Query: QUALITY NOT AS GOOD AS OLDER UNITS

I have used APC UPS's for over 20 years. The batteries used to last 4-5 years before replacement was needed. Not any longer. The 3 SU 750's I have all had the batteries die at about the same time-2.5 years from purchase. I removed the label on these battery packs to discover they are made by some no name companies in China. Have you ever heard of "Vision " batteries?. What about a company called "LONG". APC is charging premium prices for these battery packs and sending low quality batteries. True, they give you the harness and recycle the batteries for free but we all know that is what we are paying for.
