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 ba
ttery 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 AC supply has been disconnected and reconnected.
3.5 Estimating charge time
A lead-acid battery is about 80% charged at the beginning of the
absorption period.
The time
T
to 80% charged can be calculated as follows:
T = Ah / I
Where:
I
is the charge current (= charger output minus load current).
Ah
is the amount of Ah to be charged.
A full absorption period of up to 8 hours is needed to charge the
battery to 100%.
Example:
Charge time to 80% of a fully discharged 100Ah battery when
charged with a 10A
Blue Smart Charger: T = 100 / 10 = 10 hours
Charge time to 100%:
10 + 8 = 18 hours.
A Li-ion battery is more than 95% charged at the beginning of the
absorption period, and reaches 100% charge after approximately
30 minutes absorption charge.
