Long-Term Storage
Long-Term Storage sets the IMPRES 2 or IMPRES battery to a State of Charge (SoC) suitable when storing
the battery for a long period of time.
The preferred SoC for storage is significantly less than fully charged, such as 50 %. Long-Term Storage at
75 % Rated Capacity is available for scenarios requiring the stored battery to be at a higher SoC such as
minimizing full-charge time if the battery must be quickly fielded or enabling storage for a longer period of
time.
Some IMPRES 2 or IMPRES batteries may be fully discharged before charging to the Long-Term Storage
selection. Such batteries are IMPRES 2 or IMPRES batteries that were never calibrated or require a new
calibration.
Long-Term Storage applies only to IMPRES 2 or IMPRES batteries. Other batteries (such as Unknown or
Motorola Solutions non-IMPRES or Clamshell batteries) are faulted.

IMPRES 2 Batteries with Sleep Mode
Some IMPRES 2 batteries are equipped with a Sleep mode. Sleep mode is used to extend the time until the
next battery charge. Upon completion of Ship Lithium or Long-Term Storage charging, the charger puts these
batteries to sleep.
Placing a sleeping IMPRES 2 battery into any charger will wake it up. If the battery is prepared for Lithium
Shipment, placing it into a charger set to Ship Lithium will put the battery back to sleep. If the battery is
prepared for Long-Term Storage, placing it into a charger set for Long-Term Storage will put the battery back
to sleep.

Calibration Menu
The calibration setup selection enables or disables the discharge phase of calibration or reconditioning.
Figure 7: Calibration Menu
The discharge phase precedes the full charge required for successful calibration or reconditioning. This
feature is useful when the charger is deployed to a location requiring the battery to be at a charged
