Confirm the current model specification and applicable test conditions before system approval. Charging, discharging and storage limits are separate requirements.

Use measured retention with the correct reference

The low-temperature table reports discharge performance at 0.5C. Keep the discharge cut-off and reference-temperature capacity with any comparison. Capacity retained after 772 or 548 observed cycles describes those tests; it is not a quoted total service life. Check the applicable charging limits before designing a cold-climate system.
