How to activate the battery? UPS battery maintenance solution. In UPS power
supplies, maintenance-free sealed lead-acid batteries are widely used. Good
maintenance and upkeep can not only ensure the safety of power supply, but also
greatly extend the service life of UPS batteries. Perform routine maintenance on
the UPS battery, so as to extend the life of the UPS battery and reduce the
failure rate to the greatest extent.
How to activate the battery?
1. Unscrew the plastic cover of each compartment of the battery and check
the internal liquid level. If it is not enough, fill it up to the normal
level.
2. Use a multimeter to check the voltage of each grid to see if it is
basically close and whether there is reverse polarity. Whether the total voltage
is above 10.8 volts. If any individual grid is found to have low voltage or
reverse polarity, it must be supplemented or the polarity corrected
separately.
3. It is best to use a charger with adjustable voltage and current and a
voltage and current display meter. Connect the connection cable, turn on the
power, and observe the changes in voltage and current. If it reaches 14 volts
and there is still no charging current, continue to increase the voltage to 16
volts and wait.
4. As long as there is current, it means activation begins. Slowly wait for
the current to increase. When the current exceeds one-tenth of the capacity, for
example, when the current of a 24-hour battery exceeds 2.4 amps, reduce the
voltage and adjust the current to 2.4 amps. Wait until the voltage drops below
14 volts and there is still 2.4 amps of current. The activation is successful
and the charging stage is entered.
5. This kind of long-term UPS battery generally needs to be charged for
more than 14 hours, and the maximum charging voltage at the end of charging does
not exceed 14.9 volts.
UPS battery repair method
Pulse repair method:
A better way to eliminate sulfuration in batteries is to use the pulse
repair method. When repairing the battery, the instantaneous voltage of the
pulse is generally between 60V and 300V according to the functional needs of the
product. For example, the pulse voltage value of products used to extend the
battery life is not necessarily too large. Specially for battery repair products
The pulse voltage value can be too large. If the pulse voltage is high, the
battery repair time will be short. If the pulse voltage is low, the battery
repair time will be relatively long. Although the voltage at the pulse instant
is very high, the average voltage is not high, which does no harm to the human
body. It is very Safety.
Full charge and full discharge repair method:
The full charge and full discharge repair method is to fully charge the
battery and then completely discharge it to repair the battery. The full charge
and full discharge repair method mainly has a certain repair effect on slightly
damaged batteries. At the same time, this method can also effectively activate
the active substances deep in the battery and increase the battery capacity.
Hydration repair method:
The "water loss" of the battery can be repaired by replenishing water. The
purpose is to dilute the sulfuric acid with increased concentration to carry out
the electrolysis reaction normally. The method of replenishing water is
relatively simple. Just open the battery cover and you will see six round holes.
Inject a certain amount of distilled water into each hole and soak it for more
than 24 hours.
UPS battery maintenance solution
The UPS battery maintenance solution consists of three parts: battery pack
capacity monitoring, single UPS battery charge and discharge activation, and
battery-specific intelligent protection.
1. Battery pack capacity monitoring
The float voltage, current, charge and discharge voltage, and current of
the UPS battery can be monitored and recorded online. After recording the
discharge data, the performance of the battery pack can be judged, lagging cells
can be found, and the remaining capacity of each cell can be given.
2. Single battery charge and discharge activation
For the discovered backward single cells, charge and discharge to activate
the failed active material, reduce the internal resistance, compensate for the
voltage difference and supplement the remaining capacity, so as to avoid the
further deterioration of the backward single cell and affect other cells, that
is, perform early testing on the battery. Treatment and prevention, and timely
replacement of single batteries that cannot be compensated.
3. Special intelligent protection for batteries
Special intelligent protection for lead-acid batteries is a high-tech
technology that uses electronic pulse technology to perform automatic daily
maintenance on lead-acid batteries in use. The protector also has the function
of repairing lead-acid batteries that have failed due to shock, fatigue, or
overuse due to the saltation of lead sulfate on the plates. It cleverly uses the
energy of the battery itself to generate electronic pulses and feeds them back
to the battery. It uses electronic methods to effectively prevent the battery
from stable capacity output, improve the working efficiency of the battery,
fundamentally improve the working performance of the lead-acid battery, and
greatly extend the battery life. life, save money and energy, and also play a
positive role in environmental protection.
These three processes work together to solve the problem of the current
lack of necessary maintenance methods and tools for UPS batteries. They can not
only test the battery performance for you and find backward cells, but also help
you activate the backward batteries and provide early treatment to the
batteries, which is effective Prevent failures from occurring.
Monitoring the UPS charging system is an important part of maintaining the
UPS power system. Many users neglect the monitoring of the UPS charging system
due to the lack of necessary testing methods. If the UPS charging system is
broken, even if a new battery is replaced, its service life will be shortened.
will become shorter. The traditional method of judging UPS battery capacity is
the same as that of general batteries. The entire battery pack is separated from
the communication power supply system and put on a discharge meter. It is
discharged at a constant current rate of 10 hours, and then the battery pack is
discharged at a constant current rate that reaches the discharge termination
voltage first. The discharge time and current of the battery are used to
calculate its capacity.
