Mobile van jumpstart · Alternator or battery?
Is It The Battery Or The Charging System? Langley van jumpstart
Battery light on, or a car that dies after a jump in Langley? That points to charging, not storage. On-site diagnosis and Van Jumpstart.
A simple rule of thumb: a battery fault stops you starting, a charging fault stops you continuing. If the car jumps easily then dies a few miles later, the alternator is the prime suspect.
If your work van is stone dead around Langley, don't book recovery yet. Most van no-starts near the M5 J2 corridor are cured with a mobile jump and a proper alternator/battery health check on the driveway.
Residential district south of Oldbury on the A4123. — that means a mix of tight residential streets and industrial estates, and we're set up to work in both without needing a low-loader.

How the two faults present
Drivers doing longer runs from Langley toward Oldbury notice charging faults sooner, because the warning light shows up mid-journey.
Locally that means the streets between Langley and Oldbury, with access via M5 J2 and A4123 and a practical radius reaching Oldbury (~1 mi) and Langley (~1 mi).
The readings that separate them
- Belt condition and tension are inspected, since a glazed belt slipping under load mimics a failing alternator.
- Ripple voltage is checked for failed diodes in the rectifier pack, which can charge adequately but destroy a battery over months.
- Heavy-duty 2000A+ lithium jump pack rated for diesel commercials up to 7.5t
- On a van jumpstart the equipment is matched to the vehicle — cranking current, terminal layout and battery location all change the approach.
Who needs this test
Anyone in Langley who has been told "it's the battery" twice and is not convinced.
Domestically, Victorian terraces and modern estates dominate around here, which shapes how these jobs are accessed and worked.

Charging faults found nearby
Recent job nearby: a vehicle in Langley jumped four times in a week. Charging voltage 12.7V at 2,000rpm with lights on — alternator, not battery, and the owner stopped throwing money at parts.
Recent job nearby: a car near Oldbury with an intermittent battery light. Ripple test showed a failed diode; the battery itself tested perfectly.

Alternator vs battery questions
Q.The car started on jump leads and then died. What does that mean?
Classic charging fault. The engine ran on borrowed energy and stopped when the battery could no longer supply the ignition system.
Q.Can a bad alternator ruin a new battery?
Yes, in both directions. Undercharging sulphates the plates; overcharging boils off electrolyte. Both shorten life dramatically.
Q.Do you replace alternators too?
We diagnose them on-site and can replace batteries on the spot. Alternator replacement is a workshop job, and we will tell you exactly what needs doing so you are not paying for diagnosis twice.
Q.Do you cover Langley and the B68 area for this?
Yes. Langley is inside our routine coverage from Oldbury via M5 J2, roughly 1 miles from Oldbury. We cover it alongside Oldbury and the surrounding streets.
Q.Do I need to register a new van battery to the ECU?
On Sprinters, Crafters, T6 Transporters and newer Custom Transits — yes. We carry the OBD tool and code it as part of the fit.
Q.What if the van battery keeps going flat every week?
That's parasitic drain — usually a dashcam, tracker or aftermarket electrics wired to permanent live. We do a milliamp draw test and identify the circuit.

Jumped and died again?
That is a charging symptom. We test the alternator under real electrical load before anyone mentions a new battery. Same fixed pricing whether it is a van jumpstart at 9am or 3am, anywhere in Sandwell Metropolitan Borough Council.
The short version
Storage fault or supply fault — the tests are different, the costs are different, and guessing is expensive. Every visit here includes the charging check. That is the whole job: diagnose it properly, fix it once, and explain what caused it.
