UPS - single points of failure

[markw at mohawksoft.com]

I read this post and it made me think. I am a big fan of both Triplite and
APC, having no problems with the units I have had for many years. Old and
new work perfectly. I also did not see in this message what the exact
failure was.

Most all UPS systems fail for one reason: lack of maintenence. The
standard gel type lead acid battery in these units needs to be replaced
every 2 or 3 years based on usage and room temperature. Most of these
units have a servicable battery and a maintnence schedule, but users never
do it,

The real culprit is battery technology, and lead acid specifically.
Everytime you drain a battery, it loses life. Lead acid batteries lose
life on a UPS as well. Over time they deteriorate, sometimes heating up
and spilling everywhere.

So, people look at your UPS systems, if they are more than three years
old, buy new batteries.

Also, you hardware hackers out there, there is no reason why your wimpy
little UPS system has to only provide 15 minutes of battery backup, you
can easily increase the capacity simply by getting batteries with a higher
amp/hour rating.
