You know that sinking feeling when you turn your key in the ignition, and instead of the roar of the engine, all you hear is a sad, defeated gurgle?

That’s a dead car battery, and it’s enough to ruin anyone’s day.

I should know. I own a vintage 2000 XJL-V8 luxury Jaguar vintage touring sedan; electrical gremlins are the norm. So, routine battery maintenance and regular battery checks will significantly lower your risk for the battery blues.

How it works

As you probably already know, the car battery is the essential component that starts your vehicle’s engine. Within the battery, a chemical reaction creates an electrical charge, which subsequently starts the car’s motor. Battery power is also required for your car’s electrical components like cabin and headlights.

Healthy Battery

Your battery is in the clear if it is consistently working, and clean. Your battery and its cables should be cleaned on a monthly basis with a small, stiff brush like a toothbrush to clear out dirt and debris from the road. Never use any sort of cleanser when cleaning. Healthy batteries should also be clear of corrosion. Brush away the corrosion from battery terminals by dipping a toothbrush into flat dark soda, or a mixture of water and baking soda, before scrubbing. Apply petroleum jelly on the surface after cleaning to prevent future build-up.

Unhealthy Battery

If your battery is displaying any of these symptoms, it’s time for a check-up. So, I asked my dealer and received these tips:

  • Low water in the battery cell could be affecting battery performance. Check the indicator on the side of the battery for the water level. If it needs filling, stop by our service department for a special tool to fill it up.
  • Age is a huge factor in battery health. Batteries are designed to last about five years, but this lifespan could shorten based on use and maintenance habits. If your battery is five or older, consider getting it checked out.
  • Cracks in the battery’s plastic casing or other wear on the battery connections could mean damage and are worth a second look.
  • Loose tie straps need adjusting. Make sure your battery is tightly secured, because engine vibration could knock the battery around and cause damage.

Assessment

Of course, the biggest sign of an unhealthy battery is a dead one, but it’s much better to routinely maintain your battery than to be left in a lurch without power. Get peace of mind with a power-up at your service department; or DIY.

    Winter battery charging – keep it connected

    I take my XKR “off the road” for the 6 months from October to April.
    I always hook the battery up to a CETEK charger on the winter setting.
    She always starts right up.
