Signs you need this service.
If any of these apply, call with your location and tyre details so availability can be confirmed.
Engine cranks slowly
Sluggish, laboured cranking on a cold morning — the classic first sign a battery is failing.
Clicking, no start
Rapid clicking from the starter solenoid means voltage is too low to engage the motor.
Dashboard warning lights
Battery, ABS, ESP or ECU warnings that flicker on and off point to poor voltage regulation.
Battery age over 4 years
Most start-stop AGM/EFB batteries need replacing every 4–5 years, even without symptoms.
Repeated jump-starts
If you've jump-started more than twice in a month, the battery is finished — not the charging system.
Left lights on overnight
Deep discharges permanently damage lead-acid cells; a jump gets you home but replacement follows.
Why customers choose this service over a garage.
OEM-grade only
Bosch S5/S6, Varta Silver/Blue, Yuasa YBX — batteries that match or exceed the original spec.
BMS coding included
Full battery registration for BMW/Mercedes/Audi/VW/Volvo — critical for start-stop cars.
AGM & EFB stocked
Not all mobile fitters carry the modern chemistries — we do, for every common fitment.
Health check included
Alternator output, parasitic drain and voltage-under-load tested before you're charged for a battery.
How the service actually works.
No garage, no drop-off, no waiting room.
Diagnose first
We test voltage under load, alternator output and parasitic drain before quoting — sometimes it's not the battery.
Match the exact spec
OEM CCA, Ah, terminal position, chemistry (AGM/EFB/flooded) — matched to your car exactly.
Fit & code
Battery installed with electronic memory-saver, terminals torqued, BMS coded on the vehicle diagnostic port.
Verify & photograph
Charging voltage verified, coding confirmed, old battery removed for recycling.

Q · 01How do I know it's the battery and not the alternator?+
The classic sign is a car that starts fine after a jump but dies again overnight — usually a battery. Slow-turning that gets slower with the engine running suggests alternator. We test both before recommending a battery.
Q · 02Do you code the new battery?+
Yes — full BMS coding on BMW, Mercedes, Audi, VW, Volvo, Land Rover and most Kia/Hyundai. Coding is not optional on modern cars.
Q · 03What about EV 12V batteries?+
Yes — Tesla, Kia EV6, Hyundai Ioniq 5 and other EVs use a conventional 12V for accessories. We stock and code these.
