Can a car battery still be used after sitting for 6 months?
1 Answers
A car battery cannot be used after sitting for 6 months due to internal sulfation and passivation. Precautions for battery storage: Keep away from metal objects; Do not store in damp places; Do not store in extremely cold locations; Do not store in high-temperature areas; Recharge the battery every month. Methods to determine the condition of a car battery: Over 80% of maintenance-free batteries currently have a charge indicator window. The colors visible in the observation window are generally divided into three types: green, black, and white. Green indicates sufficient charge, black indicates slight discharge, and white means the battery is dead and needs replacement. Refer to the label on the battery for specific details. Observe whether there are white or green powdery substances around the battery terminals. These are battery oxides. High-quality or new batteries generally do not easily develop these oxides. Once they appear, it means the battery's performance is starting to deteriorate.
