5 tips for Bike Car and Truck Battery Maintenance Tips Regularly inspect the battery for dirty terminals – any leak or corrosion is a sign that the battery is not working properly. Keeping the battery terminal clean can increase the life of the battery. Warm weather has a negative impact on the battery – as much as possible ,park your car or bike away from the sun. Leaving the lights or any other electrical appliance like Air conditioner or music system in your car even when the ignition is switched off is not correct. The battery will be consumed in some proportion if the appliance is not switched off. A securely placed battery is a safe battery. A loosely place battery can damage other car parts and even fall off the battery holder.Excessive vibration can result in damaging the battery. If the battery has plugs which can be opened for refilling the battery with distilled water then make sure they are properly plugged and closed at all times.
