2. Check Your Battery For Corrosion
Corrosion on your car’s battery could indicate a power problem as well as lead to other serious problems if the acid begins leaking onto other components. Over time, that corrosion, caused when acid within the battery releases hydrogen gas, might interfere with the battery terminals’ ability to transfer power. The battery has to work harder to compensate, and that extra work can shorten its life.
You can clean the battery terminals (carefully!) with household items like baking soda and an old toothbrush. If your battery has been suffering from corrosion for a long time, however, the damage may be irreversible. In that case, it’s time to replace.
