Retrofitting Data Center UPS: The Hidden Dangers of Lithium vs. the WEST Advantage**
When upgrading from legacy lead-acid (VRLA) UPS systems, many data centers consider lithium-ion as the next step. But here’s what doesn’t always make the headlines: lithium retrofits often require specialized fire suppression systems, adding cost, complexity, and compliance headaches.
Why?
- Lithium-ion batteries carry a real risk of thermal runaway and fire, especially under high load or in extreme temperature scenarios.
- Most jurisdictions mandate advanced fire suppression and monitoring for lithium installations—sometimes even structural changes to existing spaces.
**There’s a safer way forward.**
WEST supercapacitor-based energy storage eliminates fire risk entirely. No thermal runaway. No specialized suppression. No sleepless nights for facilities managers. Wright Energy Storage Technologies
**Key benefits of WEST retrofits:**
- Operates safely from -40°C to +60°C
- Ultra-fast charge/discharge
- 10-year warranty (at 4/5C Rate, 20yrs at 3C or below)
- No hazardous chemicals or fire risk
- Seamless integration—no need for expensive suppression upgrades
