Your vehicle’s battery is one of its most important yet overlooked components. A dead battery leaves you stranded and dealing with an inconvenient no-start situation. Taking some simple preventative steps goes a long way toward maximizing battery life and avoiding annoying battery issues down the road.
Clean Battery Terminals Regularly
Over time, the metal battery terminals can develop a coating of corrosion from hydrogen gas released by the battery’s internal chemical reactions. This crusty buildup acts as an insulator, preventing proper flow of electrical current needed to start your vehicle.
Use an old toothbrush or battery terminal cleaning tool dipped in a baking soda/water solution to gently scrub away any white or bluish corrosive deposits on the positive and negative terminals. Wipe everything clean and dry before reinstalling the cables for good connection.
Check for Tight Cable Connections
While you are cleaning the terminals, inspect the positive and negative cable connectors to ensure they fit tightly with no excessive wiggle room. Loose connections create resistance that can completely drain your battery’s power when attempting to start your car.
Use pliers to slightly bend the connector’s metal prongs inward if needed for a snug fit on the terminal posts. You may need to replace any severely corroded or damaged battery cables as well.
Limit Electrical Draw When Parked
Even when your vehicle isn’t running, accessories like internal clocks, security systems, and radio presets slowly drain the battery over time. This passive electrical load eventually leaves you with a battery too weak to start the car.
Before leaving your vehicle for more than a few days, locate the interior trunk release and other electrical accessory switches/fuses and turn them off to reduce battery drain. You can also use the battery disconnect switch if your vehicle has this feature.
Consider a Battery Maintainer or Trickle Charger
For vehicles that may sit for weeks or longer periods, your battery’s charge will inevitably get depleted without a running engine to recharge it from the alternator. The people at Clore Automotive advise that using a battery maintainer 12 volt solves this issue.
These smart chargers connect to a household outlet and constantly monitor and maintain your battery at its optimal level without overcharging. The maintainer provides just enough amperage flow to offset the self-discharge that all lead-acid batteries experience when not in use.
Follow Proper Jump-Starting Procedures
If your battery ends up completely dead, you will need to use jumper cables or a portable jump-starter pack to revive it with a boost of power from another energy source. Always be cautious and follow the proper order when connecting and disconnecting the cables.
Start by connecting the positive (red) cable to the dead battery’s positive terminal, then the negative (black) cable to an unpainted metal ground on the vehicle body or engine block, not the negative terminal itself. This routing prevents sparks near the battery that could ignite hydrogen gas.
Test Battery Regularly
Using a simple battery load tester gives you the most accurate reading of your battery’s true charge and cranking capability when you start your vehicle. The tester applies a momentary load, simulating the high current draw of the starter motor trying to turn over the engine.
If your battery voltage plunges below acceptable levels when put under this load, it is too weak and needs replacing. Catch a failing battery early before it leaves you without a started vehicle.
Conclusion
Following these simple preventative maintenance tips will maximize the lifespan and performance of your vehicle’s battery. A little proactive care beats dealing with the hassles and potential safety risks of an unexpected dead battery situation.
