Discharging
1. Discharge the battery within an ambient temperature range of -10
°C to +45 °C
2. Discharge capacity drops at temperatures below -10 °C or above
+45 °C. Such decreases in discharge capacity can lead to
deterioration in battery performance.
3. Since over-discharging (deep discharge) damages the battery
characteristics do not leave the battery connected to the
instrument for long periods of time. Avoid shipping the
battery connected with the instrument.
4.
High-current
discharging can lead to heat generation and
decreased discharging efficiency.
Storage
1. Store battery in a dry location with low humidity, no corrosive
gases, and at a temperature range of -20 °C to +45 °C.
2. Storing the battery in a location where humidity is extremely high
or where temperatures fall below -10 °C or above +45 °C can lead
to rusting of metallic parts and battery leakage due to expansion or
contraction in parts composed of organic materials.
3. Long-term storage can accelerate battery self-discharging and
lead to the deactivation of reactants; locations where the
temperature ranges between +10 °C and +30 °C are suitable for
long-term storage.
4. When charging for the first time after long-term storage,
deactivation of reactants may lead to increased battery voltage
and decreased battery capacity. Restore such batteries to original
performance by repeating several cycles of charging and
discharging.
5. When storing batteries for more then one (1) year, charge at
least once a year to prevent leakage and deterioration in
performance due to self-discharging.
