How to know the UPS is actually working?

<< < (2/2)

Here is another point:  most UPS will detect when a battery is replaced.  It is true that batteries are fully charged when they leave the factory, but they will lose charge just sitting on the shelf, believe it or not.  It may be going through an initialization by discharging the battery completely, then recharging the battery fully.  This is referred to conditioning to provide a fully charged system.  Modern rechargeable batteries develop a "memory" which limits the amount of deliverable power it can provide.  It is always best to completely discharge a battery before recharging it.  This will greatly increase the life of any battery ... cell phones, cordless razors ... anything that is rechargeable.  My UPS has a "conditioning mode" that does this automatically upon selection.  I'm not saying that there isn't something wrong with the UPS, but it is more likely that with many power interruptions in your area your older UPS may not have a conditioning mode.  It will only partially discharge before power is back, then charge back up from that point.  The next time it has a power interruption, the battery will not be able to give you a full discharge cycle.

Hi, Is it not funny that a device is there with use, but without any help manual about the process. Yesterday, i bought numeric ups, said to be good one, but there is no help manual of how to use it or what those beeps meant. apcups, when switch on, shows blinking yellow light to become green to show that it is working.
                             numeric on the other hand if switch on, creates a medium beep sound to become green.
                                       Normally users are advised to keep the power on the socket connecting the ups, but who knows whether it is working properly maintaining its conditioning .
                                              So, the electricity charges are increasing even on static conditon, when the ups is not used, but merely charging.
                                                      Normally mobile batteries show the battery position to recharge and it is normal that it is to be recharged. But there is no indication, whether the ups has received the maximum current it requires . Thus it keeps on charging whether the maximum it reached. It could be that a mechanism is there to cut the power supply once it reaches maximum, but the main power is on so the electricity consumption is going on. Is it correct, Shane
                                                              Should one charge it continuously, without break? there was no clear answer as to how many hours it should be charged.
                                                                   Does the battery back up is working when we are using the computer?. Is that enough if we power on the ups and power off the ups , including the main switch only on use? I do not find any articles on those trickier things. Even digital ups does not have any indicator other than the main switch.
