D) Fast Charge („Fast Chg"); E) Storing Batteries („Storage") - VOLTCRAFT Ultimate 400 W Bedienungsanleitung

d) Fast Charge („FAST CHG")
When charging a Lithium battery, the charging current becomes increasingly lower the
fuller the battery due to the applied charge procedure for lithium batteries. This will, of
course, also extend the charging time.
A special charging procedure achieves a higher charging current in fast charging.
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 charge current and voltage/cell number must be
performed as for normal charging; see chapter 11. b).
e) Storing Batteries („STORAGE")
This function can be used to set the battery to a certain voltage level, which is regarded as
ideal for storage (LiPo = 3.7 V, LiIon = 3.6 V, LiFe = 3.3 V).
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.
The procedure when setting the current and voltage/cell number must be performed as for
normal charging; see chapter 11. b).
The set current is used for charging/discharging.
