Repeat Flat Batteries — Wollaston van jumpstart & Diagnosis
New battery still going flat in Wollaston? That is a parasitic drain or charging fault, not a bad battery. Drain testing plus van jumpstart on-site.
A healthy vehicle should draw around 20–50 milliamps once everything has gone to sleep. A faulty module, an aftermarket alarm or a stuck relay can pull ten times that, which flattens a good battery in two or three days.
Commercial vans park up cold overnight in Wollaston and refuse to start when the temperature drops. That's parasitic drain plus an ageing battery — a jumpstart on the spot beats a tow every time.
Around Wollaston the common jobs are morning no-starts on the yard, lunch-break dead batteries at customer sites, and end-of-day flatlines after tail-lift or refrigeration use.
Usage patterns that flatten good batteries
Cars left standing on Victorian terraces for a week or more between uses are the other common case in DY8.
Locally that means the streets between Wollaston and Stourbridge, with access via A491 and A458 and a practical radius reaching Stourbridge (~1 mi) and Wollaston (~1 mi).
How a drain is actually traced
- Alternator output is checked under electrical load with headlights, blower and heated screen on, not just at idle.
- Circuits are isolated fuse by fuse to locate the offending module rather than guessing at the usual suspects.
- AGM and EFB stop-start vans handled correctly — no fitting a standard flooded battery in an AGM slot
- Every van jumpstart finishes with a charging-system reading, so the same fault does not reappear next week.

Low-mileage drivers whose cars sit for days between short journeys.
Domestically, Victorian terraces and 1930s semis dominate around here, which shapes how these jobs are accessed and worked.
Drain faults found nearby
Recent job nearby: a car in Wollaston on its third battery in two years. Drain measured at 480mA, traced to a boot latch microswitch keeping a module awake.
Recent job nearby: a vehicle off A491 flattening weekly. Alternator produced 13.1V under load — replaced the charging fault, kept the original battery.

Repeat flat battery questions
Q.Do you cover Wollaston and the DY8 area for this?
Yes. Wollaston is inside our routine coverage from Oldbury via A491, roughly 1 miles from Stourbridge. We cover it alongside Stourbridge and the surrounding streets.
Q.What if the van battery keeps going flat every week?
That's parasitic drain — usually a dashcam, tracker or aftermarket electrics wired to permanent live. We do a milliamp draw test and identify the circuit.
Q.Do I need to register a new van battery to the ECU?
On Sprinters, Crafters, T6 Transporters and newer Custom Transits — yes. We carry the OBD tool and code it as part of the fit.
Q.Is a parasitic drain always an electrical fault?
No. Sometimes it is an aftermarket dashcam, tracker or alarm wired to a permanent live. Those are the easy wins and we find them first.
Q.How long does drain testing take?
Allow around an hour. Most of that is waiting for the vehicle's modules to sleep — rushing it produces a meaningless number.
Q.Could short journeys alone be the cause?
Yes, and it is more common than people expect. If that is what the readings show, the fix is a conditioning charge and a change in usage, not another battery.

The short version
Repeat failures are solved with a meter, not a parts catalogue. Find the drain, fix the cause, and the next battery lasts its full life. That is the whole job: diagnose it properly, fix it once, and explain what caused it.
