BATTERY QUESTIONS WE ANSWER EVERY WEEK

Straight answers from our techs

WHY DOES MY BATTERY KEEP DYING?

Either the battery is worn out, the alternator is not charging it, or something is drawing power with the vehicle off. Replacing the battery alone only fixes the first one.

Warning signs

Dead after sitting  Â·  Slow crank  Â·  Battery light  Â·  New battery died too

What we do

We test the battery, the charging output and the key-off draw, so you fix the real cause the first time.

Colorado Springs:  Cold mornings are when weak batteries fail. Get it tested before the first hard freeze.

HOW DO I KNOW IF IT IS THE BATTERY OR THE ALTERNATOR?

A bad battery usually struggles to start the vehicle. A bad alternator lets it start but drains the battery while you drive, often with a warning light or dim lights.

Warning signs

Battery warning light  Â·  Dim or flickering lights  Â·  Whine from the engine bay  Â·  Dies while driving

What we do

We test both on the vehicle and show you the readings before recommending a part.

Colorado Springs:  Short winter trips may not recharge a weak battery. A test tells you where it stands.

WHY DOES MY CAR CLICK BUT NOT START?

A single click or rapid clicking can mean a weak battery, a bad connection, a failing starter or a relay. Each one needs a different fix.

Warning signs

Rapid clicking  Â·  Single click  Â·  Lights work but no crank  Â·  Intermittent no-start

What we do

We test voltage at each point in the starting circuit to find the failed part.

DO DIESEL TRUCKS NEED BOTH BATTERIES REPLACED?

Most diesel pickups run two batteries that work as a pair. A weak one drags the good one down, so they are usually tested and replaced together.

Warning signs

Slow cold crank  ·  Uneven battery test  ·  Corroded cables  ·  Glow plug season

What we do

We load-test each battery separately and check both cable sets before recommending anything.

WHAT DRAINS A BATTERY OVERNIGHT?

Modules that do not go to sleep, aftermarket accessories, stuck relays and lights that stay on are the usual causes.

Warning signs

Dead after a few days  Â·  Dead every morning  Â·  Accessory installed recently  Â·  Warm battery

What we do

We measure the draw with the key off and trace it circuit by circuit until we find the source.

Colorado Springs:  A vehicle that sits for weeks, like during a deployment or a long trip, can come back to a dead battery. A tender helps.

NOT SURE WHY IT WON’T START?

Tell us what it does when you turn the key. We test before we replace anything.
