Alternator Or Battery? On-Site Testing in Bedworth
Not sure if it is the battery or the alternator in Bedworth? We test both under load before recommending anything. Mobile emergency jumpstart across CV12.
The two faults feel identical from the driver's seat and cost very different amounts to fix. The distinguishing test takes about ninety seconds with the engine running, which is why nobody should be guessing.
Stuck at the roadside in Bedworth at 2am with a dead battery? We run a genuine 24/7 mobile jumpstart service — same price, day or night, no unsociable-hours surcharge.
Emergency calls are logged, timestamped and priced up-front. What you pay at 4am is what you'd pay at 4pm — no exploitation.
Who needs this test
Drivers with a battery warning light that comes and goes.
Domestically, ex-mining terraces and 1960s estates dominate around here, which shapes how these jobs are accessed and worked.
How the two faults present
Around Bedworth this comes up most with higher-mileage vehicles and with cars that have been repeatedly jumped by well-meaning neighbours.
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-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.
- Engine-off resting voltage establishes the battery's state of charge before anything else is judged.
- Genuine 24/7 — nights, weekends, Christmas Day, New Year — same price as daytime
- On a emergency jumpstart the equipment is matched to the vehicle — cranking current, terminal layout and battery location all change the approach.

Alternator vs battery questions
Q.I'm on my own and don't feel safe — can you stay on the phone?
Yes — we do this all the time. We'll stay on the line until we arrive, and you can share your live location if that helps.
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 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.What if my car is in a locked car park overnight?
Tell us on the call — usually a security guard or manager can let us in. We've done this in NCPs, hospital car parks and industrial estates dozens of times.
Why this is safe to book
- Where the fault is beyond our scope we say so plainly instead of selling a battery anyway.
- Old batteries removed and recycled on every emergency jumpstart.
