1. What is Battery Life Calculation?

Battery life calculation estimates how long a battery will last based on its capacity and the current drawn by the connected load. This helps in planning battery replacement schedules and system design.

2. How Does the Calculator Work?

The calculator uses the battery life equation:

Where:

• \( T_{year} \) — Battery life in years
• \( C \) — Battery capacity (Ah)
• \( I_o \) — Battery output current (A)

Explanation: The equation calculates how many years a battery will last by dividing its total capacity by the annual current consumption (daily current multiplied by 365 days).

3. Importance of Battery Life Estimation

Details: Accurate battery life estimation is crucial for system reliability, maintenance planning, and ensuring uninterrupted power supply in critical applications.

4. Using the Calculator

Tips: Enter battery capacity in Ah (Ampere-hours), output current in A (Amperes). All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What factors affect battery life?
A: Temperature, discharge rate, depth of discharge, and battery chemistry all significantly impact actual battery life.

Q2: Is this calculation accurate for all battery types?
A: This provides a theoretical estimate. Actual life may vary based on battery chemistry and operating conditions.

Q3: How does temperature affect battery life?
A: Higher temperatures generally reduce battery life, while lower temperatures reduce capacity but may extend overall cycle life.

Q4: Should I consider battery aging in calculations?
A: Yes, batteries lose capacity over time. For critical applications, include a safety margin in your calculations.

Q5: How accurate is this simple calculation?
A: This provides a basic estimate. For precise calculations, consider Peukert's law and other battery-specific factors.
