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 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 Power Charger: T = 100 / 10 = 10 hours
