How to Extend the Life of Your UPS

As winter approaches, the risk of power outages rises as cold weather and extreme conditions strain electricity networks. Weather-related outages are increasing, so a robust power-protection strategy is essential. Preventative maintenance on your Uninterruptible Power Supply (UPS) is therefore non-negotiable.

For businesses, that means ensuring reliable power protection. A UPS keeps operations running during interruptions, but like any equipment it needs regular maintenance to perform when it matters most.

This guide outlines preventative tasks that extend UPS life and reduce downtime. Take these steps before the cold sets in to keep your business ready, whatever the weather.

1. Check and test your UPS batteries
   Batteries are the heart of your UPS, providing runtime during a failure. They degrade over time, losing capacity.

The National Energy System Operator’s latest outlook suggests the grid is prepared for winter, but conditions may be tight, particularly in early December or mid-January. Reliable batteries are critical in these periods.

How to test:
• Battery discharge test: Prove the battery can support the expected load and confirm actual backup time.
• Voltage check: Verify voltages are within the manufacturer’s limits; low readings can indicate declining health.
• Age review: Most UPS batteries last 3–5 years. Replace ageing sets or those that fail tests. Check production dates and manufacturer guidance.

2. Inspect and clean the UPS cooling system
   UPS units generate heat; overheating reduces efficiency and can cause failure, especially in warm plant rooms during winter.

What to do:
• Clean fans and vents to restore airflow.
• Check fans for noise or slow running; replace if necessary.
• Ensure clear ventilation around the UPS; avoid confined spaces that restrict airflow.

3. Monitor environmental conditions
   Temperature and humidity strongly influence UPS reliability.

Good practice:
• Keep temperatures cool and stable for best performance.
• Control humidity to prevent corrosion; use dehumidifiers where needed or relocate the UPS to a controlled area.

4. Test your UPS under load
   A UPS must support your real load when the power fails.

How to verify:
• Simulate an outage with a load bank or controlled test. Confirm the UPS carries critical systems.
• Check runtime against expectations; shortfalls may indicate battery wear or undersizing.

5. Review maintenance history and book professional servicing
   Proactive service prevents minor issues becoming critical.

Actions:
• Maintain detailed service logs to track parts replacements and recurring faults.
• Schedule periodic inspections by a qualified engineer to test, fault-find and verify safe operation.

6. Prepare a clear winter emergency response plan
   Even with good maintenance, outages can occur. Ensure your team knows what to do.

Include:
• Procedures for safe shutdowns, switching to backup power and contacting support.
• Communication plans to update staff and customers about disruptions. For general guidance, see the National Grid’s power-cut advice or the British Red Cross’s emergency preparation resources.
