Battery Keeps Going Flat in Blackheath? Drain Testing & Van Jumpstart
Flat again in Blackheath? We measure quiescent current and alternator output before selling anyone another battery. Mobile Van Jumpstart, 24/7.
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.
A dead Transit, Sprinter, Vivaro or Crafter on a B65 driveway usually isn't a garage job. A proper mobile jumpstart with a 2000A+ pack gets you running in minutes without a recovery truck.
Around Blackheath 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
We see this pattern often with cars used for short journeys around Blackheath — a 10-minute trip never replaces the charge that starting consumed, so the battery slowly sinks regardless of health.
Locally that means the streets between Blackheath and Rowley Regis, with access via A4123 and A459 and a practical radius reaching Rowley Regis (~1 mi) and Blackheath (~1 mi).
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.
- 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.
Who this page is for
Low-mileage drivers whose cars sit for days between short journeys.
Domestically, high-street flats and 1930s semis dominate around here, which shapes how these jobs are accessed and worked.
Why this is safe to book
- We will not sell a battery to a car whose battery is not the fault.
- Fully insured for work on driveways, business premises and private car parks across Sandwell Metropolitan Borough Council.
Drain faults found nearby
Recent job nearby: a car in Blackheath 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 A4123 flattening weekly. Alternator produced 13.1V under load — replaced the charging fault, kept the original battery.
Where we test
Blackheath sits about 1 miles from Rowley Regis, and the same van covers Rowley Regis (~1 mi), Blackheath (~1 mi) and Cradley Heath (~1 mi) on the same run.
Repeat flat battery questions
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.
Q.Do you cover Blackheath and the B65 area for this?
Yes. Blackheath is inside our routine coverage from Oldbury via A4123, roughly 1 miles from Rowley Regis. We cover it alongside Rowley Regis 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.My van cranks slowly then dies — is that the battery?
Usually yes, but sometimes it's the starter drawing too much current or a bad earth. We test all three on the driveway before recommending a replacement.

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.
