I was looking for my APC UPS a new battery for replacement and attempts this. The delivery was fast and the battery was well packaged. The battery itself makes a good impression when you hold it in your hands and the contacts as well as the weld seam are flawlessly. After connecting the battery, I realized that this was already fully charged and my UPS was able to go into operation correctly immediately. During installation I have had the positive short to the housing resulting in a short circuit - this usually happens not if it is provided, however, the positive thing is that I was able to notice that the battery me this human mishap not resented - it works flawlessly , I would recommend this product without restrictions! Many Thanks.
