Business account service · Start-stop and AGM systems
Stop-start disabled or AGM battery failing in Erdington? Replacement requires battery registration to the BMS. Mobile fleet jumpstart with coding included.

Start-stop vehicles run a battery management system that tracks charge acceptance over time. Fit a new battery without registering it and the BMS keeps charging to the old profile, which cooks a new AGM unit in months.
Running a fleet out of Erdington? A dead battery in one van costs a full day of missed drops, angry customers and a driver stood around. We keep West Midlands fleets moving with priority callout and account billing.
We invoice monthly with full PDF breakdown per vehicle — clean for accounts to file, VAT-compliant, no per-job card fiddling.
Recent job nearby: a family SUV in Erdington 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 M6 J6 (Spaghetti Junction) on its second battery in 14 months. The previous unit had never been coded, which explained the early failure.
AGM units are tested with an AGM-specific profile, because testing one as flooded lead-acid gives a falsely low reading.
One call, one fleet list, account live the same day for first callouts.
Driver quotes the fleet reference; no card payment, no per-job admin.
Account jobs go ahead of retail callouts, typical arrival 30–45 minutes.
That warning is worth acting on. We test with an AGM profile and carry matched stock on the van. Ask for a fleet jumpstart and quote your postcode — B23 is a routine run for us.
Newer vehicles are common on 1930s semis around Erdington, so a decent share of our work here involves coding rather than just lifting a battery in and out.
Locally that means the streets between Erdington 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).
Erdington sits about 4 miles from Birmingham, and the same van covers Birmingham (~4 mi), Smethwick (~3 mi) and Sutton Coldfield (~7 mi) on the same run.
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.
One phone call and a fleet list. First job on account can go the same day; formal terms confirmed by email overnight.
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.
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.
Yes — registration is done in the van with the diagnostic tool before we leave, and we confirm the new profile has taken.
Yes. Erdington 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.
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 Erdington and the replacement lasts as long as it should. For fleet jumpstart specifically, that means single monthly invoice, vat-compliant, per-vehicle breakdown ready for your fleet accountant
