Is It The Battery Or The Charging System? Tile Hill fleet jumpstart
Not sure if it is the battery or the alternator in Tile Hill? We test both under load before recommending anything. Mobile fleet jumpstart across CV4.
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.
Fleets working out of the CV4 area — courier, plumbing, electrical, HVAC, roofing, letting agents — call us daily. We know your vans, we know your yard, we know when your first drop is.
Fleet vans die from parasitic drain more than anything — trackers, dashcams, tail-lifts, refrigeration. We identify the drain, not just recharge the battery.
How the two faults present
Drivers doing longer runs from Tile Hill toward Coventry notice charging faults sooner, because the warning light shows up mid-journey.
Locally that means the streets between Tile Hill and Coventry, with access via M6 J2/J3 and M69 and a practical radius reaching Coventry (~4 mi) and Nuneaton (~9 mi).

Jumped and died again?
That is a charging symptom. We test the alternator under real electrical load before anyone mentions a new battery. We route in via M6 J2/J3, roughly 4 miles out from Coventry.
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.
- Vehicle register held on file — one call gives us the reg, spec, battery history and yard location
- Fleet & Business Jumpstart work here is judged against the vehicle's own specification rather than a generic pass mark.
Alternator vs battery questions
Q.Do you cover Tile Hill and the CV4 area for this?
Yes. Tile Hill is inside our routine coverage from Oldbury via M6 J2/J3, roughly 4 miles from Coventry. We cover it alongside Coventry and the surrounding streets.
Q.Can drivers call directly?
Yes — we tag your account against your fleet's registered numbers so drivers don't need to authorise every call, and admin still sees one invoice.
Q.What if a driver is stranded outside our depot?
That's what account customers get priority for — one call from the driver, we handle it and bill your account, no card payment at the roadside.
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.
Charging faults found nearby
Recent job nearby: a vehicle in Tile Hill 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.
Areas we test in
As a neighbourhood of Coventry, Tile Hill is covered alongside its parent town, so a alternator or battery? call from any of them routes to the same engineer.
Why this is safe to book
- Where the fault is beyond our scope we say so plainly instead of selling a battery anyway.
- Fixed prices agreed before dispatch — no callout fee just to open the bonnet in CV4.
How the visit runs
- 1
Onboard the fleet
One call, one fleet list, account live the same day for first callouts.
- 2
The readings that separate them
Engine-running voltage should sit roughly between 13.8V and 14.7V — below 13.2V under load is a charging fault regardless of how new the battery is.
