Why UPS Battery Supply Units Are Very Important

Uninterrupted power supply systems were developed mainly to help people enjoy using their computers even with uneven power flow from the grid. The system as a whole is therefore very useful. However, there are parts within which shoulder most of the burden. These include the UPS battery supply units among others.

When there is an interruption in the power flow, the batteries provide an alternative source. The only exception is when one has a flywheel energy storage system, which are very rare. With every blackout, the batteries help fill the vacuum until an alternative source such as a generator is started or the power from the grid returns.

For people with a simple system such as a home computer, the unit serves the purpose of providing them enough power to switch of the machine safely. This is because most of the systems have simple internal batteries that cannot last long enough for other purposes. With this limitation, people are seeking new ways to make their systems more useful.

The use of external batteries in blocks is one such alternative as it helps extend the time served by the internal battery. This extends the time offered by the system from a few minutes to 4 or even 6 hours of full power for the system. With such an option, it is possible to use the power for other purposes not just powering the computer.

Even though this option promises more benefits, you should note that it is as strong as its weakest battery. This means you must have a systematic way of testing the extra battery supply units. This will help you identify and replace any weak links in the system even when they have not fulfilled their expected life cycle.

The testing takes different approaches. There is the option of automatic testing carried out by the UPS system. You can also opt for load bank or electro chemical testing. With the automatic option, the system tests the system every 24 hours and plays an audio warning if any unit has a problem.

Although the automatic testing option is the quickest way to identify a problem, it is not very reliable. This means that one also needs to use the other two methods for proper analysis of the problem. Once you identify the source of the problem within the UPS battery supply units, you should replace it immediately even when it has not exhausted its expected lifespan, which is usually five to ten years for most of the units. After this, your system should function properly.

On the outside, it looks plain and simple, but on the inside, it’s very different. The Lancer has all the functionality you need in a laptop bag and it has an excellent design. But I do have one flaw to mention: it’s quite heavy. For a bag without load, 3.6 pounds is already burden enough on the back. And with all the stuff inside it, who knows how heavy your bag will be? The design made up for it, though, because it has a feature for weight distribution. The dimensions of the bag are 19.50″ x 3.25″ Width x 14.50″, a little thinner than other models of the same size, but the compartments can be expanded so the depth gets bigger if the bag is full.

The bag exterior is made of polyester and vinyl, two durable materials to ensure the long life of the product. If you use it properly, it will definitely last for many years. Its features are very good for daily use, like the weight distributing feature that I mentioned previously. The shock absorber shoulder straps distribute the weight evenly and decrease the strain on your shoulders so it doesn’t feel too heavy when you carry it. Along with that is the airflow back system which provides a breathable back padding, keeping you cool even if you’ve been carrying the back for a long while. The bag also makes use of the trademark SWISSGUARD computer pocket hich provides maximum protection and comfort for your beloved device.

The Lancer has four compartments: a front pocket, an organizer, a middle compartment, and the laptop compartment. The front pocket is a small space where you might want to keep tiny things close at hand, like USB devices or coins. The second compartment is an organizer with pockets especially for a cellphone, ball pens, and other small devices and office supplies. The third compartment is where you keep textbooks and other papers and documents, since it is the most spacious of all. The last compartment is where you keep your laptop. You can also squeeze in some papers and notebooks in there, or if you have two laptops, they can snugly fit in there as well.


The bag is a nice red hue, with a black body and highlights of gray. The color is great for keeping stains out of sight and hiding any signs of damage and weathering. It also makes the bag very fit for anybody’s use. People of all ages, genders, and professions can use. Whether you’re a professional who uses his laptop for work everyday or a college student who needs his laptop for school, you can benefit from the great features of the Lancer.

Other Features

The bag has a storage area for music players like iPods and MP3 players and there’s also an earphone outlet so you can listen to your favorite tunes while wearing the bag. The bag has two strap handles, and one can functions as a trolley strap so you can easily mount the bag on a rolling suitcase for easier travel. It also has a case base stabilizer platform which keeps the entire bag upright no matter how bulky it is inside. This keeps the laptop safely tucked in your bag, and you don’t have to worry about it getting damaged or accidentally stumbling over.


If you read this entire review, then you must have an idea how great a bag the SwissGear GA-7323-13F00 Lancer Notebook Backpack really is. Forget about its heaviness – all other features make up for that single flaw. And besides, a light backpack is made of light material which might be easily damaged and worn. But the Lancer is designed to last for years, and that’s what it can do. Mine did, and until now I’m very satisfied with using it.
