Discharging Time Formula:
From: | To: |
Battery discharging time is the duration a battery can power a device before needing recharge. It's calculated by dividing the battery's capacity (in amp-hours) by the discharge current (in amps).
The calculator uses the discharge time formula:
Where:
Explanation: This simple calculation gives the theoretical maximum runtime of a battery under constant load.
Details: Knowing discharge time helps in battery selection, system design, and estimating runtime for electronic devices and power systems.
Tips: Enter battery capacity in Ah and discharge current in A. Both values must be positive numbers. The result shows estimated runtime in hours.
Q1: Is this calculation accurate for all battery types?
A: This provides theoretical maximum. Actual runtime may vary due to temperature, battery age, and discharge rate effects.
Q2: What's the difference between Ah and Wh?
A: Ah measures charge capacity, Wh measures energy capacity (Ah × Voltage). For same voltage systems, Ah is sufficient.
Q3: Does this account for battery voltage?
A: No, this assumes you're working within the same voltage system. For different voltages, consider power (Watts) instead.
Q4: Why might actual discharge time differ?
A: Factors like battery efficiency, temperature, discharge rate, and age affect real-world performance.
Q5: How does Peukert's effect relate to this?
A: At high discharge rates, battery capacity appears reduced (Peukert effect). This calculator assumes ideal conditions.
