Motorhome & Campervan Battery Replacement in Knowle
Knowle motorhome callouts — split charge relays, leisure banks and starter batteries diagnosed on-site. Battery Replacement, 24/7.
Leisure vehicles have two electrical worlds that people routinely confuse. The starter battery turns the engine; the leisure bank runs the fridge, lights and water pump. A fault in one produces symptoms that look like the other.
Mobile battery replacement across Knowle and the B93 area, with the correct AGM, EFB or standard flooded chemistry fitted the first time — not whatever's on the shelf.
Knowle covers a mix of buildings and driveways — large detached houses, village-centre cottages — and we're set up to work in all of them, including tight residential streets.
Storage, standing and split charging
Around Knowle these callouts come from driveways and storage compounds where vehicles sit between trips, especially over winter.
Locally that means the streets between Knowle and Solihull, with access via M42 J4/J5 and A34 Stratford Road and a practical radius reaching Solihull (~4 mi) and Shirley (~2 mi).
Testing two systems properly
- Where the vehicle is going back into storage, solar and maintenance charging options are discussed.
- Leisure batteries are deep-cycle by design and are tested on a cyclic profile rather than a cranking profile.
- Memory saver used during change so radio codes, seat memories and ECU adaptations are preserved
- Battery Replacement work here is judged against the vehicle's own specification rather than a generic pass mark.

Motorhome battery questions
Q.My engine starts but the fridge and lights are dead. Which battery is it?
The leisure bank, or the split charge system that feeds it. The starter battery is clearly fine if the engine turns over.
Q.Can I use a starter battery as a leisure battery?
Not sensibly. Starter batteries hate deep discharge and will fail quickly in a habitation role; leisure batteries are built for exactly that cycling.
Q.Do you attend storage compounds?
Yes, provided you can arrange access. Tell us the gate arrangements when you book so the visit is not wasted.
Q.Do you cover Knowle and the B93 area for this?
Yes. Knowle is inside our routine coverage from Oldbury via M42 J4/J5, roughly 4 miles from Solihull. We cover it alongside Solihull 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.
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.
Where we attend
As a neighbourhood of Solihull, Knowle is covered alongside its parent town, so a motorhome and leisure vehicles call from any of them routes to the same engineer.
Why this is safe to book
- Both electrical systems tested and reported separately, so the actual fault is clear.
- Fixed prices agreed before dispatch — no callout fee just to open the bonnet in B93.

Getting ready for a trip?
Have both banks and the split charge system checked before you set off rather than at a campsite. We route in via M42 J4/J5, roughly 4 miles out from Solihull.
The short version
Starter, leisure and split charge — check all three and a motorhome electrical fault stops being a mystery. Locally this is handled alongside Solihull and Shirley, so the van is rarely far away.
