Why is lithium-ion all the rage at the moment and is it worth it?

Why is lithium-ion all the rage at the moment and is it worth it?

If you’re new to batteries, or not so new but need some refreshing, let’s start with the batteries available and their advantages and disadvantages.

Looking at four types of UPS batteries:

  • Sealed Lead-Acid (SLA) / Valve Regulated Lead-Acid (VRLA)
  • Advanced Lead-Carbon (ALC)
  • Nickel-Cadmium (Ni-Cd)
  • Lithium Iron Phosphate (LiFePO4) 

Sealed Lead-Acid UPS Batteries 

These are the most common battery used when it comes to UPS systems. Over time they have shown to be reliable and the most cost-effective option. We commonly use sealed lead acid batteries which are also able to be moved and stored vertically or horizontally which suits various applications.

Cons of SLA batteries are their weight and size, so they are great in applications where size and weight are not an issue. 

Advanced Lead-Carbon UPS Batteries 

The accumulation of lead sulphate within a Sealed Lead-Acid battery due to partial charge and aging is often the cause of failure. Advanced lead-carbon (ALC) solves this by adding carbon to the negative plate and improving charge and discharge performance.

ALC batteries have the same cons with their weight and size. 

Nickel-Cadmium UPS Batteries  

This option used to be very popular and although they are used in some applications, they are no longer commonly used in UPS systems.

Advantages to Nickel-Cadmium batteries is the 20-years design life and the vast temperature range the batteries can operate in.

Cons of these batteries are the costs associated with the initial purchase and in disposing and recycling due to nickel and cadmium being toxic materials. 

Lithium Iron Phosphate UPS Batteries 

These batteries have been used for a number years in other devices and recently there has been a demand for lithium-ion in a UPS application. Advantages of Lithium-Ion batteries include their energy density, lighter weight, design life and the ability to charge more efficiently and in less time.

Cons of this option would be the cost, despite decrease costs recently they are still significantly more expensive than the VRLA option. Much like the Nickel-Cadmium batteries, there is a cost associated with disposal. There are issues with regards to transportation of Lithium Iron Phosphate batteries which could also have a significant impact on the disposal costs.

Overall, is it worth it?

That would depend on the individual application that is required, if weight and size are an issue and there is a larger budget available, they could be a viable option.

We have a large range of our UPS solutions that are compatible with lithium-ion batteries, for more information please contact us.

What is the Difference Between Square Wave and Pure Sine Wave Inverters?

What is the Difference Between Square Wave and Pure Sine Wave Inverters?

“Do you want get a Sine Wave Inverter or Square Wave Inverter?”

Perhaps, this is one of the most common questions you’ll get when you try to purchase a power inverter. So what’s an inverter anyway? The majority of household electrical appliances use an Alternating Current (AC) electricity. On the other hand, a battery stores Direct Current (DC) electricity. The main purpose of an inverter is to convert the DC electricity into AC electricity.

But when it comes to the basis of its circuits, an inverter converts DC current to either Square wave AC current or Sine wave AC current. The Sine wave inverter output is very similar to the AC current. In comparison with the Square wave output, the Sine wave output is purer; that’s also the reason why the term Pure Sine wave inverter exists.

To give you an idea of how the two currents look like, refer to the photo below:

One more important thing that you need to know is many household devices get heated up if you’ll use Square wave inverters. This is the reason why Square wave inverters are banned in some European countries. Other than that, we outlined a comparison chart between Sine wave inverters and Square wave inverters below to help you differentiate them better.

Comparison Chart: Square Wave Inverter vs. Sine Wave Inverter

List of FeaturesSquare Wave InverterSine Wave Inverter
 

 

Supported Appliances

 

Square wave inverters are usually used to support motors alone.

Sine wave inverters are used to support household appliances such as refrigerators ovens, computers, laptops, etc.
 

Overall Safety Level

Square wave inverters are less reliable and also unsafe to use for appliances.Sine inverters are highly safe to use.
 

Noise Interference

Square wave inverters produce a very loud noise when used.Sine wave inverters produce normal sound only.
 

Cost

Square wave inverters are less expensive than Sine wave inverters.Sine wave inverters are more expensive than Square wave inverters.

Furthermore, there’s another type of inverter that you can take advantage of. This one is called “Modified Sine Wave Inverter.” This type of inverter is better than the Square wave inverter and more affordable than the Sine wave inverter. A Modified Sine Converter can be utilised for simple systems, however, there are heaps of equipment that it cannot support. Some of these are the following:

  • Medical equipment (e.g. oxygen concentrators).
  • Some laptop computers.
  • Home Automation Systems.
  • Anything that has Silicon-controlled Rectifier (SCR).
  • Laser Printers.
  • Photocopiers.
  • Appliances with microprocessor controls.

If you are planning to purchase a Modified Sine wave inverter, it is highly recommended to go for the Sine wave inverter instead. As modern technology continues to rise, the cost of pure sine wave inverters is dramatically decreasing, making them more affordable and accessible in the global market.

How Long Does a UPS Battery Last For? 

How Long Does a UPS Battery Last For? 

“Well, how long is a piece of string?”

