UPS Backup Battery

Power failures do occur at times in our places of residents, businesses, and workplaces. This power failure can last for an extended period. And as we know, without electricity, all our work or pleasure will stop. Therefore, there is the need to have backup systems so that our work is protected from damage or data loss.

Also, backup systems help us minimize the financial loss caused by blackouts, low voltages, and other power supply problems.

Therefore, let us learn one excellent backup system known as an Uninterruptible power supply (UPS).


What is the UPS Backup Battery?

An Uninterruptible power supply (UPS) is also known as a battery backup, is an electronic device that provides emergency power when your regular power supply fails. UPS provides instant protection from input power interruptions by giving out the stored energy in batteries, robust capacitors, and flywheels.

Instant loss of power and power surges are two leading causes of damage to your devices. Thus, UPS protects hardware components of machines such as computers, data centers, telecommunication equipment, and all other electrical equipment. Power disruption can cause damage, fatalities, severe business disruption, or data loss.

UPS comes in different sizes, ranging from those meant to protect one computer without a monitor to those large units used to power entire data centers or buildings. Cheap power strips can protect your electrical devices but do not offer protection against drops in voltage, brownouts, blackouts, and other power supply problems.

Let us take, for instance; you are dealing with a project at home on your laptop with it plugged into an appropriate surge protection strip. You are busy with your work, and then suddenly, there is a power blackout. Although all the devices go off, your work won’t be interrupted since the laptop has a battery. This offers time to save your work then shut down your computer.

But for desktop computers, it is a different case. If you worked on your project on a desktop computer during the outage, then the system goes off when power is interrupted. This leads to loss of unsaved work and also gives your computer a lot of stress. UPS now plays its role here. It offers a window of time to save your work then shut the computer down in the right way.

You can also work for the entire period of interruption using the power stored in the UPS. Even in your absence, many UPS units come with software that enables them to detect a power outage and enables the computer to shut down automatically.

Main Types Of UPS Units

There are three main types of UPS units, namely:

A standby UPS unit – This type of battery backup charges its battery and then waits for the main power to be interrupted. When there is a power outage, the Standby UPS switches to the battery backup. It can support the device for a period of between 20-100 milliseconds, which is within the acceptable tolerance threshold.

A Line-Interactive UPS unit has the same design as a standby UPS unit, but a special transformer is included. This particular transformer makes this type of UPS better in dealing with brownouts and power surges. If you are residing in an area frequently affected by brownouts, this is the device to purchase.

An online UPS unit – this is the most expensive type of UPS. It completely separates the device attached to it from the wall power. There is never a single millisecond of power interruption with this backup system when there is power loss. The device is effectively an electronic firewall between your devices and the world, scrubbing and stabilizing all the electricity your devices are exposed to.

Can UPS Work Without the Battery?

UPS works mostly on batteries. Most UPS runs on batteries, and they cannot operate on dead or missing batteries. But in case you have the one that runs without batteries, then you will get the same voltage regulation and surge as you will be working with batteries.

Without batteries, the UPS will offer minimal protection, and even only the UPS’s surge side will work. You will not get line conditioning without a well-functioning battery. It is good to always have healthy batteries in your UPS for maximum protection of your hardware devices.

How do You Pick the Right UPS Backup Battery?

Picking the right battery for your home or device is always crucial. But these are the factors to consider when purchasing a UPS battery;


When choosing your UPS batteries, you should consider the batteries that can last for an extended period. Batteries that last for a short period are costly because you will require frequent replacements of your battery.


Know the size of the battery that your UPS backup system requires. Do not purchase before checking because you can end up purchasing over-sized or under-sized batteries.

Appliances To Be Protected

It is always excellent to know the number and size of the appliances you want to protect using your UPS. If you are using the UPS in your computer, only then pick the small units UPS, but if used to support the entire building or home, you will need to have UPS with higher units.


Cost always plays a crucial role in the purchase of any product. It is good to purchase batteries that will not affect your budget. But the price should not be considered so much that the quality is left out. What benefit will you get if you purchase a battery at a lower price but dies after a few days? You will get a significant loss from cheaper batteries.

Type Of UPS

There are three main types of UPS discussed above. They have different power consumption rates. Therefore, it is good to know the type of UPS’s power consumption rate that you are currently using.


It is said that preventing an accident before it happens is wise. Therefore, it is crucial to protect your devices before becoming a victim of damages or data loss. Install a UPS in your workplace, home, or business, and get the best results. Always ensure that your UPS has healthy and working batteries. (Article cited: large.net)
