1. What is the FireLite ES200X Battery Replacement Calculation?

The FireLite ES200X battery replacement calculation determines the appropriate replacement battery capacity based on the original capacity and its current degradation state. This helps ensure proper backup power for fire alarm systems.

2. How Does the Calculator Work?

The calculator uses the replacement formula:

Where:

• \( \text{Original Ah} \) — The original amp-hour rating of the battery
• \( \text{Degradation Factor} \) — The remaining capacity as a decimal (0.8 = 80% remaining capacity)

Explanation: The equation accounts for battery capacity loss over time to determine the appropriate replacement capacity.

3. Importance of Battery Capacity Calculation

Details: Accurate battery replacement calculation is crucial for maintaining proper backup power duration in fire alarm systems, ensuring compliance with safety regulations.

4. Using the Calculator

Tips: Enter the original battery capacity in amp-hours and the current degradation factor (0-1). The degradation factor can be determined through battery testing or manufacturer specifications.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical degradation factor for replacement?
A: Most batteries are replaced when they reach 70-80% of original capacity, but consult manufacturer guidelines.

Q2: How often should battery capacity be tested?
A: NFPA 72 recommends testing standby batteries at least annually.

Q3: What affects battery degradation?
A: Temperature, charge cycles, age, and maintenance practices all affect battery degradation.

Q4: Should I round up the replacement capacity?
A: Yes, it's recommended to round up to the nearest standard battery size for safety margin.

Q5: Are there other factors to consider?
A: Yes, also consider load changes, environmental conditions, and any system modifications.