This is probably one of the most frequently asked questions by customers who are planning to purchase an Uninterruptible Power Supply (UPS). While it is understandable for consumers to be concerned about the capacity of their power source, determining the exact life span of a UPS battery is pretty hard to do.

Unlike the typical alkaline batteries, the life a UPS battery depends on a number of impacting factors such as environmental conditions, maintenance, and the number of discharge cycles. However, the standard capacity of a UPS battery is three to five years, depending on the factors that may affect the performance of the UPS.

All UPS manufacturers never fail to remind their consumers that the UPS battery is the most vulnerable part of the entire system. Thus, learning how to manage and maintain your UPS batteries properly will extend their overall capacity and will also help you save time and trouble in the future.

When it comes to environmental conditions, there is a set of standards that need to be met to get the maximum life out of your battery. We have listed some of these factors:

  1. Room Temperature

It is essential to recognise that ambient temperature can alter the performance of a UPS battery and can potentially shorten its expected life span. The optimum temperature to store a UPS in is  21°C – 25°C. The maximum temperature to store a UPS in is 50°C, however when the temperature increases or decreases from the optimum range, this is when it begins to affect the life span of a battery.

PSS Distributors sell a range of 19”racking systems, as well as fans and aircons to help keep critical equipment and UPS at their desired temperature.

  1. Regular Maintenance

No matter how well-kept your batteries are, they still need to undergo proper maintenance. Neglecting to do such safety measure may cause your UPS batteries to experience improper loading, heat-generating resistance at the terminals, loose connections, premature failure, and reduced protection. Some UPS models require extensive maintenance since regular checkups are critical to their overall reliability.

  1. Cycling

During a power outage, UPS operates using its own battery power. Once that power has been fully restored, the battery will then get recharged for future use. This process is called a discharge cycle. When the UPS was first installed, the battery’s rated capacity is at a hundred percent. However, each discharge cycle reduces the relative capacity of the battery by a small percentage.

  1. Battery Chemistry

Unfortunately, UPS batteries are electrochemical devices and are not designed to last a lifetime. Even if your UPS batteries are well-maintained and meet the specific standards for proper storage, your batteries will still run out of power, and you will be required to do a replacement after a particular period of time.

Overall, even though UPS batteries don’t last forever, following the guidelines that we have provided above, you will surely be able to maximise your UPS life span.

If you’re currently planning to replace your UPS batteries with new ones, we can service and maintain a wide range of UPS, we are now fully staffed nationwide;

Recycling

Discarded electronic equipment is one of the fastest growing waste products today due to the increasingly large usage of these products. This needs to be monitored responsibly and methods used such as effective collection, reuse and recycling. Each person using these products can also make the right and responsible decision for discarding their equipment.

Electronic equipment waste contains hazardous material which is harmful to the environment and human health and this waste is growing three times faster than general municipal waste.

Governments and organisations are working closer with such projects.

At PSS – we take discarding of our old electronic items and batteries very seriously and ensure our methods comply with safety standards.

We strip out units and recycle the parts. We also offer a service to our customers whereby we discard their old batteries for them.

Please call us on 130088447 for assistance or information.

Importance of servicing UPS

Although most of the modern units test batteries periodically, if is always good to power the UPS every 6 months.

This is done by switching the power off to the UPS and monitoring DC voltage. Once the batteries reach 20% capacity, re-instating power. This cycles the battery, prolonging their service life.

If the batteries do not perform to specification, they should be replaced by a qualified service technician and old batteries disposed of correctly.

The 5 biggest mistakes made when ordering a UPS

The 5 biggest mistakes made when ordering a UPS

1.       Not knowing their load- If the load is not known, it’s like buying a Ute and not knowing what payload needs to be carried

2.       Not knowing what battery time is needed- this is determined by the load requirements

3.       What format and weight of UPS- UPS com in rack mounted or floor standing units and are primarily manufactured from copper and lead.

4.       Power to supply UPS- in most cases when one big UPS needs to supply critical equipment, the load needs to come from one adequate supply.

5.       No budget set aside for electrical work- When supplying a UPS that cannot be plugged into a 10A GPO, the UPS need to be wired in by a qualified electrician.

Our handy UPS calculator addresses most of the above questions making it an extremely useful tool when buying a UPS.

What’s an IP rating?

IP (or “Ingress Protection”) ratings are defined in international standards. They are used to define levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies (tools, dirt etc.) and moisture.”

Should UPS ever be switched off?

No, the only time UPS should be switched off is when the load on the UPS has been removed. This can be done in the following conditions:

  1. The load has been transferred to another source
  2. In a parallel redundant system, when the redundant unit can accept full load
  3. The load is switched off entirely.

Therefore it is essential to maintain and test the UPS and batteries during scheduled times that is convenient to all parties.

Advantages of service contracts

From research carried out by various UPS companies, it has been shown that the chance of UPS failure is nearly four times greater when the unit is not regularly checked and serviced.

PSS Maintenance contracts include two site visits per year where PSS technicians will check the condition of the UPS and advise if any issues. We will test batteries, run discharge tests to establish battery life, check operating parameters as well as perform any required adjustments.

Our all-inclusive service contracts are designed to offer 24 x 7 peace of mind protection for our customers; we will take ownership of all UPS related matters and deal with them promptly.
