Battery Keeps Going Flat in Bromsgrove? Drain Testing & Van Jumpstart
New battery still going flat in Bromsgrove? That is a parasitic drain or charging fault, not a bad battery. Drain testing plus van jumpstart on-site.
Buying a second battery for the same car in a year is the clearest sign the first one was never the problem. Something is either draining charge while the car sleeps, or failing to put it back while the car runs.
Commercial vans park up cold overnight in Bromsgrove 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.
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.
Drain faults found nearby
Recent job nearby: a car in Bromsgrove 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 M5 J4/J4A flattening weekly. Alternator produced 13.1V under load — replaced the charging fault, kept the original battery.
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.
Usage patterns that flatten good batteries
Cars left standing on market-town centres for a week or more between uses are the other common case in B60.
Locally that means Bromsgrove itself plus the neighbourhoods that feed into it, with access via M5 J4/J4A and M42 J1 and a practical radius reaching Barnt Green (~3 mi) and Catshill (~2 mi).
Repeat flat battery questions
Q.Do you cover Bromsgrove and the B60 area for this?
Yes. Bromsgrove is inside our routine coverage from Oldbury via M5 J4/J4A, roughly 13 miles from Birmingham. We also cover the surrounding neighbourhoods on the same run.
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.
Stop buying batteries. Find the drain.
Proper quiescent current testing in Bromsgrove, with the offending circuit identified rather than guessed. Ask for a van jumpstart and quote your postcode — B60 is a routine run for us.
Who this page is for
Low-mileage drivers whose cars sit for days between short journeys.
Domestically, market-town centres and 1930s semis dominate around here, which shapes how these jobs are accessed and worked.
How the visit runs

How a drain is actually traced
Circuits are isolated fuse by fuse to locate the offending module rather than guessing at the usual suspects.
- 2
Phone diagnosis
Van make, model, engine size and symptom — we already know if it's a battery, alternator or starter pattern.
- 3
Fixed quote
Price agreed before we set off. Includes callout, jumpstart and full electrical health check.
- 4
On-site test
Voltage, load, alternator output at 2000 rpm, parasitic draw. Real numbers, not guesses.
Where we test
Bromsgrove sits about 13 miles from Birmingham, and the same van covers Barnt Green (~3 mi), Catshill (~2 mi) and Wythall (~5 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.
- Fixed prices agreed before dispatch — no callout fee just to open the bonnet in B60.

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 Bromsgrove and the real fault usually appears within the hour. For van jumpstart specifically, that means heavy-duty 2000a+ lithium jump pack rated for diesel commercials up to 7.5t
