6. STORAGE
Keeps the battery at reduced constant voltage to limit
gassing and corrosion of the positive plates.
Slow self discharge is prevented by an automatic weekly
refresh of the battery with a short absorption charge.
7. READY
The battery is fully charged when the FLOAT or STORAGE
LED is on.
3.2 Lithium-ion (LiFePO₄) batteries
When charging a Lithium-ion battery, the Blue Power Charger
uses a specific charging algorithm for Lithium-ion batteries, to
ensure optimum performance. Select LI-ION with the mode
button.
3.3 When a load is connected to the battery
A load can be applied to the battery while charging, as long as
the current draw is much lower than the rated output of the
battery charger.
Reconditioning is not possible when a load is connected to the
battery.
Remarks:
a) Disconnect all loads before attempting to recharge a very
weak or fully discharged lead-acid battery. Loads may be
reconnected once the bulk phase has started.
b) Disconnect all loads before attempting to recharge a Li-ion
battery when the under voltage protection (UVP) of the
Li˗ion battery has tripped. Loads may be reconnected once
the bulk phase has started.
3.4 Triggering a new charge cycle
A new charge cycle will start when:
a) The charger has reached float or storage, and, due to a
load, current increases up to maximum current during more
than four seconds.
b) The MODE button is pressed during charging.
c) The AC supply has been disconnected and reconnected.
