Motorhome & Campervan Battery Replacement in Selly Oak
Selly Oak 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 Selly Oak and the B29 area, with the correct AGM, EFB or standard flooded chemistry fitted the first time — not whatever's on the shelf.
A properly registered AGM battery in a BMW, Audi or VW will last 6–8 years. A flooded battery dropped in without coding, in the same car, will fail in under 2.

Storage, standing and split charging
Around Selly Oak these callouts come from driveways and storage compounds where vehicles sit between trips, especially over winter.
Locally that means the streets between Selly Oak and Birmingham, with access via A38 Bristol Road and a practical radius reaching Birmingham (~3 mi) and Smethwick (~3 mi).
Testing two systems properly
- Leisure batteries are deep-cycle by design and are tested on a cyclic profile rather than a cranking profile.
- Split charge relays and DC-DC chargers are checked for output while the engine runs.
- OBD battery registration for BMW, Audi, VW, Mercedes, Ford, Vauxhall, Peugeot, Citroen — included in the fit price
- Battery Replacement work here is judged against the vehicle's own specification rather than a generic pass mark.
Owners we help
Owners of converted vans with self-installed leisure systems that have stopped charging.
Domestically, student HMOs and Victorian terraces dominate around here, which shapes how these jobs are accessed and worked.

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 Selly Oak and the B29 area for this?
Yes. Selly Oak is inside our routine coverage from Oldbury via A38 Bristol Road, roughly 3 miles from Birmingham. We cover it alongside Birmingham 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.

The short version
Leisure vehicles fail in two different ways and the symptoms overlap. Testing both banks and the charging link in Selly Oak separates them in one visit. If you would rather plan it than react to it, a battery replacement can be booked for a time that suits.
