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?
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:
www.apc.com/whitepaper/?an=153 -Best Practices for Deploying Smart-UPS, Smart-UPS On-Line, and Symmetra
www.apc.com/whitepaper/?wp=30 - Battery Technology for Data Centers and Network Rooms: Lead-Acid Battery Options
www.apc.com/whitepaper/?wp=39 - Battery Technology for Data Centers and Network Rooms: VRLA Reliability and Safety
www.apc.com/whitepaper/?wp=36 - Data Center VRLA Battery End-of-Life Recycling Procedures
www.apc.com/whitepaper/?wp=34 - Battery Technology for Data Centers and Network Rooms: Ventilation of Lead-Acid Batteries
All white papers are here -> http://www.apc.com/prod_docs/results.cfm?DocType=White%20Paper&Query_Type=10
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.
