Most batteries last three to five years depending on climate, short journeys and electrical load. Stop–start systems demand stronger units.
Symptoms of a weak battery
- Engine turns over slowly or needs multiple attempts
- Dim headlights at idle
- Infotainment resets or warning messages
- Corrosion on terminals
MOT connection
The MOT includes checks that need a healthy electrical system — for example lamps, wipers and sometimes emissions equipment. A flat battery on the day delays testing; some faults trace to low voltage.
