Формула
Charge time = (Capacity / Current) × efficiency factor
Водич чекор-по-чекор
- 1Enter battery capacity in mAh or Wh
- 2Enter charging current in mA or A
- 3Account for efficiency (typically 85-95%)
Worked Examples
Влез
Capacity: 3000 mAh, Current: 500 mA
Резултат
Time ≈ 6.3 hours
(3000/500) × 1.05 efficiency
Common Mistakes to Avoid
- ✕Ignoring charging curve slowdown
- ✕Using rated capacity vs actual capacity
