Operation With Nickel-Cadmium Batteries - Nortec UL10 Operation Manual

CHARGER / DISCAHRGER UL10

6.8.4 Operation with nickel-cadmium batteries

The information below relates to all types of batteries with the data input beginning with 2х and 3х.
Below is the list of the types in question:
•
Type 20: enclosed aircraft nickel-cadmium batteries
•
Type 21: enclosed nickel-cadmium batteries type VARTA
•
Type 30: enclosed nickel-cadmium batteries type SAFT
•
Type 31: enclosed nickel-cadmium batteries type NKBN
After the battery type is selected with the keys ← → and confirmed by hitting the key ENTER↵
the type of operation should be selected.
Any type of operation can be entered.
For example let us select the type 4: a enclosed aircraft nickel-cadmium battery. The LED reads:
Input of parameters
The number of cells
For the nickel-cadmium battery the number of batteries should be indicated and the battery voltage
is calculated by the device.
Note:
The nominal voltage of a nickel-cadmium battery is 1.2 V. The voltage 1.55 V is selected to charge it
fully. Unlike the lead acid batteries the nickel-cadmium batteries have sometimes a nonstandard
number of batteries.
The standard number of batteries
5 cells 5 х 1.2 V = battery 6 V
10 cells 10 х 1.2 V = battery 12 V
20 cells 20 х 1.2 V = battery 24 V
An example of the non-standard number
2 cells in portable lamps – 2.4 V
4 cells in portable lamps – 4.8 V
6 cells in piles of batteries for electric drills – 7.2 V
8 cells in piles of batteries for electric drills – 9.6 V
11 cells in piles of batteries for video recorders – 13.2 V
19 cells – special aircraft batteries
26 cells aircraft / guided flying missile Cormoran
Note:
It means that any input of the data and the number of nickel-cadmium batteries requires utmost
caution not to damage a battery.
Because of flexible data input the UL 10 is a perfect tool to charge and maintain batteries
with uncommon configurations of cells that masks the risk of their improper use!
