A battery with a bad cell may not jumpstart well. A dead battery lacks residual charge and can drain the other cells. If it retains some charge, jumpstarting might work temporarily. However, it’s usually best to replace the battery for better performance and battery health in the long run.
When attempting to jump a battery with a suspected bad cell, it is crucial first to check the connections and cables for any damage or corrosion. Ensure the jumper cables are attached securely. If the battery shows some signs of life but struggles to hold a charge, it may respond temporarily to a jump start. However, if the battery fails to start the vehicle or exhibits erratic behavior, it is wise to consider a replacement.
Troubleshooting involves testing the battery’s voltage with a multimeter. A significant voltage drop from the expected level may indicate a bad cell. Ultimately, while jumping a battery with a bad cell can provide a temporary solution, long-term reliability requires addressing the underlying issue.
Next, we will explore the process of evaluating battery health and understanding whether a replacement is necessary.
