Absorption phase
In this phase the charge voltage must be maintained at UAbsorption to fully charge the
battery. If the charger currents drop below 5% (Imin) of the 1C current the absorption phase
can be maintained for t2 minutes, see Table 16.

Float phase
In this phase the charge voltage is set to UFloat. If the battery voltage drops below UReturn
for longer than t4 seconds than the charging process has to be repeated.
