Best Practices
UPS Sizing Tips
Avoid common mistakes and protect your critical infrastructure.
Size at 70-80% Load
Never run a UPS at full capacity. Operating at 70-80% load extends battery life and provides headroom for power spikes.
Plan for Redundancy
Mission-critical systems should use N+1 or 2N redundancy. A failed UPS with no backup is equivalent to no UPS at all.
Replace Batteries on Schedule
UPS batteries degrade over 3-5 years. Schedule proactive replacements before failures occur during an actual outage.
