What is the best way to maintain UPS BATTERIES?

Uninterruptible Power Supply (UPS) is critical for the reliable operation of data center and IT equipment. They provide backup power to connected devices and ensure they keep running during power failures, power surges, or other power fluctuations. Essentially, The UPS acts as an insurance policy against the high cost of unplanned downtime. Considering that data center is more critical than ever in generating revenue and enabling e-commerce, downtime is not an option for most businesses currently. Therefore, it is crucial to understand the protection provided by UPS battery warranties and the best ways to maintain UPS battery life.  

What Does UPS Battery Warranty Cover?

Most UPS batteries come with a warranty that ranges from 24 to 72 months. The battery warranty is designed to ensure and cover the manufacturing quality and performance of the battery. However, it is important to note that the warranty does not cover the normal damage of performance due to battery ageing or use. Additionally, many warranty periods are only valid with professional starting batteries and regular annual maintenance. You will need to keep service records to substantiate any warranty claims you may have to make. In other words, relying solely on warranties to protect your UPS batteries and your business is not recommended.

What's the Best Way to Maintain UPS Batteries?

With the growing demands on data centre managers and internal IT staff, it is not uncommon for UPS battery replacements or maintenance to be delayed or overlooked. However, UPS battery maintenance is necessary to meet regulatory requirements and optimize battery performance.

Battery Minimum Maintenance Requirements

The Institute of Electrical and Electronics Engineers (IEEE) provides recommended practices for battery maintenance, testing, and replacement in stationary applications. They relate to the frequency and type of measurements required to verify the condition of various UPS battery types:

  • IEEE 450 VLA
  • IEEE 1188 VRLA
  • IEEE 1106 NiCad
Three Ways to Maintain UPS Battery Health

There are three ways to maintain UPS battery health based on organizational risk tolerance levels:


  1. Reactive:

This is the most dangerous approach because corrective action is only taken after the outage has occurred. This approach is only feasible when the consequences of downtime are not considered business-critical or when the budget is very limited.


  1. Time-Based Approach:

This approach involves regular preventive maintenance visits to visually inspect and maintain the UPS system, including batteries. While it has significant benefits than the reactive approach, it still has risk and does not take into account external factors that may cause UPS and battery life to be significantly shorter than expected.


  1. Proactive:

This approach involves a comprehensive maintenance program that includes component assessments and battery replacement programs. It is one of the most cost-effective measures to ensure emergency power system reliability and prevent costly downtime.

The Bottom line

In short, UPS battery warranties provide coverage for manufacturing quality and performance, but they do not cover normal damage of performance due to battery ageing or use. To ensure zero risk of unplanned downtime, a proactive maintenance approach is recommended.
