Disconnecting the 12 V battery on a Nissan Juke Mk2 (F16, 2019–present) is a normal engine-bay job, with one Nissan-specific quirk: the car wants a notably long wait (around 12 minutes) after switch-off before you pull the power, so its modules go fully to sleep. This guide covers the safe sequence and what to restore afterwards.

Where the Battery Is

The 12 V battery sits in the engine compartment, under a cover. (This guide is for the petrol Juke; the 2022-on full-hybrid has extra high-voltage hardware that is workshop-only — only the 12 V is owner-serviceable.)

Disconnecting

  1. Switch the ignition off, remove the Intelligent Key from the car, close the doors and wait about 12 minutes for the electronics to power down.
  2. Open the bonnet and disconnect the negative (−, black) terminal first, lifting the lead clear.
  3. If removing the battery, disconnect the positive (+, red) next, then the hold-down clamp.

Airbag/pretensioner safety: if you’ll be working near airbags or seat-belt pretensioners, wait a further 3 minutes after disconnecting.

Reconnecting & Restoring

  1. Reconnect positive (+) first, then negative (−) last; tighten both and refit the cover.
  2. Reset the date and time and re-enter any radio presets/personal settings.
  3. A few one-off warning lights may show after the first start — they normally clear once the car relearns idle on a short drive. (A workshop would also clear any stored codes.)

The Juke doesn’t need the new battery coded, and there’s no separate window re-initialise step listed for it.

Frequently Asked Questions

Which terminal first on the Juke?

Always the negative (−) first, and reconnect it last, to avoid shorting against the body.

Why such a long wait before disconnecting?

Nissan wants the control units to finish writing and sleep before power is cut — about 12 minutes — which avoids glitches when the battery comes off.

Will I lose my radio?

The Juke’s infotainment isn’t code-locked, so it comes back on its own — you’ll just reset the clock.

Does it need the battery registering?

No — the Juke doesn’t require battery coding. Fit it, reset the clock and you’re done.

If a warning light stays on afterwards, look it up on autodtcs.com. To clear the service reminder, see our Juke service reset guide.
