At Deltec Batteries, we’re here to keep you powered through the cold, starting with these common culprits of battery damage and how to avoid them.

1. The Cold… Yes, Even in Cape Town

Winter mornings drop below 5°C in many parts of South Africa, and that’s enough to reduce your battery’s efficiency. Cold slows the chemical reactions inside your battery, making it harder to start your car, especially if the battery is already weak.

Deltec Tip: Park in a garage or covered spot if you can. Ask about our free winter battery check at Deltec Bellville or Tokai.

2. Too Many Short Trips

Driving five minutes to the shop and back doesn’t give your alternator enough time to recharge the battery. Do that a few times a week, and your battery will slowly weaken.

Deltec Tip: If you’re doing mostly short trips, take a longer drive once or twice a week—or better yet, plug in a smart charger overnight.

3. Oops, You Left the Lights On

Even modern cars can drain batteries fast if interior lights, radios, or accessories are left on overnight. And in winter, your battery already has to work harder.

Deltec Tip: Double-check lights and infotainment screens when switching off. Or ask us about installing an automatic shutoff system.

4. Dirty or Loose Battery Terminals

A thin layer of corrosion on your battery terminals can be enough to cause starting problems—especially in winter when your battery is under pressure.

Deltec Tip: Come in for a quick clean-and-tighten service. We’ll get those terminals sparkling and connected like they should be.

5. A Faulty Charging System

If your alternator isn’t working properly, your battery might not be charging fully. That’s a big issue when cold mornings demand full power to get your car started.

Deltec Tip: Visit us for a charging system diagnostic. It’s a fast and simple check—and could save you from an unexpected breakdown.

6. Your Battery Is Just Too Old

No battery lasts forever. Most lead-acid and AGM batteries last between 2 and 3 years—less if they’ve been abused by short trips or heat.

Deltec Tip: Check the date stamp on your battery. If it’s more than 2 years old, get it tested. If you need a new one, the Deltec 628B is going for only R1 190 this winter!

7. Off-Road Vibes? Check Your Battery Mounting

Vibrations from rugged roads can cause internal battery damage or shake your terminals loose. That’s bad news if you’re an overlander or off-road enthusiast.

Deltec Tip: We offer professional battery fitment and Front Runner gear installs that ensure your battery stays secure—no matter how rocky the ride.

8. Letting Your Car Sit for Too Long

Going away for the weekend or working from home more than usual? A parked car doesn’t mean the battery isn’t working—it’s still slowly discharging.

Deltec Tip: Use a maintenance charger or stop by for a free battery health check. We’ll help you avoid the dreaded click-click-click of a dead battery.

9. Using the Wrong Battery Type

Your car’s electronics are sensitive. Using the wrong battery—wrong size, specs, or chemistry—can lead to issues, especially during seasonal changes.

Deltec Tip: We stock high-quality lead-acid and AGM batteries—and nothing else. Our trained team will fit the right one, every time.
