I got a desktop pc, i rather have this set up, then a laptop, or hand held device, in fact, i still have an old fashion "flip phone", heck, i buy repair kits for my garden hose. i like desktop pc's, as they can be opened up, and rebuilt or "souped up" with better hardware devices, and it's like another hobby for me. well back in April of 2016, i had bought a battery back up (UPS) for my pc, from Amazon. it is a Cyber Power, and was rated very high in reviews and dependability, and not just from the Amazon website. well now, the battery is kaput after 3 years. ok, no big deal, i searched for replacement batteries, and one website, Batteryrush, i am able to get a replacement for about $25.00..(this includes the price for shipping) clearly way cheaper than buying a whole new UPS, like back in the day when a replacement battery cost nearly as much as a new UPS. (i know, i had a Belkin UPS) way back in the day. so, if any of you have a desktop, and run with a UPS, have you had to replace the battery or the entire unit? i know i might be grasping at straws with this, as many more people have hand held devices than desktops. thanks in advance.
