Small in size but big on power, this power solution is more reliable
In daily work, ensuring a stable power supply for low-power devices is equally crucial, whether it's cash registers, security cameras, or network equipment. Many users habitually opt for traditional lead-acid battery UPS as backup power sources. However, for low-power loads, this could be a misconception!
Why are lead-acid battery UPS unsuitable for low-power loads?
- "Over-light Load" Damages Battery Life
When the UPS capacity is significantly greater than the load power (e.g., using a 3KVA UPS to power a 300W device), a power outage can lead to deep battery discharge, significantly shortening the lifespan of lead-acid batteries. Industry experts point out that such an application scenario, where the UPS's capabilities are underutilized, can actually cause premature battery failure. - Bulky Size, Low Space Utilization
Traditional lead-acid battery UPS units take up valuable space, which is highly unfavorable for low-power application scenarios. These scenarios often lack dedicated machine rooms, and devices are typically deployed in office spaces or even business areas. - "Memory Effect" in Low-Current Discharge
When lead-acid batteries supply power to low-power loads, low-current discharge can trigger a noticeable memory effect, accelerating battery capacity degradation. - High Temperature Sensitivity
The lifespan of lead-acid batteries decreases exponentially when the temperature exceeds 25℃. For instance, at 45℃, their lifespan may drop from 5 years to just 1-1.5 years. This is a fatal weakness for small devices lacking a constant-temperature environment.
A Better Solution: The Advantages of Lithium Battery UPS Shine Through
Lithium battery UPS units offer significant advantages tailored to the specific needs of low-power loads:
- Unaffected by Light Loads: Lithium batteries have no memory effect, so low-current discharge does not affect their lifespan.
- Compact Size: Compared to lead-acid battery solutions of the same capacity, lithium battery UPS units save up to 60% in space and reduce weight by 70%.
- Doubled Lifespan: Their cycle life is 3-5 times longer than that of lead-acid batteries, reducing replacement frequency and costs.
- High Depth of Discharge: They can be deeply discharged without damage, greatly improving battery utilization.
When it comes to lithium battery UPS units, we must mention HIGHIDEA , a brand that has focused on R&D for 15 years. As one of the early adopters of lithium battery UPS technology in China, its products use lithium iron phosphate cells with a cycle life of over 2,500 times. For low-power scenarios, HIGHIDEA has launched the LT series, which is compact in size and offers long battery life.
[Tip] Regularly performing charge-discharge maintenance on your UPS (recommended every 4-6 months) can effectively activate battery performance!
