(e)
Wait until the battery contactor opens.

(f)
On the lower ECAM display unit, ELEC page, make sure that the battery voltage is above 25V and the battery discharge current is equal to or lower than 1A.

1_ After some 12 seconds, the green line between the BAT 1 (2)
indication and the DC BAT busbar indication:
- goes out of view if the battery charge is correct,
- stays in view if a battery charge is necessary.
NOTE : The time for the battery to charge is approximately 20____
minutes.

NOTE : The power consumption of the HOT bus is normally lower
____ than 100mA.
(g)
Swap the BCL 1 and the BCL 2.

(h)
Start a charging cycle of the battery which was related to the failed BCL during the previous flight.

(i)
On the ELEC panel 35VU, push the related BAT 2 (1) pushbutton switch to start the charging cycle of the battery 2 (1).

(j)
Release the BAT 1 (2) pushbutton switch related to the BCL not in operation.
