Repeat Flat Batteries — Mere Green van jumpstart & Diagnosis
Flat again in Mere Green? We measure quiescent current and alternator output before selling anyone another battery. Mobile Van Jumpstart, 24/7.
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.
If your work van is stone dead around Mere Green, 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.
Diesel vans need real cranking amps — a jump pack designed for cars won't spin a 2.0 or 2.2 diesel that's been standing cold. Our kit is spec'd for commercials.
How a drain is actually traced
- Circuits are isolated fuse by fuse to locate the offending module rather than guessing at the usual suspects.
- Quiescent draw is measured after the vehicle's modules have gone to sleep, which can take 20–40 minutes — measuring too early gives a false high reading.
- Battery registration/coding done on the OBD for vans that need it (Sprinter, Crafter, T6, Custom)
- Every van jumpstart finishes with a charging-system reading, so the same fault does not reappear next week.
Drain faults found nearby
Recent job nearby: a car in Mere Green 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.

Usage patterns that flatten good batteries
Cars left standing on large detached houses for a week or more between uses are the other common case in B75.
Locally that means the streets between Mere Green and Sutton Coldfield, with access via A38 Bassetts Pole and A5127 and a practical radius reaching Sutton Coldfield (~2 mi) and Erdington (~3 mi).
Where we test
Working out from B75, the practical radius for a van jumpstart takes in Sutton Coldfield, Erdington, Boldmere and Streetly — all within a few minutes of A38 Bassetts Pole.

Repeat flat battery questions
Q.Do you cover Mere Green and the B75 area for this?
Yes. Mere Green is inside our routine coverage from Oldbury via A38 Bassetts Pole, roughly 2 miles from Sutton Coldfield. We cover it alongside Sutton Coldfield and the surrounding streets.
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.Can you invoice a fleet directly?
Yes — 30-day account terms and single monthly invoice for multi-vehicle operators. Just send us the fleet list.
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.
Stop buying batteries. Find the drain.
Proper quiescent current testing in Mere Green, with the offending circuit identified rather than guessed. Tell us the vehicle and the symptom and you will get a firm price before anyone sets off.
Why this is safe to book
- Findings are written down with the actual current draw in milliamps, so any follow-up work starts from evidence.
- Fixed prices agreed before dispatch — no callout fee just to open the bonnet in B75.

The short version
A battery that keeps dying is telling you about the car, not about itself. Measure the sleep draw and the charging voltage in Mere Green and the real fault usually appears within the hour. If you would rather plan it than react to it, a van jumpstart can be booked for a time that suits.
