Five things that shorten the life of your UPS battery

One of the more common questions we get asked is how long a UPS battery will last. The ballpark, general answer is 3 to 5 years; however that answer is generally, well… general. And that’s because the life of your battery depends on a whole host of factors. 

Those factors are what we’re going to discuss today. Here are some of the things that can shorten the lifespan of your UPS battery. Let’s jump right in. 

Ambient temperature

Every UPS battery has a thing called ‘rated capacity’ which is basically the capacity of the battery to operate in perfect conditions. Ideal temperature for a UPS battery is right around 77 degrees. If the battery is in higher temperatures than that, the lifespan of that battery will be shorter. Ambient temperature isn’t usually a problem in most server-settings; but in Industrial facilities and in unprotected conditions – it most always is. 

The number of discharges

If you’re noticing that your UPS battery doesn’t last as long as it used to; that’s likely due to the number of or the length of – the battery discharges. The more charges that happen, the harder it becomes for batteries to deliver power. The more discharges – the shorter the lifespan. 


This one’s pretty simple and obvious but age is significant. Batteries convert chemical energy into electrical energy. Even when your battery is being charged, the chemicals inside the battery will deplete, which will cause the battery to dish out less power and for shorter periods of time. So, no matter how well you take care of your battery there will come a time where it has to be replaced. 

Load size

If your battery can’t handle the load of the equipment that it’s helping to support, the life expectancy will be significantly shortened. This usually isn’t a problem so long as you have professionals who will make sure you have an appropriate battery for your setup; but it can happen when people take it on themselves to seek out a replacement battery on their own. Just call the pros and leave it to them!

Poor maintenance

No matter what, you should always get your server room properly maintained because without it, you can shorten the life expectancy of everything inside it – UPS battery included. Even when things say ‘maintenance free’ that’s not necessarily the case as these systems still need to be inspected for corrosion, buildup and leaks. Things like loose connections can also cause issues. Without maintenance, your batteries will have a shorter life.
