### Introduction
With even momentary electrical power loss capable of interrupting business operations and leading to extensive data losses in an era like ours, a dependable Uninterrupted Power Supply (UPS) system becomes indispensable. Inside every UPS system lies the very heart of it; this is what powers up all but the most power hungry devices feeding your computer, server or other gear: a battery. Different types of UPS batteries can make it confusing to decide which is best for your requirements. This is part two of our UPS battery เช่า แบตเตอรี่ ups guide, and in this article we are going to look at different types of batteries used for your power backup system (UPS).
There are several types of UPS Batteries
You can fundamentally select from three varieties of UPS batteries: valve-regulated lead-acid (VRLA), flooded lead-acid (FLA), and lithium-ion (Li-ion). These battery types have different strengths and weaknesses, making them more or less appropriate for different situations.
#### 1. VRLA (Valve-Regulated Lead-Acid) Batteries
Type used in UPS: VRLA batteries, a.k.a., sealed lead-acid batteries are the most common types of battery by far on small to medium size systems. These scales are used widely because of their easier maintenance and also for the ease in price. Since VRLA batteries have seal properties therefore no frequent topping up with water which is required in FLA batteries. Plus they are less likely to leak, another important safety feature if you have limited maintenance access.
However, other kinds have a typical life span of just 3 to 5 years. They also have a lower energy density, which makes them the bulkier and heavier option when compared with lithium-ion batteries. While these may sound like limitations, VRLA batteries are excellent for applications with a tight budget and where the UPS needs only to run without mains power for short periods of time.
#### 2. Flooded Lead Acid (FLA) Batteries
2- FLA batteries (Flooded Lead-Acid) — These are the common type of lead-acid battery and they have been around for quite a long time due to their robust construction which sometimes results in extended life. With proper care they can also last up to 20 years, which is why many large-scale UPS systems that need extended back-up times continue using them. That being said, Lead-acid batteries do require more maintenance such as checking water every so often and topping off if needed for something negative for users.
An FLA battery releases gasses when it charges and requires adequate ventilation wherever they are installed. The weight and larger size of battery cell types these batteries are competing against, for example VRLA or lithium-ion can be a disadvantage if space is tight. Nonetheless, FLA batteries are excellent for use cases that demand high levels of long-term resiliency and robustness.
#### 3. Batteries: Li-ion (Lithium-Ion)

While this is actually not as harmful for the environment as other batteries we burn through, they are still a lot more lightweight and space efficient due to their higher energy density. On top of that, lithium-ion batteries will last longer (up to 10-15 years typically) and they have a higher tolerance for charging/discharging than the lead-acid type.
Lithium-ion batteries also deliver quicker charging times. Lithium-ion batteries can charge much faster than lead-acid ones and are perfect for frequent blackouts. In contrast, the lithium-ion batteries are still too costly. Naturally, one limitation is that they are much more expensive than lead-acid batteries.
Which UPS Battery Type is Best for You?
Many factors make choosing the correct UPS battery type for your application difficult, such as: budget maintenance capabilities space constraints and specific needs of a power backup system
– **For Value/Cost Smart Users:** Consideration from the cost can be a VRLA battery. This makes them an elaborate balance of cost, maintenance and reliability for the most common applications in small to medium UPS systems.
– **Long-Term Reliability:** Want a battery that lasts several years and can be topped up regularly — then FLA batteries are the way to go. These units are ideal for large, critical loads that require extended duration runtimes.
For Space and Weight: If space or weight are key considerations, a lithium-ion battery is the proper choice (and you need one for fast-charging). Despite the higher price, they are also great for sites with frequent power outages.
### Conclusion
So, ultimately the selection of UPS battery type is very important for having good performance and reliability of your UPS system. Whether you choose the no-worry VRLA, the unbreakable FLA or a lithium-ion battery with bells and whistles to boot – each come grossly specialized. Knowing the ups and downs of each UPS battery type puts you in an informed position to make a decision that fulfills your power backup requirements with practicality.
When looking at the best UPS battery to add for your system, you should take into consideration some of the following factors: price cost; maintenance needs and upkeep levels (if any); life-cycle costs over time with other models aside from those previously mentioned only specific applications that suit one. A UPS battery เช่า แบตเตอรี่ ups, if chosen wisely, can provide you the reassurance that your important systems will continue to work even when there is a power-cut, hence keeping safe from any possible disruptions.
