Motorhomes are two vehicles in one: a base van (usually Ducato, Boxer, Sprinter or Transit) with a starter battery, and a habitation area running on a leisure battery through a split-charge or DC-DC system.
'Won't start' after a weekend away is often a failed split-charge relay draining the starter into the habitation, we diagnose the actual circuit fault before selling you a battery.
Key facts, Motorhomes & campers
- Starter battery
- Base van spec, Ducato, Sprinter, Transit, Boxer
- Leisure battery
- AGM 90 to 110Ah or lithium LiFePO4
- Common fault
- Split-charge relay stuck closed or fuse blown
- Access
- Often under a bench, wardrobe or driver's seat
What we actually see on these jobs
- We test both circuits, starter and leisure, before selling anything.
- Storage over winter with a solar trickle can mask a failing battery until spring; we spot the pattern.
- We work at storage compounds and driveways alike, discreetly, no clanging around a caravan site at 2am.
Who calls us for this
Owners on a Friday evening loading up for the weekend, buyers collecting a used motorhome from a dealer, and storage-compound customers pulling a van out after winter.
How the callout works
- 1
One call, one price
Postcode, vehicle and symptom on the phone, you get a fixed price before we set off.
- 2
On-site test
Voltage, load and (where relevant) alternator field test at your location.
- 3
Jumpstart or replace
If it holds, you drive off. If it doesn't, we fit the correct battery from van stock.
- 4
Coded and warrantied
BMS coding included where required, warranty paperwork by email before we leave.
Motorhomes & campers, specific questions
Q.Do you test the leisure battery as well?
Yes, it's usually the real issue behind a 'starter battery' complaint after a week off-grid.
Q.Can you fit lithium (LiFePO4) leisure batteries?
We can advise, but a lithium leisure install is a workshop job, we handle the immediate starter-battery fix and refer you if a full lithium changeover is needed.
Q.Will you come to a storage compound?
Yes, West Midlands and surrounding counties routinely. Just make sure you have gate access sorted.
General questions
Q.Can you invoice on account for businesses?
Yes, 30-day account terms available for fleets, lettings, dealers and repeat trade customers. Single monthly PDF invoice.
Q.Do you take the old battery away?
Yes, proper lead-acid recycling included with every fit, no extra charge, no landfill.
Q.Do you code new batteries to the vehicle?
Yes, wherever the manufacturer requires it, BMW, Audi, VW, Mercedes, Ford, Vauxhall, Peugeot/Citroen. OBD-level coding included with every fit that needs it.

In short
Motorhome jobs are diagnostic jobs, we work out which circuit is really at fault before we replace anything, and that saves you buying batteries you don't need.
