Mobile van jumpstart · Battery keeps going flat
Why Your Battery Keeps Dying — Van Jumpstart, Streetly
Flat again in Streetly? We measure quiescent current and alternator output before selling anyone another battery. Mobile Van Jumpstart, 24/7.
Repeat flat batteries are a diagnostic job, not a parts job. The measurement takes longer than the fix usually does.
If your work van is stone dead around Streetly, don't book recovery yet. Most van no-starts near the A38 Bassetts Pole corridor are cured with a mobile jump and a proper alternator/battery health check on the driveway.
We cover the B74 area regularly for trade customers running Ford Transits, Mercedes Sprinters, VW Transporters, Vauxhall Vivaros, Renault Trafics and Peugeot Boxers.
Usage patterns that flatten good batteries
Cars left standing on 1930s detached houses for a week or more between uses are the other common case in B74.
Locally that means the streets between Streetly and Sutton Coldfield, with access via A38 Bassetts Pole and A5127 and a practical radius reaching Sutton Coldfield (~3 mi) and Erdington (~3 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.
- We check tail-lift, refrigeration, dashcam and tracker draw for parasitic drain that kills fleet batteries
- Van Jumpstart work here is judged against the vehicle's own specification rather than a generic pass mark.

Drain faults found nearby
Recent job nearby: a car in Streetly 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 A38 Bassetts Pole flattening weekly. Alternator produced 13.1V under load — replaced the charging fault, kept the original battery.

Repeat flat battery questions
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.
Q.Do you cover Streetly and the B74 area for this?
Yes. Streetly is inside our routine coverage from Oldbury via A38 Bassetts Pole, roughly 3 miles from Sutton Coldfield. We cover it alongside Sutton Coldfield 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.
Where we test
Streetly sits about 3 miles from Sutton Coldfield, and the same van covers Sutton Coldfield (~3 mi), Erdington (~3 mi) and Boldmere (~1 mi) on the same run.
Why this is safe to book
- We will not sell a battery to a car whose battery is not the fault.
- Old batteries removed and recycled on every van jumpstart.

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. Either way you get the readings, the reasoning and a working vehicle before we leave.
