2.3.4
Temperature Range for
Charging
If the temperature is below 10
8
C, the
charger will automatically reduce the
rate of charge to avoid cell damage;
the STATUS indicator will show red,
the CHARGING indicator will
illuminate and charging will continue
at the lower rate. Normal fast charging
will automatically resume when the
pack temperature exceeds 10
8
C.
When using the discharge before
charge mode below 10
8
C, the fast
charging mode is not entered until the
pack temperature exceeds 10
8
C.
The charger has a safety cut-out,
which will operate if the pack
temperature rises above 45
8
C. In this
case the charger will not charge and
the STATUS indicator will show red. No
indicators or functions operate in this
state. The pack should be removed
and the charger power supply
momentarily disconnected to reset it.
2.3.5
Re-calibrating the ‘In-pack
Intelligence’
In normal use the ‘in-pack intelligence’
automatically re-calibrates the full
capacity of the pack whenever it
receives a full discharge.
If the battery pack is often used for
short periods and never fully
discharged the accuracy of the battery
status display in the camera will
reduce.
If it is suspected that there is any
inaccuracy in the bargraph display, re-
calibrate the pack by using the
discharge before charge function as
described in section 2.2.3.
It is recommended that this procedure
is carried out on each pack at least
once per month, to re-calibrate the
pack electronics.
Note:
A reduced charge capacity may
have arisen as a consequence of
ageing or damage within the pack.
