c) The internal resistance of all batteries
- should not be greater than the internal resistance of the new battery (shown
on the data sheet) increased by
30%
.
d) Battery charging current
- after a few days of loading it should decrease to
4 [mA]
per
1 [Ah]
of battery capacity or
lower but should be greater than zero.
e) Operating temperature in the battery space
- should be in the range between
15 -
25 [°C]
.
If the measured values exceed the permissible range, please contact the batteries supplier.
Additionally,
the battery capacity test
, involving
partial discharging
with rated current, should be performed
every 12
months
. This is especially important in the case when there were no longer voltage decays for several months and the
battery practically did not work. During the test, measure the discharge time, read or measure the value of discharge
current at regular intervals (every 15, 30 or 60 minutes, depending on the expected duration of the test) measure and
record the decreasing value of the battery voltage and the voltage of each cell. If the battery is fully operational, duration
of the test shall be in accordance with the discharge characteristics of the tested battery, while the battery voltage will
decrease evenly in all cells.
The time and duration of the battery capacity test should be properly selected to avoid the difficulties in the normal
operation resulting from the power loss during battery charging once the test is performed. The battery will reach its full
capacity after about 48 hours of charging.
5. Charging after purchase:
If the batteries are not installed within three months from the date of purchase, they should be charged with a voltage of
2.4 [V / C] for 24 hours. The batteries should be charged every three months; otherwise, your warranty may be void.
6. Cautions:
• Undercharged battery:
If the charging voltage is set incorrectly (too low or unmatched to the temperature), the entire battery is undercharged for
a long period of time. In case of power failure, the battery may not work properly due to the loss of capacity.
•
Overcharged battery:
Charging with higher voltage (which may be caused by not switching from accelerated or equalizing charging to buffer
charging or by a malfunction of the charger) can cause serious problems for the entire battery, such as water loss,
excessive gassing, a sharp temperature increase, shortened life span or deformation of the battery.
•
Improper temperature:
If the temperature of the battery space is too low, the battery's available capacity will decrease. In the case of high
temperature, water loss, shortening the life span or the battery deformation can occur.
•
Too low discharge voltage:
The depth of discharge of the batteries is a very important parameter. Discharging cells below acceptable levels can lead
to partial or complete loss of capacity or cause a significant decrease in charging efficiency, which in turn will lead to a
drastic reduction in the lifetime of the entire battery.
