Car Battery FAQS:

How long do car batteries typically last?

Most car batteries last three to five years on average. However, their lifespan can be influenced by climate (extreme heat or cold), driving habits, and vehicle type. As you probably already know, St. Louis has hot summers, and we get cold winter temperatures.  If you frequently make short trips or leave your car idle for long periods, your battery may wear out more quickly than a car that drives primarily highway miles.

How can I tell if my car battery is bad?

Common signs of a failing battery include:

  • Slow engine cranking (when starting the car)
  • Dim headlights or electrical issues
  • Frequent jump-starts
  • A swollen or corroded battery case, including visible signs or a white residue on the terminal ends.

If you experience any of these issues, it’s best to have your battery tested by a professional. We can tell you whether your battery is failing or if your starting issues are caused by something other than your battery, such as a bad alternator, an electrical problem, worn connections, or the starter.

 Can I still drive with a dying battery?

While driving with a weak battery is possible, it’s not recommended. A failing battery can cause your vehicle to lose electrical power while driving, leading to potential breakdowns. If your battery consistently shows weakness, replace it as soon as possible. Who wants to get stranded on the side of Highway 40 on a Friday night?

Should I disconnect my car battery when not used for a long time?

Yes, disconnecting your battery is a good idea if you’re not using your car for an extended period. Disconnecting the negative terminal prevents battery drain and potential damage. If you don’t want to disconnect it, consider using a battery tender or trickle charger.

Can I jump-start my car with a dead battery?

You can use jumper cables and another vehicle with a working battery to jump-start your car. Make sure to follow the proper steps to ensure your safety:

  • Connect the positive terminals first.
  • Then, connect the negative terminal to a metal part of the car (not the battery).
  • Start the donor car, then try starting your vehicle.

How do I dispose of a car battery?

Car batteries contain hazardous materials and should be disposed of at a recycling center or auto parts store that accepts used batteries. Many retailers offer a discount on a new battery when you return your old one. Never dispose of it in regular trash. Bring your batter to Cyclone for proper disposal.

Can a car battery die suddenly?

Yes, car batteries can die suddenly, especially if they are nearing the end of their lifespan or if the charging system fails. Extreme weather conditions, such as severe cold, can also cause a battery to fail unexpectedly. As temperatures fall, the strain on your battery increases, and the ability for your battery to engage becomes more challenging, which may cause your battery to go dead.

 How do I maintain my car battery?

To maintain your battery:

  • Keep the terminals clean and free of corrosion.
  • Ensure the battery is securely mounted to avoid vibrations.
  • Regularly check the fluid level (for non-sealed batteries) and clean the battery case.
  • Avoid leaving electronics running while the engine is off.

Cyclone Car Care can tell you if your battery needs replacement, can last a few more years, or if your cables or other issues are the problem, not your car battery. Sometimes, a problem that appears to be a bad or failing car battery is the car’s starter, alternator, or ignition cables. We carry a complete line of batteries for all makes and models, and some have more extended warranties.
