Stop-Start Not Working — Wordsley battery replacement & Coding
AGM and EFB batteries in Wordsley cannot be swapped like an old lead-acid unit. We fit, code and verify on-site. Battery Replacement, 24/7 across DY8.
AGM and EFB batteries handle far more charge cycles than a standard flooded unit, which is why manufacturers use them — and why they cost more and need proper handling when they fail.
Battery gone in Wordsley? Rather than driving to a fitting bay and queuing, we come to the vehicle — driveway, workplace car park, or roadside on the A491 corridor.
The wrong battery in a stop-start car will show a warning light within days and drain itself trying to charge to spec. We fit the OEM chemistry every time.
How start-stop failure shows up first
Drivers usually notice the stop-start light staying off for a week or two before any starting trouble appears in DY8.
Locally that means the streets between Wordsley and Stourbridge, with access via A491 and A458 and a practical radius reaching Stourbridge (~2 mi) and Wollaston (~1 mi).
Coding, sensors and correct chemistry
- Replacement batteries are registered to the BMS by capacity and chemistry so the charging strategy matches the new unit.
- AGM units are tested with an AGM-specific profile, because testing one as flooded lead-acid gives a falsely low reading.
- Fixed quoted price including battery, fitting, coding, recycling and warranty registration
- Every battery replacement finishes with a charging-system reading, so the same fault does not reappear next week.

Domestically, 1930s semis and modern estates dominate around here, which shapes how these jobs are accessed and worked.
AGM jobs completed nearby
Recent job nearby: a family SUV in Wordsley with stop-start inactive for a month. AGM tested at 58% state of health, replaced and registered — stop-start active again on the test drive.
Recent job nearby: a car near A491 on its second battery in 14 months. The previous unit had never been coded, which explained the early failure.

AGM and start-stop questions
Q.Will I lose my radio code and seat memory?
No — we use a 12V memory saver on the OBD port during the swap, so all adaptations and settings are preserved.
Q.Do I really need OBD coding when the new battery goes in?
On post-2012 BMW, Audi, VW, Ford, Vauxhall, Peugeot and Citroen — yes. Without coding, the alternator will overcharge the new battery and kill it in under a year.
Q.Why has my stop-start stopped working?
The battery management system disables it when charge acceptance drops. It is a protective measure, and normally the earliest warning of an AGM battery reaching the end of its life.
Q.Can I fit a normal battery instead of an AGM one?
Not on a vehicle designed for AGM. The charging voltage and cycling regime will destroy a standard flooded battery quickly, and stop-start will stay disabled.
Q.Do you code the battery on-site during a battery replacement?
Yes — registration is done in the van with the diagnostic tool before we leave, and we confirm the new profile has taken.
Q.Do you cover Wordsley and the DY8 area for this?
Yes. Wordsley is inside our routine coverage from Oldbury via A491, roughly 2 miles from Stourbridge. We cover it alongside Stourbridge and the surrounding streets.
Nearby areas covered
Working out from DY8, the practical radius for a battery replacement takes in Stourbridge, Wollaston, Amblecote and Wordsley — all within a few minutes of A491.

AGM done properly, on your drive
Correct chemistry, correct capacity, registered to the car's BMS before we leave Wordsley. We route in via A491, roughly 2 miles out from Stourbridge.
The short version
Start-stop vehicles need a battery that matches the car's charging strategy and a BMS that knows the battery has changed. Get both right in Wordsley and the replacement lasts as long as it should. Locally this is handled alongside Stourbridge and Wollaston, so the van is rarely far away.
