9.8.1

General

Reaching the cells in test capacity less than 80% of its rated capacity, the battery manufacturer rec-
ommends as measure reconditioning.
The reconditioning may be performed manually by the programs DISCHARGE, DEEP DISCHARGE
with individual resistors and CHARGE / INITIAL COMMISSIONING. The details refer to the Mainte-
nance Manuals of the battery manufacturer. An alternative to using individual resistors provides
Nortec Electronics comfortable Zero-volt adapter as accessories.
The UL60 has an automatic program for reconditioning, for this the use of automatic Zellmeßadapters
is required. Please note that during auto reconditioning with UL60, the device can not be used else-
where.
In the following, the automatic reconditioning with UL60 will now be described.

 Rated capacity
Waiting after program step "Deep Discharge"? (see step 4)

Step 1:
Discharging with C until a voltage of 1 V for each cell is reached.

Step 2:
Afterwards discharging with C
Step 3:
Deep discharging with device integrated 1 Ohm resistors over each cell for 24 hours.
Step 4:
D
epending on settings the device might wait after executing Step 4. This will prevent, that e.g. in the
night the request to control the electrolyte level might occur.
8 hours charging with 0.2×C
15 minutes before the end of the charging you are asked to control the electrolyte level
Step 5:
Wait for 60 minutes.
