Our Battery Service Process
Your appointment begins with diagnostics and inspections using manufacturer-equivalent equipment. We then send you a Digital Vehicle Inspection report by text, including pictures and videos that show what our technicians found.
A service advisor reviews the findings with you and answers your questions before any recommended work proceeds. You can also approve the work directly through the Digital Vehicle Inspection. Once approved, we perform the service immediately or schedule it according to parts and customer availability.
1. Schedule Your Appointment
Whether scheduling online or over the phone be sure and let us know what you're experiencing so we can provide fast and accurate service advice.
2. Diagnostics and Inspections
Drop off your vehicle and the shop will get to work with inspections and diagnostics using the same equipment as the manufacturers to determine issues and next steps.
3. Digital Vehicle Inspection Report and Estimate
Following the diagnosis we will text you a digital vehicle inspection report, containing pictures and videos of our findings and recommendations.
4. Review and Approval
A service advisor will reach out to walk you through the findings and recommendations to determine how you would like to proceed, or you can approve work directly in your DVI.
5. Work Performed or Scheduled
Most work can be completed immediately, or scheduled based on parts and customer availability.
Battery Testing Before Replacement
We start with a visual inspection for corrosion, physical damage, bloating, and other signs of deterioration. We then use digital equipment to measure battery voltage and Cold Cranking Amps, which indicate how much starting power the battery can deliver in cold conditions. These results show whether the battery holds a charge or is approaching the end of its usable life.
Professional Battery Installation & Terminal Care
When testing confirms replacement is needed, we clean the terminals and cable ends to remove corrosion before securely installing the new battery. We apply protective terminal spray to help limit future corrosion. After installation, we retest the charging system and complete any necessary electronic resets.
Preventive Battery Care
A battery can lose starting capacity before it fails completely. Routine testing identifies declining performance early, while terminal cleaning addresses corrosion that interferes with the electrical connection. Staying on top of battery maintenance helps you avoid unexpected breakdowns and keeps your car dependable year-round. Proactive attention is especially useful when you notice changes in starting speed, lighting, or electrical accessory performance.
Signs You Need a Battery Replacement
Your vehicle usually gives warning signs before a complete failure. The most common indicator is a slow engine crank, where the engine sounds sluggish when starting. You might also notice dim headlights that flicker at idle but brighten as you drive. These issues suggest the battery is struggling to deliver the necessary voltage for reliable performance.
Watch for these common symptoms:
- Battery warning light is illuminated on the dashboard.
- Electrical accessories, like power windows, move more slowly than usual.
- Visible corrosion or white powder appears around the terminals.
- Rotten egg smell comes from the engine bay.
If you spot these issues, we recommend getting your battery checked right away to avoid getting stranded.
Physical signs can include a swollen battery case or visible leaks. If you notice either condition, the battery requires prompt inspection and replacement. A check engine light can have many causes, so it requires diagnostic testing rather than being attributed specifically to the battery.
Frequently Asked Questions
Here are answers about replacement timing, warning signs, used-battery recycling, and warranty coverage.
How Often Should I Replace My Car Battery?
Most car batteries need to be replaced every three to five years, but driving habits, temperature, maintenance, and battery condition affect service life. If your battery has trouble holding a charge, our technicians can test it and help you decide when replacement is appropriate.
When we perform regular battery checks, we also examine other vehicle parts like the alternator or starter that could cause battery issues. This all-in-one approach helps you care for your entire car and identify the source of starting or charging concerns.
What Are the Signs My Battery Needs Replacing?
Dim headlights, slow engine cranking, and frequent jump-starts all warrant prompt testing.
A battery warning light also warrants testing. Our team runs diagnostic tests to distinguish a weak battery from an alternator, starter, or other electrical-system concern.
Does CBAC recycle old car batteries?
Yes, we recycle all used car batteries to limit environmental impact. You don’t need to worry about disposal because we take care of it, making your car battery replacement service easy and eco-friendly.
Proper battery recycling matters because car batteries contain hazardous materials. Responsible handling keeps those materials out of ordinary waste streams.
Does Your Battery Installation Come with a Warranty?
Most premium batteries we install include a manufacturer’s free-replacement warranty. Coverage typically lasts two to three years, depending on the battery grade.
Our Nice difference.® warranty covers qualifying repairs for 3 years or 36,000 miles, whichever occurs last. Qualifying repairs are honored nationwide at Christian Brothers Automotive Commerce City locations.
Schedule Battery Testing or Replacement
Battery replacement cost depends on your vehicle’s battery requirements and whether testing identifies a related electrical issue. Schedule an inspection to receive findings and a vehicle-specific quote before approving service.

Is It My Battery or My Alternator That Is the Problem?
This is a common question because the symptoms can be similar. If your car starts but stalls shortly after, or if your headlights flicker while you’re driving, the alternator output requires diagnosis. If the car simply clicks when you turn the key and won’t start at all, a discharged or failing battery is one possible cause. The battery stores electrical energy for starting, while the alternator supplies power and recharges the battery while the engine runs.
To know for sure, professional diagnostics are required. Our technicians perform a test that checks the battery, starter, and alternator. This ensures we don’t replace a good battery when the alternator is actually the culprit. The test identifies which part of the system requires attention before replacement work is approved.
Do I Lose My Radio Presets & Settings During Installation?
In older vehicles, disconnecting the battery often resulted in lost radio presets and clock settings. In modern vehicles, power loss can also reset the engine control module, affecting some vehicle settings until the computer relearns operating data. At Christian Brothers Automotive Commerce City, we use a memory saver device whenever possible during the installation process.
This device plugs into the onboard diagnostic port, also called the OBD-II port, and supplies a small amount of power while the main battery is disconnected. Whenever possible, it preserves radio presets, seat positions, and computer data. Battery installation also includes an electronic reset and charging-system retest.

FAQs
-
Q. "How long can a car sit before the battery dies?"The battery in your car can die within as little as two weeks when unused. While our cars are more technologically advanced than ever, this comes at a cost. Due to the various gadgets and computer technology manufacturers include in our vehicles, the newest models coming off the line are always on, continually monitoring the car’s systems around the clock.
-
Q. "Does the temperature affect my vehicle's battery?"Hot and cold temperatures can ruin your battery, especially if it’s already weak. Most customers in warm, southern climates don’t realize that hot weather drains their batteries. On the other hand, cold temperatures slow down chemical reactions, which means that your car battery will become sluggish and appear to be far lower than it actually is. Most modern batteries are designed to deliver an abundance of power at what is considered a “cold crank” temperature, but older batteries or batteries which are further into their lifespan may even fail to start your car on a particularly frigid and frosty morning.
-
Q. "Why do car batteries fail?"The answer to this popular question includes many different reasons, ranging from age, corrosion, alternator problems, extreme weather conditions, or the classic case of headlights being left on.
