Correction of the charging voltage depending on the ambient temperature
As the temperature rises, the electrochemical activity of the battery increases. When the temperature drops, the
electrochemical activity of the battery also drops. In case of an increase of temperature, the charging voltage should be
reduced to prevent overcharging of the battery. If the temperature drops, the charging voltage must be increased. In order
to maintain the optimal battery life in the event of large fluctuations in operating temperature, a power supply with a
charging voltage temperature compensation system should be used, which reduces the charging voltage with increasing
temperature. The temperature compensation coefficient for ZEUS batteries is
-
20 [mV / °C / cell] in buffer operation and 30
[mV / °C / cell] in cyclic operation at 25°C. The characteristics presented below show the relationship between temperature
and charging voltage:
Operating temperature
The location of battery is very important to the life and capacity of the battery. The nominal operating temperature of
maintenance
-
free batteries is 20°C. Operation at temperatures above 20°C shortens the battery life. Any increase in
temperature 8 to 10°C above the nominal value reduces the battery life by half. For example, the service life of a battery
operated at 30°C will be reduced by half.
General storage conditions
The battery should be stored in a dry, cool and clean place with low humidity. The room temperature should be between 15
and 40°C.
After long
-
term storage, the battery capacity may be less than recommended. In order to obtain the capacity recommended
by the manufacturer, the battery should be subjected to several charge / discharge cycles (usually two cycles).
In order to ensure proper operation after storage, it is recommended to periodically charge the batteries at the following
intervals:
Installation
Install the battery in a clean and dry room. Under normal operating conditions, the battery does not emit any gases, so it
can work indoors with other electrical devices.
