Tried Jump Leads And Still Nothing — Coundon battery replacement
Jump leads failed in Coundon? Thin leads and small donor cars often cannot deliver the current needed. Professional battery replacement with proper equipment.
Consumer jump leads often use 8mm² cable where a professional set uses 25mm² or more. On a cold diesel that difference is the entire job: the current simply cannot get through.
If your battery in Coundon is more than 4 years old and keeps going flat, you're past jumpstart territory — you need a proper replacement, fitted and coded on your driveway.
Stock on the van covers every popular fitment: standard flooded 063/096/075/100, EFB start-stop, and AGM 019/017 for premium and stop-start applications.
Why home attempts fail
We are often called after a neighbour has had a go on a CV6 street — which is generous but rarely equipped for a genuinely flat battery.
Locally that means the streets between Coundon and Coventry, with access via M6 J2/J3 and M69 and a practical radius reaching Coventry (~2 mi) and Nuneaton (~9 mi).
Who calls after a failed attempt
Drivers in Coundon who have already tried and want it done with proper equipment.
Domestically, 1930s semis and modern estates dominate around here, which shapes how these jobs are accessed and worked.

Repeated attempts can do real damage. Proper equipment and a measurement first, anywhere in Coundon. Same fixed pricing whether it is a battery replacement at 9am or 3am, anywhere in Coventry City Council.
Current, cable and contact
- Any damage from an incorrect attempt, such as a blown main fuse from reversed polarity, is identified rather than overlooked.
- If the vehicle stays dead on professional equipment, the fault is not the battery — starter, solenoid, immobiliser or earth become the focus.
- Fixed quoted price including battery, fitting, coding, recycling and warranty registration
- Every battery replacement finishes with a charging-system reading, so the same fault does not reappear next week.
Failed jumpstart questions
Q.Will I lose my radio code and seat memory?
No — we use a 12V memory saver on the OBD port during the swap, so all adaptations and settings are preserved.
Q.Why didn't the jump leads work?
Usually inadequate cable gauge, poor contact on a corroded terminal, or a donor vehicle too small to supply the current. Occasionally the fault simply is not the battery.
Q.Could I have damaged the car trying?
Reversed polarity can blow main fuses or damage electronics. It is worth checking, and we do that as part of the visit.
Q.What will you do differently?
Measure first, then apply several hundred amps through proper cable at clean contact points — and if it still will not start, tell you precisely what the fault is instead.
Q.Do you cover Coundon and the CV6 area for this?
Yes. Coundon is inside our routine coverage from Oldbury via M6 J2/J3, roughly 2 miles from Coventry. We cover it alongside Coventry and the surrounding streets.
Q.How do I know my battery needs replacing rather than jumpstarting?
If it's over 4 years old and going flat repeatedly, or the CCA on a load tester reads under 60% of rated, it's replacement time. Jumpstarting will only get you a day or two.
