1. What is Battery Bank Capacity?

Battery bank capacity (measured in ampere-hours, Ah) determines how long a UPS system can support a given load. It's crucial for ensuring uninterrupted power during shipping or transit.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Shipping UPS Load — Power consumption of the equipment (watts)
• Time — Duration of required backup (hours)
• Voltage — System voltage (typically 12V, 24V, or 48V)

Explanation: The formula converts watt-hours to ampere-hours by accounting for the system voltage.

3. Importance of Proper Sizing

Details: Correct battery sizing ensures UPS systems can maintain power during transit without being oversized (which adds unnecessary weight and cost).

4. Using the Calculator

Tips: Enter the UPS load in watts, required backup time in hours, and system voltage in volts. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical voltage for shipping UPS systems?
A: Common voltages are 12V, 24V, or 48V depending on the system size and configuration.

Q2: Should I add a safety margin?
A: Yes, it's recommended to add 20-30% to the calculated capacity to account for battery aging and efficiency losses.

Q3: How does temperature affect capacity?
A: Battery capacity decreases in cold temperatures - you may need to increase capacity by 10-20% for cold environments.

Q4: What battery types are used for shipping UPS?
A: Common types include sealed lead-acid (SLA), lithium-ion, and absorbed glass mat (AGM) batteries.

Q5: How does depth of discharge affect calculations?
A: For longer battery life, don't discharge below 50% capacity - you may need to double the calculated Ah for lead-acid batteries.
