Battery Pack Runtime Calculator

Use our Lithium Ion Battery Pack Runtime Calculator to discover what battery configuration your application requires.

Our Standard Battery Pack Runtime Calculator provides a basic approximation for runtime. It does not account for the battery’s internal impedance, which varies with the load current.

Rose’s proprietary Advanced Lithium-Ion Battery Pack Runtime Calculator accounts for internal impedance and utilizes empirical cell cycling data to provide a more accurate runtime calculation.

To learn more, see this blog post – How to Calculate a Lithium-Ion Battery Pack's Capacity and Runtime.
