A slide show that discuss 8 reasons for battery failure on single phase UPS (Uniterruptable Power Systems). Included in the slide show is pictures showing actual battery failures. This slide show demonstrates why single phase UPS units need maintenance performed on regular basis.

1. 8 Reasons
for a
Single Phase
UPS Battery
Failure

2. Walk into the Office
First thing you notice
is that burnt smell !

3. Have you checked your UPS batteries
in your single phase unit?

4. 8 Reasons
for a
Single Phase
UPS Battery
Failure
Loss of Run Time
Loss of Data
Component Failure
Will not take a
Charge
Batteries Dry Out
Bulging Cases
Batteries can not
be removed
may lead to replacing
UPS unit
Loose Connections
Causing Burnt
Terminals and Cables
Corroded Connections
Thermal Run Away
Excess heat
Fire
Leaking Batteries
damage equipment
messy to clean up
Typical Battery Life
4-5 years

Discharge Quickly

5. Loose Connection
causing
a burnt terminal
and cable

6. Loose Connections can lead to loss of
battery power when you need the
backup power during an utility outage.
Loose Connections can also lead to
unsafe conditions like a fire hazard
due to burning wires.

7. Corroded Terminal

8. Corroded Connections will lead to loss
of battery power.
If the battery connection can not make
good contact, then the battery can not
supply power when needed.

9. Bulging Case

10. Bulging Cases are cause by internal
faults in the battery due to age and
charge conditions.
Bulging cases can lead to loss of
battery power due to internal failure
of the battery.
A bulging cases can make if very
difficult to replace the battery and in
some case can require the
replacement of the whole UPS module.

11. Leaking
Battery Case

12. Typically, todays sealed batteries are
designed not to allow leaking if the
battery case becomes damaged.
Leaking battery cases can be caused
by old age and thermal runaway,
causing high heat.
If a battery starts to leak, then the
exposed acid has to be cleaned up and
nuetralized. The acid can lead to
damage of equipment.

13. Batteries are like a loaf of bread
Every time you use them,
you take a slice out of their
life!
Batteries get old and will not take a charge.
As batteries age they loose
run time.

14. Have regular maintenance
Performed on all single phase UPS units

15. + -
Don’t wait for battery failure!
Be Pro-Active
Change batteries every 4 years
on all Single Phase UPS units
