Repeat Flat Batteries — Walmley fleet jumpstart & Diagnosis
Flat again in Walmley? We measure quiescent current and alternator output before selling anyone another battery. Mobile Fleet & Business 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 yard in Walmley sees 3+ battery failures a year, you don't need a garage — you need a mobile partner who prices per job on account and turns up before your morning drops leave.
Fleet vans die from parasitic drain more than anything — trackers, dashcams, tail-lifts, refrigeration. We identify the drain, not just recharge the battery.

Usage patterns that flatten good batteries
Cars left standing on 1970s detached houses for a week or more between uses are the other common case in B76.
Locally that means the streets between Walmley and Sutton Coldfield, with access via A38 Bassetts Pole and A5127 and a practical radius reaching Sutton Coldfield (~2 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.
- Parasitic drain diagnostics standard — trackers, dashcams, refrigeration, tail-lifts, aftermarket wiring
- Fleet & Business 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 Walmley 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.
Where we test
Walmley sits about 2 miles from Sutton Coldfield, and the same van covers Sutton Coldfield (~2 mi), Erdington (~3 mi) and Boldmere (~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 Walmley and the B76 area for this?
Yes. Walmley 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 you do preventative fleet audits?
Yes — quarterly on-site checks: voltage, load test, alternator output, terminal condition on every vehicle. Reports emailed to your fleet manager.
Q.Can you supply and fit batteries at trade price?
Yes — Yuasa, Varta, Bosch and Exide at proper trade rates for account customers, fitted on your yard with OBD coding included.
Flat again?
Third battery in two years is a diagnosis problem. We measure the draw and the charging output before anything is replaced. Same fixed pricing whether it is a fleet jumpstart at 9am or 3am, anywhere in Birmingham City Council.

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 Walmley and the real fault usually appears within the hour. Locally this is handled alongside Sutton Coldfield and Erdington, so the van is rarely far away.
