What is a Server Rack Battery?

Server rack batteries are a fairly new but trusted and reliable energy storage solution in the world of technology. These batteries are connected in series and stacked on top of each other, usually placed together in a rack (sometimes not) to make it compact.

Each connected battery is usually at least 12 volts and a maximum of 48 volts to make a large energy storage system, which could give an uninterrupted power supply to keep the devices up and running without electricity or in case of power outages.

Server rack batteries can be used in homes, offices, and other residential and commercial areas.

Choosing a Server Rack Battery- Criteria for Selection

Following are some of the factors to keep in mind while you look for the right server rack battery:


When choosing a server rack battery, it is very important to ensure it comes with proper safety certification. Keep such batteries in options that have relevant certifications, such as UL (Underwriters Laboratories) or other recognized standards.

Certification ensures that the battery meets safety and performance requirements, providing confidence in its reliability and making it easy to trust the product as well as the manufacturer.

 Cycle Life 

Consider the cycle life of the battery, which denotes the number of charge and discharge cycles it can undergo before significant degradation. Higher cycle life indicates a longer-lasting and more durable battery.

 Battery Management System

A robust BMS is essential for monitoring and managing the battery's health. It helps prevent issues like overcharging, over-discharging, and overheating, thereby extending the battery life and ensuring safe operation.

 Safety Features

Modern storage systems come with a variety of integrated safety features that can improve their performance, all the while contributing much to their level of security. These qualities include, among others, sensors for temperatures, overcurrent protection, and overcharging suppression.

 Runtime and Capacity

It's crucial to take the runtime and capacity into account when selecting a server rack battery for power backup because these two elements are mostly responsible for the battery's performance. Depending on the particular demands, the appropriate runtime and capacity may fluctuate. For larger configurations with significant power consumption, a larger battery with a higher capacity is appropriate. Batteries in the ranges of 48 V and 51.2 V 100 Ah are frequently used.


Assess the overall cost of ownership, considering not just the initial purchase cost but also factors like maintenance, replacement, and energy efficiency.

A slightly higher upfront cost may be justified by long-term savings and performance. you should also take installation costs into account while purchasing a server rack battery.
