The 12V battery on the Suzuki Alto (2009-2014) sits in the engine bay. Disconnect it in the right order to protect the electronics.
Disconnect
- Switch everything off and remove the key.
- Undo and remove the negative (−) terminal first; tuck the cable clear.
- Remove the positive (+) terminal.
- If lifting the battery out, undo the hold-down clamp and keep it upright.
Reconnect
- Fit the battery and clamp (if removed).
- Connect positive (+) first, then negative (−); tighten both.
Afterwards the clock resets; let the engine idle for a minute to settle. The Alto uses a small 35 Ah battery – match the original’s capacity and terminal layout.
Frequently asked questions
Which terminal first? Negative off first; positive on first.
