Disconnecting the 12 V battery on a Suzuki SX4 S-Cross Mk2 (AK, 2022–present) is a simple engine-bay job — but the 1.4 Boosterjet mild-hybrid version carries a separate 48 V battery you must not touch. Read the safety note before you start.
Know Which Battery Is Which
- The main 12 V starter battery is in the engine bay — this is the one this guide covers.
- The 1.4 Boosterjet (K14D) is a 48 V mild hybrid with a 48 V lithium battery under the front passenger seat. Leave that to a Suzuki specialist — never disconnect or remove it yourself.
Disconnecting the 12 V Battery
- Turn the ignition off and wait 3 minutes before touching the terminals. Wear gloves.
- Disconnect the earth (negative, −) cable first and tuck it clear.
- If removing the battery, disconnect the positive (+) next, then the clamp.
Do not disturb the 48 V lithium battery under the passenger seat on mild-hybrid cars — that’s a workshop job.
Reconnecting & Re-teaching
- Reconnect positive (+) first, then the earth (−) last.
- Reset the clock and radio presets.
- Re-initialise the power windows — one-touch drops out after a power cut; see our window guide.
