When it comes to choosing a UPS (Uninterruptible Power Supply), the type of battery is critical. Some batteries perform better than others. For example, LiFePO4 and lithium-ion batteries are two popular types used by UPS makers but there are others. 

What are these different battery technologies, and why is battery type important in UPS design? Which battery type is best for a UPS device? We discuss these points in the article. 

Understanding LiFePO4 and Lithium-ion Batteries for UPS Backup

A power outage can throw you into the dark and potentially damage your devices. But this is when you need a UPS (Uninterruptible Power Supply). A UPS system does not need a switchover. It recognizes when power is gone and switches on. So you don't lose valuable work or devices due to unstable power. 

Introducing UPS Battery Technology

Why does battery choice in a UPS matter? Wouldn't any battery be enough? The reality is, battery quality differs. Some batteries are more durable than others. Maybe you know a UPS device that no longer works after being in use for some months. You can avoid the negative experience by making an informed choice. 

Why Battery Choice Matters in a Power Backup System

A UPS system will protect your sensitive electronics during a power cut or outages. Also, your gadgets and Wi-Fi will remain on so you don't lose data. But a UPS is only as good as the battery it runs on. 

The type of battery will affect the device runtime, number of charge cycles, and device safety. So what are some common battery types used for UPS systems?

Overview of Common UPS Battery Types

Lead-Acid: This is common in older UPS units but its use has declined. Lead-acid units tend to be bulky, heavy, and prone to sulfation. Also, they are not very durable, with a cycle life of just 500. 

Lithium-ion (Li-ion): These are popular for their high energy density. This means that even a tiny unit can hold a lot of power. Li-ion batteries are also common in phones, laptops, and electric vehicles.

LiFePO4 (Lithium Iron Phosphate): It's a newer type of lithium battery. They are common in UPS devices due to their safety, long life, and steady power output.

What Are Lithium-ion and LiFePO4 Batteries?

Since lithium-ion and LiFePO4 batteries are more common in modern UPS designs, we’d compare them below:

How Lithium-ion Batteries Work

Lithium-ion batteries store energy using a lithium-cobalt or lithium-manganese compound. They are very common in electronics and electric vehicles because they are lightweight and can pack a lot of energy into a small space.

Pros of Lithium-ion Batteries

• Li-ion batteries are energy dense. 

• Due to their chemical makeup, they are lightweight. This helps device portability. 

• Li-ion UPS supports the convenient fast charging feature.

Cons of Lithium-ion Batteries

• The batteries are heat-sensitive and may experience reduced performance in hot weather. 

• A Li-ion UPS has a short lifespan of just 1000 cycles. Hence, you'll need to replace the battery sooner. 

• The lack of thermal stability means there is a higher risk of overheating or fire. This makes it less safe in UPS units.

How LiFePO4 Batteries Work

LiFePO4 batteries use lithium iron phosphate as the cathode material. As a result, they have a stable chemistry and are less sensitive to heat. 

Pros of LiFePO4 Batteries

Longer Life: The batteries can last up to 5,000 cycles. So, a LiFePO4 UPS can last up to a decade. 

Better Stability: There is a very low risk of fire or explosion, even when operated in unfavorable weather. 

Great for Standby Use: The batteries are safe and durable. Thus, they are great for UPS and solar storage uses where portability and weight are not major issues.

LiFePO4 vs Lithium-ion for UPS Backup: Core Considerations

Let’s compare these two battery types based on these 5 different criteria: 

1. Safety and Thermal Stability

2. Cycle Life and Longevity

3. Performance Under Load

4. Weight and Size Considerations

5. Cost Comparison: Upfront vs Long-Term

Safety and Thermal Stability

Lithium-ion batteries can overheat if they carry much load. In worst cases, they may swell or catch fire.

In contrast, LiFePO4 batteries are much safer. They can handle high temperatures and stress without failing. This makes them a good choice for indoor use. The chances of an accident are unlikely. 

Cycle Life and Longevity

If you want a battery that lasts, LiFePO4 is the better choice. It can handle thousands of charge and discharge cycles without losing capacity. So you don't have to replace them soon. This can save you long term costs. For a long-lasting UPS device, LiFePO4 battery chemistry is the best.

• Lithium-ion: 500 - 1,000 cycles

• LiFePO4: 2,000 - 5,000+ cycles

Performance Under Load

When blackouts happen suddenly, the UPS may experience an instant electrical surge. LiFePO4 batteries handle this load better than most lithium-ion cells. Also, they maintain stable voltage, which is crucial for sensitive devices like routers and smart TVs. 

Weight and Size Considerations

Lithium-ion batteries are lighter and smaller. So they are common in power banks and other portable devices. But for stationary UPS units, weight is not a pressing concern. Their stability and lifespan make up for the added weight of LiFePO4 batteries. 

Cost Comparison: Upfront vs Long-Term

You pay more initial cost for a LiFePO4 battery. However, because it lasts longer, this is a good investment. So, while Li-ion batteries are cheaper, LiFePO4 is a better value for money. See our article on how to choose a UPS system. 

Why Goldenmate UPS Products Use LiFePO4

If you are getting a UPS, consider a Goldenmate product. Our batteries and UPS products all use the LiFePO4 battery type. Why have we used a superior battery type?

Designed for Longevity and Reliability

At Goldenmate Energy, we focus on building safe and durable UPS solutions. That is why we use LiFePO4 batteries for all UPS products. The result is that you can use these units indoors for up to a decade and counting. 

Real-World Applications

Also, our UPS systems do serve a variety of uses in the real world. For example, some clients use them to back up workspaces, gaming rooms, surveillance systems, and medical clinics. So you can trust our UPS for your needs.

Features of Goldenmate UPS Systems

Durable LiFePO4 Battery Life: LiFePO4 batteries last very long. All our UPS products use this battery type. The result is that your unit can withstand 3000+ cycles or 10 years of usage. Most UPS systems do not last this long. So they cost you extra to replace after only a few months or years.

Increased Device Protection: The outlets have surge and battery protection. Also, the BMS (Battery Monitoring System) in the units ensures current is stable and safe for use. You can monitor the status of your unit by looking at the LCD screen.

Maintenance-Free Usage: There is no special maintenance. You only need to occasionally wipe dust off the unit. So using the UPS system is very convenient and stress free. 

Final Verdict: Which Battery Wins for UPS Backup?

So how do LiFePO4 and Li-ion batteries compare when it comes to UPS devices? See the summary below:

 

A Li-ion battery is the more portable and budget friendly choice. But these are secondary concerns when choosing a stationary device such as a UPS. Often, users are more concerned with durability and safety. These are areas where LiFePO4 shines.
