Why This Matters
Batteries Don't Last Forever
Most UPS failures happen because batteries were never tested or replaced on schedule. Don't wait for the next outage to find out.
Know Your Actual Runtime
UPS rated runtime assumes new batteries at specific loads. Reality is different — especially with aging batteries under varying loads.
Track Battery Health
VRLA batteries degrade quickly after 3 years. Lithium-ion lasts longer but still loses capacity. Track degradation and plan replacements proactively.
Prevent Downtime
A UPS with failed batteries provides zero protection. Know exactly when to replace batteries before they leave your infrastructure exposed.
