Drained Car Battery? Learn How to Prevent Dead Batteries and Extend Lifespan

Published on Apr 14, 2023 by Talia Mushinsky

Feeling drained is something we all experience, whether it's due to a long day at work or excessive social interaction. Your car battery may not be attending any parties, but it can still experience similar exhaustion. To avoid a dead battery, it's essential to understand the common causes and how to prevent them.


Let's explore seven reasons why your car battery might be dying frequently and what you can do about it.


Headlights Left On
One of the main reasons for a depleted car battery is leaving your headlights on. While modern vehicles often have automatic shutoff features, older models may not. Make sure to turn off your headlights when leaving your car to avoid draining the battery.


Loose or Corroded Battery Connections
Over time, battery terminals can become loose or corroded, leading to poor electrical connections and preventing the battery from charging properly. Regularly cleaning your car's battery terminals can help prevent this issue. If you're uncertain how to do this, visit your nearest Kunes Service Center, and our expert technicians will gladly assist you.


Parasitic Draw
A parasitic draw occurs when electrical devices or systems continue to use power from the battery even when the vehicle is off. Things like interior lights, door lights, or faulty relays can contribute to this issue. Prevent parasitic draws by ensuring all lights are off and that your trunk, glove box, and doors are securely closed and latched before leaving your car.


Extreme Temperatures
Both sweltering summer heat and freezing winter weather can create issues for your car's battery. Newer batteries are typically more resistant to extreme temperatures, but older batteries may struggle. If you notice your battery having difficulty in harsh conditions, schedule a battery check at your local Kunes Service Center.


Frequent Short Drives
Frequent short drives can take a toll on your car battery, as the alternator may not have enough time to recharge the battery between stops. Over time, this can reduce your car battery's lifespan. Try to combine errands or plan longer trips to give your battery a chance to recharge properly.


Battery Not Charging While Driving
Your car relies on the battery to start the engine and the alternator to keep the battery charged while driving. If your alternator isn't functioning properly, it can't effectively charge your battery, making it difficult to start your car even after driving. In this case, bring your car to the nearest Kunes Service Center for a diagnostics check to determine the issue.


Aging Battery
All batteries have a limited lifespan, which can be shortened by factors like extreme temperatures and frequent short trips. If your car battery dies quickly, even after a jumpstart, it might be time for a replacement.


To keep your battery in good shape, get a battery test at Kunes Service Center near you. We'll inform you of your battery's health and its remaining lifespan. If it's time for a new battery, we'll install a dependable replacement battery for you.
