Important Considerations:

• Efficiency: This formula doesn't account for energy loss during conversion. Inverters, for example, have efficiency losses. You might need to reduce the calculated backup time by 10-20% to account for this, depending on the system's efficiency.
• Depth of Discharge (DoD): It's generally not recommended to fully discharge a battery. Deep discharges can damage the battery and shorten its lifespan. You may want to consider a lower DoD (e.g., 50%) in your calculation.
• Battery Age and Condition: Older or poorly maintained batteries will have a reduced capacity, resulting in shorter backup times.
• Load Variation: If the load is not constant (e.g., a fluctuating power draw from a computer), the calculated backup time will be an approximation.

Example:

A 12V, 100Ah battery powers a device consuming 100W. Backup time = (100Ah * 12V) / 100W = 12 hours. However, accounting for 15% efficiency loss, the actual backup time might be closer to 10.2 hours.

Simple Explanation:

Battery backup time is roughly calculated by multiplying the battery's Amp-hour (Ah) rating by the battery's voltage (V) and then dividing the result by the load's wattage (W).

Casual Reddit Style:

Dude, it's like this: (Battery Ah * Battery V) / Load W = Backup time (ish). But, seriously, gotta factor in efficiency losses and don't totally drain your battery, or you'll kill it. It's not an exact science.
