Professional On-Site Battery Replacement
Battery Replacement from MR RESCUE (McCullers Road Rescue LLC) is mobile, on-site service performed where your vehicle sits — no towing, light-duty passenger vehicles only. Flat-rate pricing starts at $100 in standard areas, $115 in extended Pennsylvania areas, quoted on the phone before dispatch. We dispatch 24 hours a day, 7 days a week from Downingtown, PA across Chester, Delaware, Montgomery, Bucks, and Philadelphia counties — call (267) 249-5891.
Mobile battery replacement is on-site installation of a new 12V starting battery so you do not have to be towed to a shop. McCullers Road Rescue offers this service by appointment only — it is not a 24/7 emergency dispatch. We install a replacement battery you already own starting at $100, test the connection, and clean the terminals. Call to schedule a time that works for you.
Mobile battery replacement assistance, by appointment only, for a battery that won't hold a charge.
If your battery won't hold a charge, we can install a replacement battery you already have, starting at $100. Battery replacement is scheduled by appointment — if you are stranded right now, call us for a jump start instead.
If you need us to source the battery for you, call to confirm current pricing and availability before dispatch. When we supply the battery, your total includes the battery cost, sales tax, and the core charge. MR RESCUE keeps the old battery core.
Battery replacement is scheduled in advance rather than dispatched as an emergency call, so we can confirm the correct battery and reserve a time window for your vehicle. Call or text us to book an appointment. If you are stranded right now, ask for a jump start — that service is available 24/7.
Roadside Assistance Starting at $100
Extended Service Areas Starting at $115 · Final pricing depends on distance, location, vehicle type, and requested service.
No membership, no annual fee, and no hidden charges — you hear the number before we dispatch.
See full pricingIf 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.
If your vehicle dies again a few hours after a jump, the battery is finished and another jump is a waste of your time. We replace it where you are — removal, terminal cleaning, secure installation, and a verified connection — so you skip the shop visit entirely.
The table below summarizes what this service costs, how long it usually takes, when it is available, and what it does not include. If anything here does not match your situation, call us first and we will tell you honestly whether this is the right service before anyone is dispatched to your location.

Battery replacement is by appointment only and is not dispatched as an emergency roadside call. We do not service semi-trucks, tractor-trailers, buses, RVs, motorhomes, or motorcycles.
Passenger cars, SUVs, crossovers, minivans, pickup trucks, and most light-duty vehicles only.
Battery replacement is scheduled by appointment so we can confirm the correct group size and reserve a window. Here is what happens at your driveway, office lot, or parking garage.
Step 1 of 5
On booking we take year, make, model, and trim to confirm the correct group size, terminal layout, and whether the vehicle needs an AGM or EFB battery.
Step 2 of 5
We test the existing battery, starter draw, and alternator output on site. If the battery is healthy and the alternator is failing, replacing the battery is the wrong fix and we say so.

Step 3 of 5
A memory saver keeps the ECU, radio presets, and window calibration alive while the old battery comes out, on vehicles that support it.
Step 4 of 5
Terminals and trays are cleaned, the new battery is seated and hold-down hardware torqued so nothing shifts, then terminals are protected against corrosion.
Step 5 of 5
We confirm charging voltage under load, reset or register the battery where the vehicle's charging strategy requires it, and hand you the old core — we retain it when we supplied the battery.

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.
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.

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.
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.
