How To Diagnose A Dead Battery In Under 60 Seconds
Three fast signs your battery is the culprit — and the one mistake that kills batteries early.
Most batteries last 4–6 years in UK conditions. The number-one killer is short journeys — your alternator never gets enough cycle time to fully recharge.
**Signs of a dying battery:**
- Slow crank on cold mornings
- Electrical glitches (dashboard flicker, intermittent locks)
- Swollen battery case
Our mobile units carry a load tester and can confirm in 60 seconds whether you need a jump or a replacement.
