Battery Replacement service

Quick answer

Highway 35 Roadside provides 24-hour mobile car battery delivery and installation across DFW at homes, apartments, offices, garages and safe roadside locations. We confirm the year, make, model, group size and terminal layout before dispatch, then test the battery and charging system on site. Arrival time depends on your location, traffic and weather. The battery and installation total is quoted before dispatch. Call (469) 340-3500 to dispatch a tech now.

Do we service your vehicle?

Straight answers on what we can and cannot handle at the roadside — no guessing before you call.

Do you service electric vehicles?Yes
Yes. We handle EV tire changes, EV lockouts including frunk and phone-as-key failures, and the 12-volt auxiliary battery that strands most EVs. We do not charge a depleted traction battery on the roadside.
Do you service hybrids?Yes
Yes. Hybrid 12-volt batteries, jump starts, tires, lockouts and fuel are all standard work for us. We follow the manufacturer jump points rather than clamping the traction system.
Do you service motorcycles?Yes, with limits
Yes, with limits. Tires, batteries, jump starts and locked ignition or fuel-tank locks only. We do not tow motorcycles — for that you need a motorcycle-rated flatbed.
Do you service RVs and campers?Yes, with limits
Yes, with limits. Tires, house and chassis batteries, diesel-rated jump starts and lockouts on Class A, B and C motorhomes, fifth-wheels and travel trailers. We do not tow RVs.
Do you service commercial vans and box trucks?Yes
Yes. Fleet vans, box trucks and tractors get priority dispatch, heavy-duty jump starts from a 4250-amp pack, tire work, batteries and fuel. Fleets can be invoiced directly instead of paying at the roadside.
Do you tow?No
No. We are a non-tow roadside company. If your vehicle needs to be moved rather than fixed where it sits, you need a flatbed service — we will tell you that plainly instead of dispatching a truck.
Do you do mechanical repairs?No
No. We fix what strands a driver at the roadside — tires, batteries, jump starts, lockouts and fuel. Alternators, starters, transmissions and collision damage belong in a shop.

What battery replacement actually means

Battery replacement is mobile install: we bring the right battery to your location, swap it out, recycle the old core, and verify the charging system. No tow to a parts store, no waiting in line at a shop service desk.

Most modern batteries last 3–5 years in DFW heat. When yours is on the way out, you usually find out in a parking lot at the worst possible time. That's the call we want.

We carry the most common Group sizes on every truck and can source rarer sizes within about 30 minutes from local distributors. Pricing is the unit cost plus a small mobile install fee — far less than a dealer install with a tow.

Mobile car battery replacement is the whole job done where the car sits: driveway, apartment lot, office deck, garage level, or the shoulder. Nothing gets loaded, nothing gets left overnight at a shop. Most DFW drivers who search for a car battery replacement near me are within a 20–40 minute dispatch window at any hour, including 2 a.m., weekends, and holidays, at the same flat rate.

The symptom pattern usually tells us before we arrive. A slow, laboring crank that gets worse on cold mornings, dash lights that dim while the starter turns, a click-click-click with no crank, or a car that starts fine off a jump and is dead again the next morning — those are end-of-life battery signs, not alternator signs. A car that dies while driving, or that keeps killing new batteries, is a charging-system problem, and the on-scene charging test tells us which one you have before you pay for the wrong part.

Battery install kit on every truck

Every truck rolls fully stocked. Most calls finish on the first visit, not after a callback for the right tool.

Common battery sizes stocked on-truck

Group 24F, 35, 48, 65 — covers the majority of DFW vehicles.

Battery analyzer (CCA, voltage, reserve)

Confirms the old battery is genuinely the failure point.

Memory-saver tool

Keeps radio presets, clock, and adaptive transmission learning intact during the swap.

Terminal cleaning brush and protectant

Clean posts and clamps prevent recurrence.

Torque-rated terminal wrench

Loose terminals create new no-start problems — we torque to spec.

Recycling crate for old cores

We haul the old battery away for recycling after installation.

On-scene workflow

The exact steps a tech runs after they arrive at your pin.

  1. 1

    Confirm the battery is the failure

    CCA test on the old unit; charging-system test on the alternator.

  2. 2

    Match the new battery to spec

    Same group size, same or higher CCA, same terminal layout.

  3. 3

    Connect memory saver

    Keeps electronics live during the swap.

  4. 4

    Remove old battery

    Disconnect negative first, then positive; lift safely (modern batteries can be 50+ lbs).

  5. 5

    Clean terminals and tray

    Wire brush, protectant spray, visual check for corrosion.

  6. 6

    Install and torque the new battery

    Positive first, negative second; clamps torqued to spec.

  7. 7

    Verify and recycle

    Test the new install under load, confirm charging, haul the core away.
