Disconnecting the 12 V battery on your Lynk & Co 01 (2017–2024) is a straightforward job you might tackle before fitting a new battery, ahead of winter storage, or when you need to work near the airbags and pretensioners. The 01 is built on Volvo’s CMA platform, so the layout under the bonnet is tidy and familiar. Done in the correct order — negative off first, positive on first — the car powers back up and relearns its settings without drama, so a confident owner can do this at home with a single spanner.
Where the 12 V Battery Is
On the Lynk & Co 01 the 12 V battery sits in the engine compartment, following the Volvo CMA layout the car shares. It is usually held down by a clamp and may sit under a plastic cover or trim panel that lifts away. Once you can see it, identify the two terminals: the negative (−), marked with a minus symbol and normally a black lead, and the positive (+), marked with a plus and often protected by a red or coloured cap. Confirm which is which before loosening anything — the order you work in is what keeps the job safe.
Plug-in hybrid models: the PHEV 01 also carries a high-voltage system. Never touch the bright orange high-voltage cabling or connectors. This procedure only ever concerns the ordinary 12 V battery.
Before You Begin
- Make sure the ignition is fully off — and on a PHEV, that the car is not in READY mode — with the doors closed so the electrics settle.
- Take the key fob well away from the car so it cannot wake the systems.
- Switch off the lights, climate, and any accessories, and unplug anything from the 12 V or USB sockets.
- Note down your radio presets and any security code, plus the clock setting, so you can restore them afterwards.
- Wait a couple of minutes after shutting down so the control modules power down.
- Wear gloves and eye protection, and have the correct spanner ready for the terminal clamp nut.
Disconnecting Safely
- Switch everything off, take the key out of range, and wait a couple of minutes for the modules to sleep.
- Lift away any battery cover so you can reach both terminals.
- Slacken and lift off the negative (−) terminal first, then tuck the lead aside so it cannot fall back onto the post.
- Next slacken and remove the positive (+) terminal, and cover the exposed post so it cannot short against bodywork.
- Working near airbags or pretensioners? Wait a few minutes more after disconnecting before you begin.
Reconnecting and Re-initialising
- Refit the positive (+) terminal first and tighten its clamp until it is secure.
- Refit the negative (−) terminal last and tighten it the same way.
- Check both clamps are firm — a loose terminal causes flickering warnings and hard starts.
- Allow the car a minute to wake fully before starting and driving.
What You’ll Need to Reset Afterwards
Removing the 12 V supply clears the short-term memory in several systems. On the 01 you may need to sort out:
- Clock and radio presets — reset the time and re-enter your stations and any audio security code.
- One-touch windows — hold each window switch fully up at the top limit to relearn the auto function, then repeat at the bottom.
- Start/stop and battery management — the 01 runs a stop/start system with an AGM or EFB battery, so its charge-management may take a short settling period, or a drive cycle, before start/stop works normally again.
- Driver and comfort settings — some personalisation may revert to default and need setting again.
- Warning messages — a few dashboard alerts show on first start-up and self-clear after a short drive.
If a Warning Light Stays On or the Car Feels Off
- Re-check that both terminal clamps are tight and clean — a poor connection mimics an electrical fault.
- Take the car for a short, gentle drive to let the systems relearn and clear first-start messages.
- Re-do the window relearn if one-touch or anti-pinch is still not working.
- Rule out a genuinely flat or worn-out battery — if it will not hold charge, disconnection was not the real cause.
- If an alert persists, it has stored a fault code — look it up on autodtcs.com.
Frequently Asked Questions
Where is the battery on a Lynk & Co 01?
In the engine compartment, following the Volvo CMA layout the car is built on. It is usually clamped down and may sit under a plastic cover that lifts away to expose the two terminals.
Which terminal do I disconnect first?
Always take off the negative (−) terminal first and refit it last. Reconnect the positive (+) first when you put things back. That order avoids any risk of a short across the terminals while you work.
Is the plug-in hybrid different?
The PHEV has a separate high-voltage system alongside the ordinary 12 V battery. You still service only the 12 V battery in exactly the same way — just never touch the orange high-voltage cabling.
Do I need to recode anything after fitting a new battery?
A like-for-like AGM or EFB battery of the correct rating does not usually need coding for an owner. Because the 01 has stop/start, the charge-management may simply take a drive cycle or two to settle before start/stop resumes.
Will disconnecting the battery clear stored fault codes?
It can clear some temporary codes and the messages that go with them, but a genuine, ongoing fault will simply log again once the car powers up. If a light comes straight back, read the stored code rather than assuming the battery fixed it.
Can I jump-start it instead of disconnecting?
If the 12 V battery is just flat, a careful jump or boost from another 12 V source can get the car going so you can charge it properly. Only ever connect to the 12 V battery’s own terminals — never the high-voltage system on a PHEV.
If a warning light stays on after reconnecting, look up the code on autodtcs.com.
