J90-2kLiD vs APC Smart-UPS Ultra SRTL2K2RM1UC
The Xtreme Power J90-2kLiD and APC Smart-UPS Ultra SRTL2K2RM1UC are compact 1U online lithium UPS systems for space-constrained edge IT, network closets, and distributed infrastructure. Both deliver true online double-conversion protection; the J90-2kLiD differentiates with longer-life LiFePO₄ batteries, higher temperature tolerance, optional outlet-level control, full TAA compliance, and a longer standard warranty.
What the J90-2kLiD brings
- LiFePO₄ (LFP) chemistry with significantly longer service life
- Higher operating-temperature rating for hot IDF and edge spaces
- Faster battery recharge for improved availability after outages
- Optional outlet-level control with Web/SNMP
- Full TAA compliance for government and regulated procurement
- Longer standard warranty covering UPS and batteries

Choosing between them
The J90-2kLiD suits edge IT and network closets with limited cooling, high-reliability 1U deployments, sites needing fast recharge and long battery service life, distributed locations requiring remote outlet control, regulated procurement, and elevated-ambient environments.
Choose the J90-2kLiD if you need
- True online double-conversion protection
- Long-life LiFePO₄ batteries with minimal maintenance
- Operation up to 50 °C in hot edge or IDF environments
- Optional outlet-level control for remote sites
- TAA compliance and longer warranty coverage
The Smart-UPS Ultra SRTL2K2RM1UC may fit if you need
- Online protection with bundled network management
