Tips to Extend the Lifespan of Your Car Battery

An unexpected flat battery can be a big inconvenience. Here’s how to keep yours in good condition for longer.

Don't Leave Your Car Unused for Long Periods

If your car sits inactive for days or only takes short trips, the battery doesn’t get enough time to recharge. Your car performs best when used regularly, so try to take it out for a 30-minute drive at least once a week to warm up the engine and circulate fluids. If your car is unused for over two weeks, ensure the battery is fully charged. Consider investing in a battery maintainer or trickle charger to keep the battery at an optimal charge level during long periods of inactivity. Contact Battery Central Roadside or your local automotive workshop for advice when in doubt.

Clean Your Battery Regularly

Grime, dirt, and dampness on a car battery can cause leakage, leading to a flat battery. Clean the surface grime monthly with a sponge and dry cloth. Corrosion on battery terminals and lead clamps is common and can hinder electricity flow. Ask your mechanic to clean the terminals during servicing if needed. Regular cleaning prevents corrosion and ensures your battery remains in good working condition. If you notice significant build-up or damage, it may be time to replace the battery.

Avoid Using Electronic Accessories When the Engine Isn't Running

Electrical loads like headlights or interior lights or running the radio without starting the engine can drain the battery. When the engine is off, the alternator is shut down, so electronic accessories draw power directly from the battery. To avoid this, develop the habit of turning off all lights and electronics before exiting your car. Additionally, always lock your car to ensure the computer system isn’t draining the battery unknowingly. Remember, modern cars have complex electrical systems that continue to draw power even when the vehicle is off, so minimizing this drain is crucial.

Check Your Battery's Voltage Regularly

Regularly checking your battery’s voltage can help you monitor its health. A fully charged car battery should have a voltage of around 12.6 to 12.8 volts. If the voltage drops below 12.4 volts, recharging the battery is time. You can use a multimeter to check the voltage or have it checked during routine maintenance. Early detection of a low charge can prevent unexpected battery failures.

Ensure Proper Installation and Secure Connections

A poorly installed battery can lead to numerous issues, including vibrations that can cause damage to the battery plates. Ensure your battery is securely fastened in its tray and the connections are tight and corrosion-free. Loose or corroded connections can result in poor electrical contact and battery drain. During regular maintenance, ask your mechanic to inspect the battery installation and connections to ensure everything is in good working order.
