Picture this: 38°C summer. You’re in your 1.4L gasoline sedan, AC blasting, stuck in rush-hour traffic.
Your alternator is spinning at 680 RPM and producing less than 25A. Your battery is quietly dying.
The #1 Cause of Summer “No-Start” in Small Gasoline Engines
| Trigger | Damage |
|---|---|
| Idle RPM < 700 | Output drops 60% vs highway |
| AC + fans + lights | Load spikes to 55A |
| Battery net discharge | 1.1Ah lost per 15-min jam |
Field study (300 city cars, 2024): 71% of battery failures in July–August were idle-drain related, not heat alone.
