Battery Replacement
What to Check Before Replacing UPS Lead-Acid Batteries
A practical project guide to checking the UPS, DC bus, battery strings, actual load, runtime, charger, cabinet and site before replacing a lead-acid battery bank.
UPS Battery Replacement Checklist
UPS battery replacement requires more than matching the old battery quantity. Use this checklist to review the UPS, measured load, runtime target, battery string, cabinet and retrofit options before quotation.
High-Voltage Lithium
How to Calculate UPS Lithium Battery Capacity from Load, Runtime and DC Voltage
Learn how to estimate UPS lithium battery capacity from actual load, backup time and DC bus voltage, and what must still be checked before final selection.
High-Rate vs Extended-Runtime LiFePO4 Batteries for UPS: How to Choose
A project-based comparison of High-Rate and Extended-Runtime LiFePO4 battery directions for UPS applications, focused on actual load, DC bus, charging, BMS and site evidence.
192V vs 384V vs 512V: How to Match UPS DC Bus Voltage to a LiFePO4 Battery System
A project-based guide to comparing 192V, 384V and 512V UPS lithium battery directions through the DC bus, voltage window, load, runtime, charger and BMS requirements.
Why UPS kVA Alone Cannot Size a Lithium Battery
A 100 kVA UPS does not point to one lithium battery. Compatibility starts with the exact UPS DC system, charger, load, runtime, BMS, protection and project conditions.
Server Room & Small Data Center
Small Server Room UPS Design & Selection Guide
Choosing a UPS for a small server room requires more than adding equipment wattage. Review the measured load, phase, power quality, runtime, batteries, monitoring and service conditions before quotation.
Engineering & Compatibility
CAN & RS485 in UPS Lithium Battery Projects: What Must Be Confirmed
CAN or RS485 hardware alone does not prove UPS lithium battery compatibility. Review the exact protocol, data points, settings, control logic and DC-side project evidence before approval.
UPS DC Bus Voltage Checklist for Lithium Battery Projects
A technical pre-RFQ guide to collecting the UPS DC voltage window, minimum voltage, charging, string architecture, actual load, runtime, BMS and site evidence required before lithium battery selection.
