Different Types of UPS Batteries

There are 2 main types of batteries used in Unipower's uninterruptible power supplies: Lead-Acid and Lithium-Ion batteries. There isn’t a single “best” UPS battery technology – the choice should be made on a case-by-case basis. 

我司不间断电源使用的电池主要有铅酸电池和锂离子电池。没有一种“最好”的UPS电池技术，应根据具体情况进行选择。

Lead-Acid UPS Batteries铅酸UPS电池

Lead-Acid batteries have a proven track record for reliability when used in an uninterruptible power supply system. In large power applications, where weight isn’t the overriding concern, they provide the most economical choice.This cost-effectiveness is combined with other performance qualities such as low internal impedance and high tolerance. 

铅酸电池在不间断电源系统中具有更高的可靠性。在大功率应用中，重量不是最重要的问题，它们提供了最经济的选择。这种成本效益与其他性能品质相结合，如低内阻和高公差。

This is the most common type found in modern UPS systems. They typically come with a 5 or 10-year design life and are best stored in a dry, climate-controlled room at a temperature of 20-25°C.  

这是现代UPS系统中最常见的类型。它们通常具有5年或10年的设计寿命，最好储存在温度为20-25°C的干燥的室内环境。

VRLA batteries are sealed inside a case which has a valve that vents to release gas if internal pressure gets too much, hence the term “valve regulated”.  

阀控密封铅酸蓄电池密封在一个外壳内，外壳上有一个阀门，当内部压力过高时，该阀门会排气以释放气体，因此也叫“阀门调节”。

Because they are sealed, they can be mounted either vertically or horizontally, so are suitable for use within battery compartments, rackmount trays or external cabinets. In addition, they don’t need any direct maintenance such as being regularly topped up with water.  

因为它们是密封的，所以可以垂直或水平安装，因此适合在电池室、机架式托盘或外部机柜内使用。此外，它们不需要任何直接维护，例如定期加水。

Lithium-Ion UPS Batteries 锂离子UPS电池

Lithium-Ion (Li-Ion) batteries have long been used in electronic devices such as laptops and smartphones, while they are now core elements in the growth of electric vehicles. But recently they are becoming an increasingly viable option for uninterruptible power supplies and other energy storage systems too.  

锂离子电池长期以来一直用于笔记本电脑和智能手机等电子设备，而它们现在是电动汽车发展的核心元素。但最近，它们正逐渐成为不间断电源和其他能源储存系统的可行选择

They are significantly smaller and lighter because of their significantly higher power density. They also have faster charge times, longer cycles, and at least double the service life compared to VRLA/SLA.  

由于功率密度明显较高，因此它体积更小、重量更轻。与铅酸电池相比，它们还具有更快的充电时间、更长的周期和至少两倍的使用寿命。

Despite the cost of Li-Ion UPS batteries decreasing over recent years, it is still a far more expensive initial choice than the other options.  

尽管近年来锂离子UPS电池的成本在下降，但它仍然是一种比其他电池昂贵得多的选择。

However, the longer service life does balance out the higher upfront capital costs. Li-Ion generates less heat and can operate at higher temperatures, meaning they don’t require as much air conditioning, which can reduce cooling costs.  

然而，较长的使用寿命确实抵消了较高的前期资本成本。锂离子产生的热量更少，可以在更高的温度下工作，这意味着它们不需要太多的空调，这可以降低冷却成本。
