Mobile car jumpstart · Battery keeps going flat
Repeat Flat Batteries — Rowley Regis car jumpstart & Diagnosis
Flat again in Rowley Regis? We measure quiescent current and alternator output before selling anyone another battery. Mobile Car 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.
Around Rowley Regis we jumpstart cars every day — from tiny Fiat 500s outside terraces on B65, up to big Range Rovers and BMW X5s with dual AGM setups.
Local roads like the A4123 and A459 mean we can get to most Rowley Regis addresses within the hour, day or night.
Usage patterns that flatten good batteries
Cars left standing on terraced hillside streets for a week or more between uses are the other common case in B65.
Locally that means Rowley Regis itself plus the neighbourhoods that feed into it, with access via A4123 and A459 and a practical radius reaching Blackheath (~1 mi) and Cradley Heath (~1 mi).
Who this page is for
Low-mileage drivers whose cars sit for days between short journeys.
Domestically, terraced hillside streets and 1930s semis dominate around here, which shapes how these jobs are accessed and worked.

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.
- Alternator output measured at idle and at load so you know if a 20-minute drive will actually refill the battery
- Car Jumpstart work here is judged against the vehicle's own specification rather than a generic pass mark.
Repeat flat battery questions
Q.How long should I drive after a jumpstart?
Ideally 30–45 minutes of continuous driving, not stop-start town use. But if the battery is old and the alternator can't get it above 12.6V at rest, it'll go flat again in days.
Q.How long does a car jumpstart take?
From arrival, most jobs are done in 15–20 minutes including a full electrical health check. If we're fitting a new battery we're usually finished inside 40 minutes.
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 Rowley Regis and the B65 area for this?
Yes. Rowley Regis is inside our routine coverage from Oldbury via A4123, roughly 2 miles from Oldbury. We also cover the surrounding neighbourhoods on the same run.
Drain faults found nearby
Recent job nearby: a car in Rowley Regis 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.
Stop buying batteries. Find the drain.
Proper quiescent current testing in Rowley Regis, with the offending circuit identified rather than guessed. Ask for a car jumpstart and quote your postcode — B65 is a routine run for us.
Where we test
Working out from B65, the practical radius for a car jumpstart takes in Blackheath, Cradley Heath, Old Hill and Tividale — all within a few minutes of A4123.

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 Rowley Regis and the real fault usually appears within the hour. If you would rather plan it than react to it, a car jumpstart can be booked for a time that suits.
