Battery replacement turned ON and flashing. Result: Battery: can be used, but no really good.īattery Bad: APC software indicates battery not detected. After 3 minutes, battery remaining 50% and only 10 minutes of estimated run time. The estimated running time with battery (initial) was 30 minutes. Result: Battery good.īattery "acceptable condition": charge in battery drop from 100% to 70% in 3 seconds. After 15 minutes I still have 71% battery. I then disconnected the APC from AC and check Powerchute Personal Edition.īattery good: charge in battery was draining. I charged the battery until reached 100%. I installed the battery to be tested and install APC software in my computer. I get an APC UPS (550VA) and connected 2 laptops. As Da_Schmoo said, APC and TrippLite both have that feature in their software, as does Cyberpower.I do it. In the event you were testing batteries in a UPS that wasn't all that old then i would also recommend using the battery test feature in the software from whichever company you have a UPS from. Its easy to convince management when you say "if the power goes out for 30 seconds all of our servers and the entire network *might* just shut down. TLDR If your batteries are 5 years old, get new ones. I had batteries that were missing part of the casing that still showed 12v. There isnt any way to really tell if the battery might still have some life left in it. Usually a test can be done on the batteries, via a web panel, or manually (dont do this on production servers) where it will simulate a power failure, and it recalibrates itself based on the length of time the batteries put out a usable voltage. I would recommend following your manufacturers suggestions, but lead acid storage batteries don't last forever. These batteries were upwards of 10 years old and were starting to do things like warp and melt and explode. I had 8 ups units that I inherited when I started here, and they hadnt been replaced or had a draw down test done on them. As Da_Schmoo said, APC and TrippLite both have that feature in their software, as does Cyberpower.Īll of the suggested battery life lengths I've seen are 3-5 years. In that case, you'll have to judge the battery health by seeing how quickly it takes the batteries to drain (easier if your UPS units have an LCD screen that displays estimated runtime). If they're just pretty bad it might run the radio for a few minutes. If the batteries are really bad, the UPS will probably fail outright and power off. With that plugged in, unplug the UPS from the wall. Doesn't need to be all that big, even something like a portable stereo. Power everything down that's connected to the UPS and instead of booting one PC/server to a USB stick/CD just plug something else into the UPS. If your batteries are at a point where you feel there's a good chance they will fail if you test them then I would second what LarryG said with a small change. This can cause batteries to heat up, deform, etc. As more of the plates are covered, they can no longer hold a charge. As they get old, they sulfate which means sulfur crystals build up on the plates inside of them. Lead-acid batteries, even when in use, generally have a lifespan of about 3-5 years. I'm mostly going to be echoing the others here because they're spot on. Do you use a battery tester or any other device? How I can be sure the battery I removed is really bad and need replacement?.How I can "test" if the batteries are good or need replacement if the battery replacement led or indicator in the UPS don't report any issue?.Do you change the batteries after certain amount of time or just wait for the "replace battery led to lit"?.We don't see any battery alert indication on the UPS.ĭo we need to replace the batteries only on the UPS who drop the load? Or we need to replace the batteries in all the UPS devices? We had some power glitches this week and notice a couple of UPS drop the load (PC and Monitors powered off). UPSs has been running with the same battery for the last 4-5 years and apparently still are in good condition but I'm wondering if due to time we need to replace all batteries. We have all servers and network gear protected with a High-End double conversion Online UPS.Ĭomputers (Dell Optiplex) are protected by APC or Tripplite UPS (750VA).
