Engineering white papers and field case studies on UPS batteries, sizing and replacement, written by GDF Technologies for Canadian buyers. Every piece is sourced from published manufacturer and standards data.
White Papers
Replace the battery or replace the UPS: a decision framework
When to replace the batteries versus the whole unit — a break-even method you can run with your own quotes.
Read →Case Studies
Buying runtime within the same footprint
Gaining runtime by stepping the cell rating before enlarging the cabinet.
Read →Sizing a replacement VRLA battery string from DC bus voltage
How the DC bus voltage sets the block count, and how the right flame-retardant cell is chosen.
Read →Qualifying a higher-capacity battery in an existing cabinet: 12AVR100 to 12AVR130
More autonomy without a new cabinet — the fit and electrical gates a larger block must pass first.
Read →Qualifying an urgent VRLA battery substitute when the preferred stock is unavailable
How to keep availability from replacing engineering when a preferred battery is on backorder.
Read →Extending APC Smart-UPS SRT runtime without guessing the battery pack
A composite server-room case built around exact SRT pack matching, load evidence and a witnessed battery test
Read →Responding to battery alarms across a mixed APC Smart-UPS retail fleet
A composite multi-site case that separates alarm triage, exact battery identification and controlled rollout decisions
Read →Planning an APC Symmetra LX battery-module intervention around access and redundancy
A composite critical-load case using SYBT5 identification, lifting controls and an explicit operating-state gate
Read →Choosing VRLA or lithium-ion batteries for a Schneider Galaxy UPS expansion
A composite data-centre decision that compares complete supported architectures rather than treating battery chemistries as interchangeable
Read →Adding Eaton 9PX external battery modules with a verified voltage-family match
A composite edge-computing case that turns an autonomy request into an exact UPS, EBM and test record
Read →Deciding whether an Eaton 9130 needs a battery bridge or a UPS replacement
A composite lifecycle case that separates short-term battery service from the supported 9PX or 9SX migration path
Read →Assessing an Eaton 93PM battery bank before a maintenance outage
A composite three-phase case that separates observed condition, trend evidence and replacement scope
Read →Expanding Vertiv Liebert GXT5 runtime with the correct external battery cabinet
A composite rack case that uses Vertiv’s compatibility table, cabinet detection and measured-load acceptance
Read →Diagnosing a failed battery test on a discontinued Vertiv Liebert GXT4
A composite lifecycle case that avoids turning one alarm into an automatic battery or UPS order
Read →Standardizing battery replacement across a Vertiv Liebert PSI5 edge fleet
A composite distributed-site case that keeps exact PSI5 models, battery types and handback evidence separate
