What Causes a Car Battery to Drain Too Quickly?
Let’s break down the top five culprits.
- Leaving Lights or Electronics On: It sounds simple, but interior lights, headlights, or even a phone charger left plugged in overnight can zap your battery. These small drains add up and leave you with no power when you need it most.
- A Weak or Aging Battery: Car batteries don’t last forever. Over time, they lose the ability to hold a full charge. If your car’s battery is more than three to five years old, it might be time to swap it out before it strands you.
- Faulty Alternator: Your alternator is responsible for keeping the battery charged while you drive. If it’s not doing its job, the battery won’t recharge, and you’ll be left scratching your head every morning.
- Parasitic Drain: Even when your car is off, specific systems (like alarm systems or radios) draw a little power. If something malfunctions, that small draw turns into a big drain, quietly killing your battery overnight.
- Extreme Weather: Both scorching heat and chilly cold can weaken a battery’s ability to hold a charge. In Puerto Rico’s hot climate, heat is often the silent culprit.
