D) Fast Charge ("Fast Chg"); E) Storing Batteries ("Storage") - VOLTCRAFT V-CHARGE 300 TOUCH Handbuch

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 recharge-
able battery has reached its maximum charging current and the charger switches from continu-
ous current to continuous voltage charging). This will, of course, also extend the charging time.
At quick charging, the continuous voltage charging method uses 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 func-
tion. 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 10. b).

e) Storing batteries ("STORAGE")

This rechargeable battery programme can be used if you want to store the rechargeable bat-
tery for an extended period. Depending on the rechargeable battery type set, the rechargeable
battery 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 battery
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 10. b).
