BCAA’s top tips for proper car battery care

Nothing puts a damper on your day, like going to start your car, only to find that you have a dead battery. It usually happens without warning and always throws a real wrench in your plans. Luckily, BCAA is here to save the day, whether it’s to provide a quick boost or even deliver you a brand-new battery. Yep, that’s BCAA’s Battery Service Program hard at work!

When it comes to keeping unpleasant surprises as bay, proper maintenance is always the best approach. Learn about what could be affecting your vehicle’s battery health and the steps you can take to keep it in good shape.

Factors that affect your vehicle’s battery health

  • Driving habits. Without regular driving, vehicle batteries can deteriorate over time. This is especially true for older batteries or feature-packed newer vehicles, and problems can start after just a few weeks of sitting parked.
  • Power-hungry gadgets. Even when a car is turned off, things like the clock, radio, and onboard computers continue to draw power from the battery. Over time, these drains will deplete the battery’s ability to start your car.
  • Extreme temperatures. As the temperature drops, so does your car battery power – at zero degrees Celsius, a vehicle’s battery loses about 35 percent of its strength. When it comes to weather, BCAA sees a spike in roadside assistance calls related to battery issues during really cold months (and really hot months as well).

Driving less? Tips to protect your vehicle

As we shift into winter, if you find yourself driving infrequently (hello work-from-home life), it's a good idea to give your vehicle's battery some extra care. The combination of cold weather and an idle vehicle can cause your battery to lose its charge. To help avoid this, consider these tips to keep your battery in good shape:

  • Drive every 3-4 days, and drive until the engine temperature reads ½ way on the gauge. This is the proper operating temperature for your vehicle.
  • Idling alone won’t work. Modern charging systems only give enough juice to keep the battery topped off enough to sufficiently run all the vehicle’s accessories. To get your battery to a fully charged state, you need to go for a drive.
  • Consider a battery maintainer to keep your battery charged while your car stays parked. Wired into your vehicle’s battery and plugged into the wall, battery maintainers can be ordered online to limit outings. Make sure you follow safe usage instructions.
  • Park your vehicle so that the battery is accessible in case you do need a boost.

Signs it might be time to replace your battery

When it comes to proper maintenance, the vehicle, the battery's health, and environmental conditions all play a role. On average, a battery will last 3 to 5 years, but driving habits and exposure to extreme elements can shorten its life. If your vehicle won’t start and you’re experiencing any of these symptoms, it might be time to replace your battery:

  • Lights look different. If your headlights are dim and appear yellow instead of white, your battery’s power may be declining. You might also notice that interior dome lights appear dim or flicker, and warning lights may display on the dashboard.
  • The car horn sounds strange. When your car horn sounds less emphatic than usual, your car battery could be on the fritz.
  • Electronic accessories fail. Signs your car battery is failing include your radio, heated seats, or cell phone charger not working as usual.
  • It doesn’t look or smell right. Sometimes, a simple visual inspection or smell test is all it takes to know your battery is in trouble. If you notice a sulfur or rotten egg smell, or your battery is swollen, cracked, or corroded, it may be time for a replacement.
