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. 
8.  REFRESH 
Slow self-discharge is prevented by an automatic weekly 
refresh of the battery with a short absorption charge. 
3.2 Lithium-ion (LiFePO
₄) batteries 
When charging a Lithium-ion battery, the Blue Smart 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.
