So berechnen Sie Battery Life
learn.whatIsHeading
Calculates battery runtime based on capacity, discharge rate, and device power consumption. Determines whether battery suits application.
Formel
Runtime = capacity ÷ consumption
Schritt-für-Schritt-Anleitung
- 1Battery capacity in mAh or Wh
- 2Device power consumption in mA or watts
- 3Runtime = capacity ÷ consumption
- 4Account for temperature and age effects (10-20% penalty)
- 5Adjust for self-discharge over time
Gelöste Beispiele
Eingabe
2000mAh, 500mA draw
Ergebnis
4 hours
Häufige Fehler vermeiden
- ✕Using rated capacity without accounting for usable capacity
- ✕Ignoring temperature effects on performance
Häufig gestellte Fragen
Why does battery life differ from rated?
Temperature, discharge rate, load profile, battery age, and self-discharge all reduce actual runtime.
How do I extend battery life?
Reduce power consumption, optimize discharge rate, manage temperature, use lower drain modes.
