Battery charge time estimates how long a battery takes to fully charge given current, capacity, and efficiency losses. Essential for managing devices and planning activities.
Fórmula
Charge time = (Capacity / Current) × efficiency factor
Guia passo a passo
- 1Enter battery capacity in mAh or Wh
- 2Enter charging current in mA or A
- 3Account for efficiency (typically 85-95%)
Exemplos resolvidos
Entrada
Capacity: 3000 mAh, Current: 500 mA
Resultado
Time ≈ 6.3 hours
(3000/500) × 1.05 efficiency
Erros comuns a evitar
- ✕Ignoring charging curve slowdown
- ✕Using rated capacity vs actual capacity
