Signs Your Battery Needs Attention

It’s a common misconception that a car battery will give you plenty of warning before it fails. In reality, especially in Colorado's climate, a battery can work perfectly one day and be completely dead the next. 

This can leave you stranded at the worst possible time. It's crucial to pay attention to the small, subtle signs that your battery is getting weak before it fails.

Here are the most common ways to tell that your battery is about to go out:

  • Slower Engine Crank: The engine sounds sluggish and takes longer than usual to turn over, especially on cold Longmont mornings.
  • Clicking Noise: You hear a rapid "clicking" sound when you turn the key, which means there isn't enough power to engage the starter.
  • Dim Lights & Electrical Issues: Your headlights and interior lights are dim, especially at startup, or your power windows move slowly.
  • Dashboard Warning Light: The red battery warning light is on, signaling a problem with the battery or charging system.
  • Battery Age: The battery lifespan is often only 3-5 years in Colorado. If your battery is in that range, it's time to have it tested.

Any of these symptoms is your vehicle's way of telling you the battery is on its last legs. Don't wait to get stranded. If you've noticed any of these issues, it's the perfect time to bring your vehicle in for a professional battery diagnostic service. We can quickly determine its true health and let you know exactly how much life it has left.

Frequently Asked Questions


How long does car battery installation usually take?

Most battery installations take under an hour. The exact timing depends on your vehicle’s design and whether we perform additional system checks.

Will I need to replace my battery if my car struggles to start?

Just bring your vehicle and any service records you might have. Our team will guide you through every step of the visit and answer questions along the way.

Does the Colorado climate affect battery life?

Yes. Cold winters and hot summers in Longmont can reduce battery lifespan. We select batteries designed for these ranges, improving long-term reliability for local drivers.

FAQs

  • Q. "How long can a car sit before the battery dies?"
    The battery in your car can die within as little as two weeks when unused. While our cars are more technologically advanced than ever, this comes at a cost. Due to the various gadgets and computer technology manufacturers include in our vehicles, the newest models coming off the line are always on, continually monitoring the car’s systems around the clock.
  • Q. "Does the temperature affect my vehicle's battery?"
    Hot and cold temperatures can ruin your battery, especially if it’s already weak. Most customers in warm, southern climates don’t realize that hot weather drains their batteries. On the other hand, cold temperatures slow down chemical reactions, which means that your car battery will become sluggish and appear to be far lower than it actually is. Most modern batteries are designed to deliver an abundance of power at what is considered a “cold crank” temperature, but older batteries or batteries which are further into their lifespan may even fail to start your car on a particularly frigid and frosty morning.
  • Q. "Why do car batteries fail?"
    The answer to this popular question includes many different reasons, ranging from age, corrosion, alternator problems, extreme weather conditions, or the classic case of headlights being left on. We explain why these common problems affect your vehicle’s battery on our auto repair blog.
  • Q. "Do you look at all makes and models?"
    Yes! Christian Brothers Automotive has been providing reliable car maintenance and repair for over 40 years. Over that time, our professionals and ASE-certified technicians have handled a vast range of makes and models, and they continue to navigate the forefront of the auto industry’s technologies. If you own a vehicle from a major American or foreign car maker, we are ready to service it.
  • Q. "Do you offer a warranty?"
    As part of our Nice difference.® commitment to providing our customers the best auto service experience possible, we also offer a3-year/36,000-mile warranty on all the work that we do. We offer this warranty at every Christian Brothers Automotive nationwide, and it will be honored at any location, regardless of which branch did the initial work.
  • Q. "How do I jump start my car?"
    You will need a pair of jumper cables and either a portable jump starter or another vehicle's battery. Check out this guide for step-by-step directions to jump-start your car.
