Disconnecting the 12 V battery on your Abarth 124 Spider (2016–2020) — the Mazda MX-5-based roadster with the Fiat 1.4 MultiAir — for a new battery, winter storage, or work near the airbags is a straightforward job. The battery is in the engine compartment.
Find the Battery First
The 12 V battery sits in the engine compartment, towards the rear of the bay near the bulkhead. Note your radio security code and presets before you start.
Disconnecting Safely
- Switch everything off and remove the key.
- Disconnect the negative (−) terminal first, then the positive.
- Working near airbags or seat-belt pretensioners? Wait 10 minutes after disconnecting before such work.
Reconnecting and Re-initialising
Reconnect positive first, then negative, and wait about 5 minutes. The car then needs a few items relearned:
- Power windows — re-initialise one-touch (hold the switch fully up at the limit, then fully down).
- Remote control — may need re-synchronising (lock/unlock with the fob).
- Re-enter the clock and radio presets.
If Something Isn’t Right Afterwards
- Warning lights often clear after a short drive.
- A persistent light stores a code — look it up on autodtcs.com.
- Fit a like-for-like battery of the correct size and rating.
