5.6 STORAGE INFORMATION
In normal use, the battery utilizes the aircraft power to maintain the proper charge voltage and
sustain the battery cells at peak capacity. Although the cells have an extremely low relative self-
discharge rate, all batteries will slowly self-discharge if left unused for long periods. In addition,
self-discharge rates are directly related to the storage temperature. Higher storage temperatures
will result in faster self-discharge rates.
Rechargeable lithium-ion batteries must be stored in a dry, well-ventilated area. They must not be
kept in the same area as highly flammable materials. The unit can be stored in the same area as
other battery chemistries. The battery does not emit or absorb any gas during storage,
transportation, or during normal operating conditions.
NOTE: The unit is shipped with approximately 30% state-of-charge (SOC). Upon
receipt the battery shall be fully charged using the procedures listed in this manual
(prior to storage and again prior to installation/use).
STORED BATTERIES MUST BE FULLY RECHARGED AT A
MINIMUM EVERY 6 MONTHS.
SHELF-LIFE: Batteries stored for an extended period of time must be occasionally recharged.
Follow the procedure set forth in Section 5.4.2 for charging. If the storage time is unknown, a
battery should be recharged prior to reaching 10% state of charge according to the indicator on the
front of the battery.
If a battery is allowed to self-discharge after it has been depleted (i.e if it is not
recharged within 7 days), the cells can be damaged. If the battery becomes over-
discharged due to this condition, it will protect itself by preventing subsequent
charging. The battery must then be returned to the factory for assessment.
STORAGE TEMPERATURE: Exposure to temperatures above 30°C (86°F) for sustained periods
of time are possible, but may increase the self-discharge rate or result in some permanent loss of
capacity. Storage temperatures above 50ºC (122°F) are to be avoided.
