learn.whatIsHeading

Calculates battery runtime based on capacity, discharge rate, and device power consumption. Determines whether battery suits application.

Formule

Runtime = capacity ÷ consumption

Stapsgewijze handleiding

  1. 1Battery capacity in mAh or Wh
  2. 2Device power consumption in mA or watts
  3. 3Runtime = capacity ÷ consumption
  4. 4Account for temperature and age effects (10-20% penalty)
  5. 5Adjust for self-discharge over time

Uitgewerkte voorbeelden

Invoer
2000mAh, 500mA draw
Resultaat
4 hours

Veelgemaakte fouten om te vermijden

  • Using rated capacity without accounting for usable capacity
  • Ignoring temperature effects on performance

Veelgestelde vragen

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.
