When i failed the battery of the ups, i wanted to check the veracity of different videos that you can restore the battery and thus to repair the ups.. A: ups backup batteries should be serviced semi-annually and replaced every 3-5 years, depending on the ups battery testing results and environment. the hotter the room the quicker the ups batteries will fail and require replacement.. Repair and improve broken apc ups rs-500 not charging. one day my ups stopped to charge the battery. after first look inside i found two resistors that were apparently broken (r150 and r151)..
Modern pcs have 350-500 watt power supplies ( more for extreme rigs ), so you need at least a 350-500 va ups, especially if you want to also have the monitor plugged in ( to a battery backed outlet ).. Never throw away your ups first, maybe your ups is not dead yet. you might repair it within a few minute. many computer shops will ask you to buy a new one ups rather than change the battery, because they want to push their sales only.. Ups battery replacements are easy enough to do yourself. the hardest part: finding the battery. in this post, we’ll show you how to crack open a ups case and get a good deal on a replacement ups.
