Is It The Battery Or The Charging System? Kings Heath fleet jumpstart
Battery light on, or a car that dies after a jump in Kings Heath? That points to charging, not storage. On-site diagnosis and Fleet & Business 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.

Who needs this test
Drivers with a battery warning light that comes and goes.
Domestically, Victorian terraces and small retail parade flats dominate around here, which shapes how these jobs are accessed and worked.
How the two faults present
Around Kings Heath this comes up most with higher-mileage vehicles and with cars that have been repeatedly jumped by well-meaning neighbours.
Locally that means the streets between Kings Heath and Birmingham, with access via M6 J6 (Spaghetti Junction) and A38(M) Aston Expressway and a practical radius reaching Birmingham (~4 mi) and Smethwick (~3 mi).
Charging faults found nearby
Recent job nearby: a vehicle in Kings Heath 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 Birmingham with an intermittent battery light. Ripple test showed a failed diode; the battery itself tested perfectly.
The readings that separate them
- Ripple voltage is checked for failed diodes in the rectifier pack, which can charge adequately but destroy a battery over months.
- 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.
- Bulk battery pricing — replacement AGM/EFB batteries at trade rates, not retail
- Every fleet jumpstart finishes with a charging-system reading, so the same fault does not reappear next week.

Alternator vs battery questions
Q.How do we open a business account?
One phone call and a fleet list. First job on account can go the same day; formal terms confirmed by email overnight.
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 Kings Heath and the B14 area for this?
Yes. Kings Heath is inside our routine coverage from Oldbury via M6 J6 (Spaghetti Junction), roughly 4 miles from Birmingham. We cover it alongside Birmingham and the surrounding streets.
Q.Can you supply and fit batteries at trade price?
Yes — Yuasa, Varta, Bosch and Exide at proper trade rates for account customers, fitted on your yard with OBD coding included.

Storage fault or supply fault — the tests are different, the costs are different, and guessing is expensive. Every visit here includes the charging check. If you would rather plan it than react to it, a fleet jumpstart can be booked for a time that suits.
