* If your car won't start after replacing the battery, check the connections and make sure they're secure. * If you notice any corrosion or wear on the battery terminals, clean them with a wire brush and apply a small amount of petroleum jelly. * If your car has a faulty alternator, it may not charge the new battery properly.Conclusion
