Is It The Battery Or The Charging System? Bedworth van jumpstart
Not sure if it is the battery or the alternator in Bedworth? We test both under load before recommending anything. Mobile van jumpstart across CV12.
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.
Commercial vans park up cold overnight in Bedworth and refuse to start when the temperature drops. That's parasitic drain plus an ageing battery — a jumpstart on the spot beats a tow every time.
Around Bedworth the common jobs are morning no-starts on the yard, lunch-break dead batteries at customer sites, and end-of-day flatlines after tail-lift or refrigeration use.
Who needs this test
Anyone in Bedworth who has been told "it's the battery" twice and is not convinced.
Domestically, ex-mining terraces and 1960s estates dominate around here, which shapes how these jobs are accessed and worked.
How the two faults present
Drivers doing longer runs from Bedworth toward Coventry notice charging faults sooner, because the warning light shows up mid-journey.
Locally that means Bedworth itself plus the neighbourhoods that feed into it, with access via M6 J3 and A444 and a practical radius reaching Nuneaton (~4 mi) and Exhall (~1 mi).
Charging faults found nearby
Recent job nearby: a vehicle in Bedworth 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 Coventry with an intermittent battery light. Ripple test showed a failed diode; the battery itself tested perfectly.
The readings that separate them
- Engine-off resting voltage establishes the battery's state of charge before anything else is judged.
- Belt condition and tension are inspected, since a glazed belt slipping under load mimics a failing alternator.
- 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.

Alternator vs battery questions
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 Bedworth and the CV12 area for this?
Yes. Bedworth is inside our routine coverage from Oldbury via M6 J3, roughly 5 miles from Coventry. We also cover the surrounding neighbourhoods on the same run.
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.My van cranks slowly then dies — is that the battery?
Usually yes, but sometimes it's the starter drawing too much current or a bad earth. We test all three on the driveway before recommending a replacement.
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.

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. For van jumpstart specifically, that means agm and efb stop-start vans handled correctly — no fitting a standard flooded battery in an agm slot
