Motorhome & Campervan Battery Replacement in Shirley
Shirley 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 Shirley and the B90 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.
Testing two systems properly
- Split charge relays and DC-DC chargers are checked for output while the engine runs.
- Starter and leisure banks are tested independently, because a healthy engine battery tells you nothing about the habitation side.
- Correct chemistry every time: flooded / EFB / AGM matched to what the manufacturer specified
- On a battery replacement the equipment is matched to the vehicle — cranking current, terminal layout and battery location all change the approach.
Storage, standing and split charging
Around Shirley these callouts come from driveways and storage compounds where vehicles sit between trips, especially over winter.
Locally that means the streets between Shirley and Solihull, with access via M42 J4/J5 and A34 Stratford Road and a practical radius reaching Solihull (~2 mi) and Shirley (~2 mi).
Getting ready for a trip?
Have both banks and the split charge system checked before you set off rather than at a campsite. Battery Replacement covers 1930s semis and retail-park units and trade vehicles alike, all from the same van.
Owners we help
Owners of converted vans with self-installed leisure systems that have stopped charging.
Domestically, 1930s semis and retail-park units dominate around here, which shapes how these jobs are accessed and worked.

Motorhome battery questions
Q.Do you cover Shirley and the B90 area for this?
Yes. Shirley is inside our routine coverage from Oldbury via M42 J4/J5, roughly 2 miles from Solihull. We cover it alongside Solihull and the surrounding streets.
Q.Do I really need OBD coding when the new battery goes in?
On post-2012 BMW, Audi, VW, Ford, Vauxhall, Peugeot and Citroen — yes. Without coding, the alternator will overcharge the new battery and kill it in under a year.
Q.What's the difference between AGM and EFB?
AGM is a fully sealed absorbed-glass-mat battery for premium and stop-start; EFB is an enhanced flooded battery for entry-level stop-start. Fitting the wrong one is a warranty-void job.
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.
How the visit runs
- 1
Testing two systems properly
Where the vehicle is going back into storage, solar and maintenance charging options are discussed.
- 2
Vehicle lookup
By reg on the phone — we confirm the exact OEM battery spec before quoting.
- 3
Fixed all-in price
Battery, fitting, coding, recycling, warranty — one number on the phone.
- 4
Driveway fit
Memory saver in, old battery out, new one in and terminals torqued to spec.
Why this is safe to book
- Larger vehicles and restricted-access compounds are routine work, not an exception.
- Old batteries removed and recycled on every battery replacement.
Where we attend
Shirley sits about 2 miles from Solihull, and the same van covers Solihull (~2 mi), Shirley (~2 mi) and Olton (~2 mi) on the same run.

The short version
Leisure vehicles fail in two different ways and the symptoms overlap. Testing both banks and the charging link in Shirley separates them in one visit. For battery replacement specifically, that means memory saver used during change so radio codes, seat memories and ecu adaptations are preserved
