I. The selection and design of UPS batteries for data centers must take full account of the characteristics and development trends of modern data centers. At the same time, the following principles must be met.


1. Short time constant power output characteristics shall be excellent

Excellent short time (usually ≤ 30min) constant power output characteristics, which means that the capacity of the battery can be reduced to meet the same load backup time requirements, thereby reducing battery costs; or use batteries of the same capacity to increase the total backup time of the UPS system.


2. High energy density

Selection of appropriate battery type and capacity, design a reasonable assembly structure, optimize the use of space, improve the overall energy density of the battery pack, which helps to reduce the area and cost of the room.


3. High stability

During the effective life of the battery, there should be a low failure rate, try to avoid the repair or replacement caused by individual battery failure or sudden failure, which is of great significance to the late safety and stability of the battery system.


4. Fire retardant

Plastic material of UPS battery container in data center should meet the V0 flame retardant standards; all exposed metal parts like battery terminals, connectors and output bus terminals should be done to protect the insulation treatment, the battery rack needs to be grounded.

 

5. Consistency

About single battery of UPS battery pack in data center, the open circuit voltage, float voltage and other indicators of consistency should meet the relevant standards.

 

6. Earthquake resistance

 The design of UPS battery rack in the data center meets the requirements of grade 8 intensity, and it is recommended to use a soft connection for the connection between the batteries.


7. Easy to install and expand

The modular structure design of the battery and the provision of special installation tools can reduce the overall installation cost. The location of the battery pack and the design of the battery pack frame should be reserved for the location requirements for later capacity expansion.


8. Easy maintenance and replacement

The distance of battery pack placement and maintenance channel should meet the requirements of daily maintenance and battery replacement.

 

9. Long service life

UPS batteries in data center should be reasonable life requirements, too short life will increase the instability and cost of UPS systems.


VRLA batteries for backup purposes are divided into 2V, 6V, 12V and other series according to the individual voltage level. According to the way to store the electrolyte it can be divided into AGM (ultra-fine glass fiber) battery and GEL battery.


II. Maintenance cycle.

(1) There is no clear rule on how often the batteries in the server room should be replaced.

(2) Enterprises can choose the best replacement time according to their own needs.

(3) Replacement time and the battery material, warranty period, the number of charge and discharge, internal resistance changes, battery room temperature, humidity and cleanliness and other environmental factors should be considered.


Replacement of UPS batteries, seemingly simple, in fact, for an operating machine room is not so easy. Since the safe operation of the server room is involved, there is a lot of work to be done from communication to determining the plan to receiving materials and organizing the construction, and each construction step cannot be wrong If you have any request to replace the battery in your server room, please contact BETTER and we will provide you with a solution.
