About Us
Most people find us on a bad day.
The car won’t start. The battery’s dead. Schedule blown.
That’s where AABCO Automotive comes in.
We’re a family-owned shop in Chattanooga that’s been fixing starters, alternators, and batteries since 1969. Same location. Same focus. Same belief that honest work beats fancy talk every time. No call centers. No upsells disguised as “recommendations.” Just real diagnostics, clear answers, and repairs that get you back on the road without the headache.
Before You Replace It, Test It
We’ll check it, explain it, and fix it usually the same day. Wi-Fi’s on while you wait.
Providing All Types of Car Maintenance Services
Starter Repair, Replacement & Rebuilds
When your car won’t start, guessing wastes time. We test starters properly because a bad starter can look like a battery problem, and wiring issues can be deceptive. New, rebuilt, or personal rebuilds, all backed by a 1-year warranty. Turn the key with confidence again.
01
Alternator Repair, Replacement & Rebuilds
Dim lights. Dead batteries. Dash warnings that won’t quit. A failing alternator causes chaos fast. We diagnose the real issue, explain your options, and fix only what’s needed. Rebuilt alternators come with a 1-year warranty, no scare tactics, just facts.
02
Battery Sales, Testing & Replacement
Batteries don’t give notice, and Tennessee heat makes it worse. We test for real performance, not just voltage, so you’re not replacing a battery that still has life left. New and refurbished options available for cars, trucks, motorcycles, tractors, and ag equipment.
03
Refurbished Batteries
Reliable. Tested. Budget-friendly.
Refurbished batteries are a smart option for secondary vehicles, farm equipment, or seasonal use. Each one is professionally tested and backed by a 6-month warranty, so “used” doesn’t mean risky.
04
Electrical Services for All Vehicle Types
Cars are just the beginning. We service trucks, tractors, motorcycles, agricultural equipment, and anything with a battery. With the largest inventory in the Tri-State area, most repairs are done the same day. Sometimes in just a couple of hours.

Testimonials
“My truck wouldn’t start at work, and I was sure it was the battery. Turns out it wasn’t. They tested everything, explained it clearly, and had me back on the road before lunch.”
“I’ve been coming here for years. They don’t sell you parts you don’t need, and that’s rare these days.”
“Fast, honest, and affordable. I brought in my tractor battery, and they treated it with the same care as a car repair.”
“Another shop told me I needed a new alternator. AABCO tested it and instead fixed a wiring issue. Saved me a lot of money.”
“You can tell these guys know electrical systems. No guessing, no drama, just solid work.”
“I waited on-site and used the Wi-Fi while they worked. They were done quicker than I expected and explained everything before I paid.”
“My starter was rebuilt instead of replaced. Works perfectly, and the warranty gave me peace of mind.”
“Family-owned feel. Straight answers. That’s why I keep coming back.”
