Repeat Flat Batteries — Walsgrave emergency jumpstart & Diagnosis
New battery still going flat in Walsgrave? That is a parasitic drain or charging fault, not a bad battery. Drain testing plus emergency jumpstart on-site.
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.
Emergency jumpstart cover across Walsgrave — Christmas Day, New Year's Eve, 4am on a Tuesday, we answer the phone and dispatch straight from Oldbury.
Off-peak, we don't queue behind a hundred other members. One call, one van, one job — you're not number 87 in a queue.
Drain faults found nearby
Recent job nearby: a car in Walsgrave 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 J2/J3 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.
- Genuine 24/7 — nights, weekends, Christmas Day, New Year — same price as daytime
- On a emergency jumpstart the equipment is matched to the vehicle — cranking current, terminal layout and battery location all change the approach.
Usage patterns that flatten good batteries
Cars left standing on post-war estates for a week or more between uses are the other common case in CV2.
Locally that means the streets between Walsgrave and Coventry, with access via M6 J2/J3 and M69 and a practical radius reaching Coventry (~3 mi) and Nuneaton (~9 mi).
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 J2/J3, roughly 3 miles out from Coventry.
Repeat flat battery questions
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 Walsgrave and the CV2 area for this?
Yes. Walsgrave is inside our routine coverage from Oldbury via M6 J2/J3, roughly 3 miles from Coventry. We cover it alongside Coventry and the surrounding streets.
Q.What if my car is in a locked car park overnight?
Tell us on the call — usually a security guard or manager can let us in. We've done this in NCPs, hospital car parks and industrial estates dozens of times.
Q.Do you really answer at 3am?
Yes — a real person answers, not an out-of-hours message service. If we're on a job we call back within 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.
Who this page is for
Low-mileage drivers whose cars sit for days between short journeys.

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.

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 Walsgrave and the real fault usually appears within the hour. Locally this is handled alongside Coventry and Nuneaton, so the van is rarely far away.
