It is not as if it is a mechanical device that "wears out". Is there any reason/justification from APC as to why it needs replacing or which bits fail? If you knew that you could do planned maintenance and replace those parts.

In answer to your question, it is the first time I have heard of any electronic device "wearing out".


My spelling is not bad. I am typing this on a Medigenic keyboard and I blame that for all my typos.
