Millions of people all over the world rely on UPS batteries.
UPS simply stands for Uninterruptible Power Supply. The function of these
batteries is to provide a backup cover system for many different types of
installations, in case of a power outage from the mains electric grid. One of
the key types of system is to cover for data systems and provide an emergency backup;
these systems are now part of everyday life, including major hospitals, banks, small
to large companies and even ships, in fact anything that stores its information
from a computer.
These UPS battery emergency backup systems are very important
and consequently have to be included in a very strict maintenance procedure. In
fact this is one of the main causes of down time and service call outs than any
other type of electrical component in the backup system.
It is therefore very important that the correct and best UPS
batteries are supplied when setting up a new system and the correct maintenance
procedures implemented, this is the first step. These systems are more important
than ever and good care is vigilance is essential; to ensure that the backup
system is in order and the data system is fully operative all the time. By performing regular preventative maintenance
the UPS system should perform as intended as a backup unit and help to protect
sensitive equipment (such as computer systems in banks and industry) and maintain up time.
One of the main considerations is the room temperature where
the UPS back up system is installed. Unknown to most people most type of
batteries are sensitive temperature fluctuations and it is important that a
stable ambient temperature is maintained. The recommended temperature of the backup
storage room should be the 77 degrees Fahrenheit mark and the room should also
be fitted with temperature sensors in order to keep the room at the correct
setting, any temperature rise will then set off warning alarms. The UPS batteries
are sensitive to temperature change; in fact a rise or fall of say 15 degrees
can alter the UPS batteries performance capacity of 10%.
Where possible individual UPS batteries should be checked
Regular checks should be carried out on individual
batteries, even though some of these UPS battery banks may contain many of
the XV31MF battery, (one bad apple could spoil the whole bunch) springs to mind. If you batteries
are not sealed then it is important to check the water levels in the UPS
battery, it is very likely though that your batteries will be the sealed type.
You should look out for any signs of corrosion on the
battery connecting wires on the battery terminals or posts, extra weight may be
imposed on the terminals by loose hanging connecting wires, this may cause the
battery to leak acid in the terminal area, this looks like a white powdery
substance that will be familiar to many car drivers on their discount car battery
terminals.

Another important thing that will be visible on inspection
is to look out for a warped or distorted battery casing, if you spot this then
the battery needs replacing as the battery was probably distorted through a
faulty cell or connection and has overheated, distorting the battery casing.
If all the batteries look clean and in good order then check
the voltage of each cell, this should read 2.5 volts per cell. If the voltage
of the UPS batteries has dropped below 2.2 volts them the battery should be put
on an equalizing charge. An equalizing charge can be better explained by this
useful link to Battery University... http://batteryuniversity.com/learn/article/equalizing_charge
If the battery is at the correct voltage after 100 hours
equalizing charge, then it can be used again on the system, if it does not then
the battery should be replaced. I would recommend that this should be recorded
in case of future problems with the same battery; also any issues that the
battery company may have corrected are better recorded for future use. Sometimes
the battery maintenance schedules are carried out by the battery company that
supplied the batteries.
Most companies or institutions that carry out battery maintenance
should keep spare and re-tested batteries in a separate area, this should
include some new batteries that are exactly the same the ones fitted in the backup
system. Good quality Lucas UPS batteries can be purchased from UK battery supplier

These batteries should also be kept away from a direct heat source such as a
radiator or any other type of heater and also away from direct sunlight; this
could also shorten a batteries life.
Also I have a few good housekeeping tips when handling batteries.
Never lift your batteries by the terminal or post as this could cause a leak in
this area, this includes lifting them out on their connecting cables and wires.
Always wear some protective clothing when handling any type of UPS or lead acid battery
They can and sometimes do explode, so eye protection in
the form of goggles are required.
When working with any battery you should use the correct insulated
tools in case you accidentally short out the terminals.
Do not clean them car batteries with solvents or any other
similar chemicals as these can cause the casing to melt, just use a clean damp
cloth.
