You wake up to a strange sound coming from your home office. It’s an annoying beep that happens every four seconds. Quickly you review in your mind if you replaced the Smoke Alarm batteries lately or if you never plugged back your cordless phone.
So you finally get up, and search for the culprit. Not the phone. Not the smoke alarm. You get down on the floor and finally discover that the sound is coming from your UPS; your battery backup which is protecting your home computer.
But you just bought this at a deal from Home Depot less than a year ago? Yes it was an open box unit, but it hasn’t given any problems until now. You wonder if you can find another good deal on another one.
Just because your UPS is beeping doesn’t necessarily mean you need a new one. It may just mean you need a replacement battery (far cheaper than a new UPS).
How can you tell you need a new battery?
Well, first, get a flashlight. Some labels next to the beeping light/s are hard to read.
Most small UPS units have a battery light that when it is lit with a red light means it’s time to get a new battery. Often this light is on the top or front of the unit, though sometimes it is on the back where the power cord is attached.
So I have to replace the battery? Now what?
There are a couple of things that you may do.
First, turn off all the devices that are plugged into the battery backup and turn the UPS off. Then take the entire unit to a battery store like Battery Depot or Battery Express (just look up Batteries and your city name under Google and you’ll be able to find the right store). The store employees should be able to not only match the new battery to the type and model of UPS but most of them will install it for free.
Second, if you’re feeling adventurous, you could remove the battery itself and take it to the battery store to get a replacement and then install the new one yourself.
Now there are so many UPS makes and models and each is slightly different in how to replace the battery (though they all have some commonalities). The best bet to get it right the first time is to search YouTube using the make and model of your UPS and adding “Replacing the Battery” at the end. There is probably a video showing just how to do it.
If you search for “APC 350 Replacing the Battery” you may get a video like this:
This video does a great job in showing how to replace the battery in an APC BackUPS ES 350. It is actually very similar to replacing batteries in most UPS’s.
Either way, when the battery is replaced, that annoying beeping sound will be out of your life once again (unless you actually did forget to replace the batteries in your smoke alarm or left your phone off the charging base too long!).
