Operating and Storage Temperatures
Ranges of temperature applicable to operation of the HR03 cells are:
Charge @ 0.1C: 32擄F to 122擄F (0擄C to 50擄C)
Discharge @ 0.1C: -4擄F to 122擄F (-20擄C to 50擄C)
Storage: -40擄F to 122擄F (-40擄C to 50擄C) (6 Months Max.)
-4擄F to 95擄F (-20擄C to 35擄C) (2 Years Max.)
Operating at extreme temperature will significantly effect service and cycle life.
