Battery Replacement for Single Phase and 3 phase

[Anonymous user]

Hi

Is there any document from KB or white paper that state the best practice when to replace a battery ( i.e. every 2 yrs or 3 yrs ) for Single phase and 3 phase ups?

Hi Hanz,

I am unable to find a document on this, mostly because this is a true matter of environment.  Personally, I have seen batteries last anywhere from 1-10 years all depending on the owner and envrionment.  Factors that effect battery lifespan include:

-Temperature of room

-Number of discharges

-Quality of input power

-Time in storage prior to installation

-Type of unit

For single phase, we give a rough estimate of 3-5 years to answer your question once we explain the above contributing factors.

Hi Jordan and Hanz,

Here are a few white papers/application notes that could apply, or at least pieces of them may:

Thanks for the info guys.

Im not sure if this is true or not as a best practice, as per IT guy every 2 years they replace the battery of the UPS even the battery is still in good condition ( Single phase or 3 phase UPS ) bcoz they can't afford a sudden downtime due to battery faulty/issue.
