Battery & Electrical

Starts every morning, every time.

Modern vehicle electrical systems are intricate, and batteries do a lot more than just start the car these days. A weak battery or bad cell can cause all kinds of electronic gremlins.

In today's cars, the computer and sensors talk to the alternator constantly, telling it how much power to provide and when. We have the equipment to test, isolate, and repair the issue — big or small.

Common questions

Why do car batteries die so fast in Las Vegas?

Heat, not cold, is what kills batteries. High temperatures speed up the chemical breakdown inside, so a battery that would last five years in a mild climate often lasts two or three here. If yours is past two years old, have it tested before summer does the testing for you.

How do I know if it's the battery or the alternator?

A weak battery usually shows up as slow cranking, especially first thing in the morning. A failing alternator more often shows as dimming lights or a battery warning light while driving. We'll test both and tell you which one it actually is — they're cheap to test and expensive to guess at.

My car's electrical gremlins come and go — can you find those?

Intermittent problems are frustrating, but they're findable. Heat expands connections and worsens corroded grounds, which is why gremlins love summer. We'll trace it methodically instead of throwing parts at it.
