FAQ: 8 Signs of a Failing or Flat Car Battery
What are the main signs my car battery is failing?
Slow engine cranking, clicking sounds when you turn the key, or complete failure to start.
Why are my lights and electronics acting up?
Dimming headlights, weak interior lights, slow power windows, or random dash errors can all point to a weak battery.
Why does my remote key or central locking stop working properly?
A weak battery reduces voltage to the car’s electronics, which can cause shorter key fob range or doors not unlocking smoothly.
Can cold weather make battery problems worse?
Yes. Cold reduces a battery’s efficiency, so weak batteries often fail in winter.
Do frequent jumpstarts mean I need a new battery?
Yes. A healthy battery should not need boosting more than once in unusual circumstances.
What voltage reading shows my battery is weak?
12.6V is fully charged. Below 12.4V means partly discharged, and under 12.0V usually means failing.
How do I tell if it’s the battery or the alternator?
If the car runs at less than 13.7–14.7 volts while the engine is on, the alternator may be faulty. If it charges fine but won’t hold charge, it’s the battery.
What is a Battery load test?
A load test simulates starting conditions to see if the battery can deliver enough current. It quickly reveals weak batteries that still show good voltage. Our technicians can do this for a small additional fee on the spot.
