Disconnecting the 12 V battery on a Nissan Micra Mk5 (K14, 2017–present) is a straightforward engine-bay job. This guide covers safe disconnection and re-teaching the one-touch windows afterwards.
Where the Battery Is
The 12 V battery is in the engine compartment, under a cover.
Disconnecting
- Switch the ignition off and keep the Intelligent Key away from the car; give the electronics a couple of minutes to power down.
- Disconnect the negative (−, black) terminal first and lift the lead clear.
- If removing the battery, disconnect the positive (+, red) next, then the hold-down.
Airbag/pretensioner safety: if you’ll be near airbags or seat-belt pretensioners, allow the system to discharge for a couple of minutes.
Reconnecting & Re-teaching
- Reconnect positive (+) first, then negative (−) last; tighten and refit the cover.
- Reset the clock and re-enter radio presets.
- Re-initialise the power windows — one-touch drops out after a power cut. See our Micra window guide.
The Micra doesn’t need the new battery coded.
Frequently Asked Questions
Which terminal first on the Micra?
Always the negative (−) first, and reconnect it last.
Does it need the battery registered?
No — just fit it and re-teach the windows.
Will I lose my radio?
The Micra’s media usually isn’t code-locked; just reset the clock.
Why won’t my windows auto-close after this?
Cutting power clears their learned position. Run the quick re-initialise.
For any warning light that stays on, look up the code on autodtcs.com. To clear the service reminder, see our Micra Mk5 service reset guide.
