Can You Still Drive When the Car Battery Light Is On?

[DeKate]

When the car battery light is on, you should not continue driving as it may lead to over-discharging. The hazards of over-discharging include the formation of large lead sulfate crystals inside the battery, which are difficult to convert back during charging, resulting in charging difficulties and affecting the battery's capacity recovery. In such cases, the battery should be charged promptly, followed by three deep charge and discharge cycles, which can generally restore the battery. The car battery is an essential part of the vehicle and can be categorized into traditional lead-acid batteries and maintenance-free batteries. Since maintenance-free batteries use lead-calcium alloy grids, they produce less water decomposition during charging and have lower water evaporation. Additionally, their sealed structure releases minimal sulfuric acid gas, offering advantages such as no need to add any liquid and longer charge retention compared to traditional batteries.
