J90i-3kLiD vs APC SRT3000RMXLI
The Xtreme Power J90i-3kLiD is a 1U online double-conversion lithium UPS for 208/230 V edge and telecom infrastructure. The APC SRT3000RMXLI is an online double-conversion VRLA UPS in 2U, now discontinued. Both are online and 3000 VA / 2700 W; the J90i differentiates on LFP battery life, efficiency, recharge, rack density, temperature, TAA, and warranty, and serves as a modern replacement for aging SRT systems.
What the J90i-3kLiD brings
- LiFePO₄ batteries, up to 15-year life vs 3–5
- 1U vs 2U (higher rack density)
- Faster recharge (1 hour vs 3)
- Per-outlet control, 50 °C operation
- TAA compliance and a 6-year warranty
Side-by-side specifications
| Specification | Xtreme Power J90i-3kLiD | APC SRT3000RMXLI | Advantage / consideration |
|---|---|---|---|
| Topology | Online double conversion | Online double conversion | Equivalent protection |
| Battery chemistry | Lithium iron phosphate (LFP) | VRLA lead-acid | J90i – longer service life |
| Battery life | Up to 15 yr / 3,000–5,000 cycles | 3–5 yr typical | J90i – far fewer replacements |
| Capacity | 3000 VA / 2700 W | 3000 VA / 2700 W | Comparable output |
| Efficiency | 92% | 91% | J90i – higher efficiency |
| Battery runtime | 6 min @ 2700 W | 5 min @ 2700 W | Comparable runtime |
| Recharge time | 1 hour | 3 hours | J90i – faster recovery |
| Outlet control | Individually controllable (Web/SNMP) | Load segments | J90i – per-outlet remote reboot |
| Rack height | 1U | 2U | J90i – higher rack density |
| Operating temperature | Up to 50 °C (122 °F) | Up to 40 °C (104 °F) | J90i – rated to 50 °C |
| TAA compliance | Yes | No | J90i – federal procurement eligible |
| Warranty | 6-year UPS & battery | 3-year limited | J90i – longer coverage |
Specifications based on publicly available manufacturer documentation; confirm against current vendor data. The APC SRT3000RMXLI is discontinued; the J90i is positioned as a modern lithium replacement.
Choosing between them
Both are online double-conversion. The J90i-3kLiD leads on LFP battery life, efficiency, recharge, rack density, temperature, TAA, and warranty, and is a current-production replacement for the discontinued SRT3000RMXLI. Capacity and runtime are comparable.
Choose the J90i-3kLiD if you need
- A current-production replacement for aging SRT systems
- Long-life LiFePO₄ batteries with fewer replacements
- 1U rack density and 50 °C operation
- Per-outlet control for remote reboot
- TAA compliance and a 6-year warranty
The APC SRT3000RMXLI context
- It is discontinued; new deployments should evaluate current platforms
- Existing SRT installations may standardize on APC for spares
- Sites with established VRLA maintenance programs
Frequently asked questions
It is discontinued. Organizations running SRT3000RMXLI systems typically evaluate current lithium platforms such as the J90i-3kLiD when batteries reach end of life, since the J90i preserves the online topology while adding LFP service life and 1U density.
Yes. Unlike APC’s line-interactive SMT series, the SRT3000RMXLI is online double-conversion, as is the J90i. The differences are battery chemistry, rack height, recharge time, temperature, TAA, and warranty rather than topology.
Yes, the J90i is TAA compliant for U.S. federal and regulated procurement; the SRT3000RMXLI is not.
The J90i is 1U versus the SRT’s 2U, halving the rack height for the same 3000 VA / 2700 W output, which matters in dense network and telecom racks.
