Auxiliary 12VFit at the curb
When to call this in
Signs this is the right service.
- The car needs a jump more than once in a week
- Cold mornings leave you with a dead screen or a no-start
- A battery test shows low cranking capacity or high internal resistance
- An aging auxiliary battery is about to strand you and you would rather not wait
How it works
What happens after you call.
- 01
Confirm the spec
Group size, terminal layout, amp-hour rating and any registration requirement for your model — checked before we load a battery.
- 02
Test the old one
We load-test and read the charging voltage so we know the battery is the problem rather than the alternator or DC-DC converter.
- 03
Fit the new one
Swapped at the curb, terminals cleaned and protected, hold-down torqued, memory and window settings restored where we can.
- 04
Register and dispose
Battery registration is done where the vehicle requires it, and we take the old battery away for recycling.
What is included
- A matching auxiliary battery brought to you
- Load test and charging-system reading before the swap
- Fitting, terminal clean-up and hold-down torque
- Old battery removal and recycling
What is not
- Traction (high-voltage) battery diagnosis or replacement
- Dealer-only module programming
- Batteries for vehicles whose spec we cannot source at the time
Questions about battery exchange
Straight answers.
Is this the big battery?
No. This is the 12-volt auxiliary battery, the same idea as a gas car battery. Traction pack work is dealer territory and we do not touch it.
Why does an EV even have a 12-volt battery?
It runs the computers, lights, locks and the contactors that connect the traction pack. When it dies the car behaves as if it is completely dead.
Do I need to register the new battery?
Some German and Korean models require it so the charging system adapts. We do it where the tooling allows, and tell you if a dealer visit is needed.
How long will the new battery last?
Typically three to five years depending on climate and how the car is used. Hot climates shorten it, and so does lots of short-trip cycling.
Can you fit a battery I bought myself?
Yes, though we cannot warranty a part we did not supply. Fitting only is quoted on the call.
