery: 1. Working principle: The battery, also known as a storage battery, is a type of cell that works by converting chemical energy into electrical energy. Typically, the battery people refer to is a lead-acid battery, which is mainly made of lead and its oxides, with sulfuric acid solution as the electrolyte. 2. Maintenance method: Avoid storing the battery in a discharged state. A discharged state means the battery is not charged in time after use, which can easily lead to sulfation. Lead sulfate crystals adhere to the plates, blocking ion channels, resulting in insufficient charging and reduced battery capacity. The longer the battery remains idle in a discharged state, the more severe the damage. When the battery is not in use, it should be charged once a month to extend its service life.
