46145 Prussian-Blue Sodium-Ion Cell — 3.12V 13Ah

The RPA 46145 is a cylindrical Prussian-blue sodium-ion cell for engineers developing starter packs. Its catalogue provides separate continuous-discharge, pulse-power and cycling results so a pack can be evaluated against an actual starting duty.

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

Evaluate pulse performance at the required temperature

Compare the pulse duration, temperature, state of charge and voltage limits with the intended starter pack. The published 10-second pulse table is not a complete vehicle starting qualification. Confirm the charging-temperature range and pack protection design separately.
