What is a mobile jump start service?

A mobile jump start is a roadside service where a technician comes to your vehicle and restarts a dead battery on site. McCullers Road Rescue provides 12V and 24V jump starts throughout Chester, Delaware, Philadelphia, and Montgomery counties, 24 hours a day. 12V service starts at $100 and 24V service starts at $150.

12V jump starts from $100; 24V jump starts from $150.

Battery died while driving?

If your battery died while you were driving, or the engine stalls again shortly after a jump start, the issue is likely a failed alternator — not the battery itself. A jump start or battery replacement may not keep the vehicle running. In that case, we recommend calling a tow company and having your vehicle towed to a mechanic for alternator diagnosis and repair.

You're not stranded — a real person answers, confirms the price, and tells you an honest arrival window before anyone is dispatched.

Emergency Battery Diagnostics & Jump Start Walkthrough

This is the exact sequence a MR RESCUE technician follows on a dead-battery call in Downingtown, West Chester, Philadelphia, or anywhere else we dispatch. We diagnose before we jump, because a battery that died while driving is usually an alternator problem.

  1. Step 1 of 5

    Confirm your location and vehicle

    We take your exact location, cross street or garage level, and vehicle year, make, and model on the phone, quote the flat price, and give an honest arrival window before dispatch.

  2. Step 2 of 5

    Secure the scene

    On arrival the technician positions the service vehicle to shield you from traffic, sets hazards, and confirms the vehicle is in park with the parking brake set.

  3. Step 3 of 5

    Test the battery and charging system

    We load-test the battery and read state of charge before applying power, so you learn whether you need a jump, a battery replacement, or a tow to a mechanic for an alternator.

  4. Step 4 of 5

    Connect and start the vehicle

    Clamps go to the correct terminals or manufacturer-designated jump points, we clear corrosion if needed, and start the engine with a professional 12V/24V jump pack instead of cables.

    Verify charging and advise

    With the engine running we confirm the alternator is charging. If output is low, we tell you straight: drive directly to a shop, or arrange a tow — we do not tow, and we will not take money for a jump that will not hold.

Why call MR RESCUE for jump starts

Choosing a roadside company at 2 a.m. on the shoulder of a highway is a trust decision, not a shopping decision. These are the concrete facts about who we are, how we operate, and what you can verify before you ever give us a credit card or a location.

Veteran-owned and operated

MR RESCUE is owned and run by Samuel McCullers, a veteran who answers the phone himself. You are dealing with the owner of the business, not a national call center that brokers your job out to whoever is closest.

Licensed and insured

McCullers Road Rescue LLC is a registered Pennsylvania limited liability company carrying commercial insurance for roadside work. We show up in a marked service vehicle with professional equipment for every call we accept.

24 hours a day, 7 days a week

We answer calls around the clock, including overnight, weekends, and holidays. Dead batteries and flat tires do not keep business hours, so neither do we. A real person picks up and confirms whether we can help before dispatch.

Fast, honest ETAs

Response time depends on your exact location and current job load, so we give you a real arrival estimate on the phone instead of a marketing promise. If we cannot reach you quickly, we say so and you can call someone else.

Locally owned, locally based

We are based in Downingtown, Pennsylvania and work Chester, Delaware, Philadelphia, and Montgomery counties plus parts of Berks and Lancaster. We know these roads, the highways, and the parking garages our customers get stuck in.

Transparent, quoted-up-front pricing

Roadside Assistance Starting at $100. Extended Service Areas Starting at $115. Final pricing depends on distance, location, vehicle type, and requested service. You hear the number before we dispatch, and no membership or annual fee is ever required.

No-surprise guarantee

We quote the price before we dispatch and we do not charge for work we cannot complete. If the job turns out to be outside what we can safely do on scene, we tell you directly and point you toward the right provider instead of billing you for a wasted trip.

Payment collected at time of service

Nothing is prepaid and there is no subscription. Payment is collected once the work is finished. If you need to confirm which payment methods we currently accept for your job, ask on the phone and we will tell you before we roll.

Real customer reviews

We ask every customer for an honest review after the job, and we publish them on our reviews page rather than cherry-picking quotes. Read what other drivers in Chester, Delaware, Philadelphia, and Montgomery counties experienced before you call.
