41AQ557

The 41AQ557 is well-suited for low-temperature applications, thanks to its low internal impedance—this feature allows the cells to maintain good capacity output and stable discharge current even in cold environments.

The 41AQ557 can operate reliably at temperatures as low as -30°C. A key note: for low-temperature use cases, we strongly recommend conducting performance testing in your specific application scenario to ensure it meets your actual needs.
