Backend Formula for the Lead-Acid Battery Runtime Calculator

The core formula revolves around the relationship: Runtime (hours) = Capacity (Ah) × Efficiency (%) / Load Current (A). This equation highlights the interplay between battery capacity, load, and efficiency. For example, a 100Ah battery at 90% efficiency with a 10A load yields a runtime of 9 hours.

Alternative approaches might factor in temperature effects or age-related degradation, but this formula provides a robust baseline for most practical applications.

Step-by-Step Calculation Guide for the Lead-Acid Battery Runtime Calculator

Consider a 120Ah battery operating at 85% efficiency with a 12A load:

1. Identify Capacity: The battery has a capacity of 120Ah.
2. Calculate Effective Capacity: Multiply by efficiency: 120Ah × 0.85 = 102Ah.
3. Determine Runtime: Divide effective capacity by load current: 102Ah ÷ 12A = 8.5 hours.

Common errors include miscalculating efficiency or omitting it altogether. Always verify these inputs to ensure precise results.

Glossary of Terms Related to Lead-Acid Battery Runtime

Capacity (Ah):

The total amount of energy a battery can store, measured in amp-hours. For example, a 100Ah battery can theoretically provide 10A for 10 hours.

Efficiency (%):

The percentage of stored energy that can be effectively used. For instance, a battery at 85% efficiency loses 15% of its energy during conversion.

Load Current (A):

The rate at which current is drawn from the battery, measured in amperes. A higher load current reduces battery runtime.

Runtime (hours):

The estimated duration a battery can power a load before being depleted. Calculated using battery capacity, efficiency, and load current.

Discharge Rate:

The speed at which a battery is drained of its energy. Faster discharge rates can decrease overall efficiency.
