Battery Keeps Going Flat in Erdington? Drain Testing & Fleet & Business Jumpstart
Flat again in Erdington? We measure quiescent current and alternator output before selling anyone another battery. Mobile Fleet & Business 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.
If your yard in Erdington 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.
professional services, hospitality, retail operators in Erdington are our regulars — we build a vehicle list against your account so future calls are one text: reg + address.
Usage patterns that flatten good batteries
Cars left standing on 1930s semis for a week or more between uses are the other common case in B23.
Locally that means the streets between Erdington and Birmingham, with access via M6 J6 (Spaghetti Junction) and A38(M) Aston Expressway and a practical radius reaching Birmingham (~4 mi) and Smethwick (~3 mi).
Who this page is for
Owners in Erdington on their second or third battery for the same vehicle.
Domestically, 1930s semis and high-street flats dominate around here, which shapes how these jobs are accessed and worked.
Flat again?
Third battery in two years is a diagnosis problem. We measure the draw and the charging output before anything is replaced. We route in via M6 J6 (Spaghetti Junction), roughly 4 miles out from Birmingham.

How a drain is actually traced
- 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.
- Charge acceptance is tested, because a sulphated battery can read 12.6V and still hold almost no usable energy.
- Vehicle register held on file — one call gives us the reg, spec, battery history and yard location
- Fleet & Business Jumpstart work here is judged against the vehicle's own specification rather than a generic pass mark.
Repeat flat battery questions
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.
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 Erdington and the B23 area for this?
Yes. Erdington is inside our routine coverage from Oldbury via M6 J6 (Spaghetti Junction), roughly 4 miles from Birmingham. We cover it alongside Birmingham 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.
Drain faults found nearby
Recent job nearby: a car in Erdington 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 M6 J6 (Spaghetti Junction) flattening weekly. Alternator produced 13.1V under load — replaced the charging fault, kept the original battery.
Where we test
