d) Fast Charge ("FAST CHG")
When charging a lithium rechargeable battery, the charging current reduces continually due to
the charging method used, the fuller the rechargeable battery becomes (when the rechargeable
battery has reached its maximum charging current and the charger switches from continuous
current to continuous voltage charging). This will, of course, also extend the charging time.
Quick charging reaches a higher charging current. However, this reduces the capacity, because
the charge process is terminated earlier due to the safety cut-off in the charger.
This means, a LiPo battery, for example, cannot be fully charged using the fast charge function.
Only approx. 90% of the capacity achievable with the normal charge process is available.
Therefore, fast charging is only wise if the battery has to be used again as quickly as
possible.
The procedure when setting the charging current and voltage/cell number must be performed as
for the rechargeable battery programme "CHARGE"; see chapter 11. b).
e) Storing Rechargeable Batteries ("STORAGE")
This rechargeable battery programme can be used if you want to store the rechargeable battery
for an extended period. Depending on the rechargeable battery type set, the rechargeable bat-
tery is charged or discharged to a specific voltage.
Depending on the cell voltage, the battery is either charged or discharged. Of course,
with a multi-cell battery pack, this is only wise if a balancer connection is available and
connected to the charger.
At extended storage of a lithium rechargeable battery (e.g. when storing a flight bat -
tery over winter), the rechargeable battery should in any case be checked every 3
months and treated with the rechargeable battery programme "STORAGE" again to
prevent harmful deep discharge.
The procedure when setting the charging current and voltage/cell number must be performed as
for the rechargeable battery programme "CHARGE"; see chapter 11. b).
