Due to our knowledge of consumer devices, the three-year lifespan will certainly look shorter. There are cases of people who haven't changed the battery in their car in 10 years, and many others who can say that they have been on a smartphone for 4-5 years without having to replace their battery and it still works fine. However, when talking about replacing a UPS battery, then we should pay attention to the series other things.
Battery life
By their nature, batteries used in UPS should be replaced from time to time, and as we mentioned, manufacturers usually say this is three years (one of the first orders like APC (owned by Schneider)), from three to five years which seems more reasonable). However, the time when a UPS battery can stay in good condition varies depending on temperature, load voltage sent to, operating cycles, etc.
For this reason, manufacturers offer us a "medium" life cycle, or in other words, that the battery should be in good condition. It may be that they stay a little longer, or they may be longer. What is clear is that in order to extend battery life to the maximum we have to pay attention to a series of considerations that will help us to extend the battery life time at UPS.
Battery tips last longer
It is very important keep the UPS in a cool and dry place and more thin air. There is nothing to cover under the table where there is dust and no air flow. As a suitable temperature process, UPS should never exceed 25 ° C, since batteries are usually lead-acid and at elevated temperatures, their lifespan is reduced. As a guide, at all 8ºC the temperature is increased, the battery capacity is reduced by half.
For example, if a battery has a lifespan of 4 years, this is 25 ° C. If it stays at 33ºC, then its lifetime is 2 years, and if it has it at 4ºC, then it is only 1 year.
For this reason a little air is important, and this is not to say that we should put it under the air or have someone point it out. We just leave at least 5 inches of separation between the UPS and anything else (unless of course, the ground or above where we have it) for a little breeze.
Many UPS have self-management plans, but it is best not to do this process more than once a year because, in addition to being unimportant (not necessarily less, it is controversial.) Similarly, if you do not use UPS It is best to do a full billing cycle at least every six months to extend battery life.
Finally, the most obvious but probably not the most: do not overload the UPS. Ideally, the load should never exceed 80% of its capacity, that is, if for example we have a 400 watt UPS, do not connect equipment that uses more than 320 watts.
So how often do I change the battery?
The first thing you should know is that the parameter gives you the manufacturer, which it will be average life expectancy
Now, when the time comes when power goes off and the UPS lasts no more than a few minutes, less than it should be, then you will know that you will need to replace the battery in a short time. Also, pass self-diagnostic tests at least once a year, because if the battery is damaged, remember that are made of lead-acid and can be drawn and spend it down or wherever you can, and even create a eruption in extreme cases.
In the end, we should also pay attention to quality and the manufacturer, because with UPS over many things, it's cheaper and cheaper. As an individual, UPS of questionable origin ended up producing acid for over a year of use, and yet the APC Back-UPS 1400 UPS lasted five and a half years before the battery test had been restored.
