A dead battery always seems to happen at the worst time: before work, in a parking lot, or the morning of a long drive. Roadgun Mobile Repair comes to you anywhere around Jacksonville, NC, tests the battery and charging system, and installs a new battery where the vehicle sits.
Heat in eastern North Carolina is hard on batteries. Summer temperatures break them down from the inside, and many fail the first cold morning in fall. Testing before you replace matters, because a weak alternator or a parasitic drain will kill a brand new battery just as fast.
What is included
- Battery load or conductance test
- Charging system test to confirm the alternator is doing its job
- Starter draw check when the complaint is slow cranking
- Terminal and cable cleaning, and replacement of corroded ends
- Installation of a correctly sized battery for your vehicle
- Parasitic draw testing when a battery keeps dying overnight
How a mobile visit works
Call with your vehicle and where it is parked. If it will not start, tell us, and we will come ready to jump it or test it in place. We confirm the right battery group size for your vehicle before we head out.
On site, we test before we replace. If the battery is the problem, we swap it, clean the connections, and verify charging voltage with the engine running. If the test points to the alternator, starter, or a drain, you will know before you spend money on a battery you did not need.
Driveway or shop: what it costs you
Replacing a battery in the driveway saves a jump start from a friend, a trip to the parts store, and the hassle of doing the swap yourself. Some newer vehicles also need the battery registered or have hard-to-reach battery locations, which is where having a mechanic do it pays off.
Price depends on the battery size and type your vehicle needs. Call and we will quote the battery and install together.
Common signs you need this service
- Slow, labored cranking, especially on cool mornings
- Clicking with no crank
- Dim headlights or interior lights when starting
- Battery warning light on the dash
- Swollen battery case, corrosion on the terminals, or a rotten egg smell
On site or in a shop?
Battery replacement is one of the most common mobile jobs we do. It is almost always done where the vehicle sits, whether that is a driveway, a work lot, or a parking space.
The only time a battery call turns into something bigger is when testing shows the real problem is elsewhere. A failed alternator or starter is usually still a driveway job. A deep electrical short or a wiring harness problem may take more time, and we will tell you what we find.
Frequently asked questions
Can you replace my battery if the car is completely dead?
Yes. That is the most common situation we see. We test and replace in place, then confirm the vehicle starts and charges before we leave.
How long do car batteries last in Jacksonville?
In hot climates like coastal North Carolina, many batteries last around three to five years. Heat shortens battery life more than cold does, even though cold mornings are when they finally quit.
My new battery died again. What is wrong?
Usually the alternator is not charging or something is drawing power with the key off. We test the charging system and check for parasitic draw to find it.
Do you handle AGM and start-stop batteries?
Yes. Many newer vehicles use AGM batteries and some need the new battery registered with the vehicle. Tell us your vehicle and we will plan for it.
