Calculates time to fully charge a battery based on charger current and battery capacity. Helps optimize charging strategy.

Формула

Basic time = capacity ÷ charger current

Пошаговое руководство

  1. 1Battery capacity in mAh
  2. 2Charger current in mA
  3. 3Basic time = capacity ÷ charger current
  4. 4Account for taper charging (slows at 80-90% full)
  5. 5Typical 20-50% penalty for taper

Решённые примеры

Ввод
2000mAh, 500mA charger
Результат
4 hours

Распространённые ошибки

  • Assuming linear charge time (actual curve is non-linear)
  • Not accounting for charger efficiency (80-90% typical)

Часто задаваемые вопросы

Should I use fast charging?

Fast charging reduces battery lifespan by 10-20%; use only when needed; standard charging preserves battery.

What's optimal charging speed?

C/10 (capacity ÷ 10) is safest; C/2 acceptable; >1C causes heat and reduced lifespan.
