APC by Schneider Electric SRT2200XLA vs CyberPower OL2200RTXL2U: Specification Comparison
Both units are 2200VA / 1800W double-conversion online UPS systems designed for small-to-medium IT loads requiring true sine-wave output and zero-transfer-time battery backup. The APC SRT2200XLA ships as a tower-only chassis, while the CyberPower OL2200RTXL2U is a 2U rack/tower convertible. This comparison evaluates the three dimensions installers and IT buyers care about most: runtime and battery expandability, physical form factor and environmental ratings, and connectivity plus management options.

How do runtime, battery capacity, and expandability compare between the SRT2200XLA and OL2200RTXL2U?
The APC SRT2200XLA ships with a 72V / 306 VAh internal battery pack and does not specify runtime minutes in the provided specs. It supports up to 10 external SRT72BP battery packs, scaling VAh from 918 (1 pack) to 6,426 (10 packs), giving it a well-documented runtime-extension ladder. Battery recharge time is rated at 3 hours. Battery life expectancy is listed as 3–5 years, and the replacement cartridge is APCRBC141 / SRT72RMBPUS.
The CyberPower OL2200RTXL2U specifies runtime directly: 8 minutes at full load (1800W) and 21 minutes at half load (900W), powered by six internal 12V/9Ah sealed lead-acid cells (72V equivalent string). It also supports up to 10 external battery modules. Battery cells are hot-swappable and user-replaceable without powering down the load — a distinction not claimed for the SRT2200XLA in the provided specs.
The SRT2200XLA's internal VAh (306 VAh at 72V) is substantially larger than the OL2200RTXL2U's internal string (6 × 9Ah = 54Ah × 12V = 648 VAh at the cell level, but the UPS DC bus voltage determines usable runtime — CyberPower does not publish internal VAh directly, only runtime minutes). Buyers who need hard runtime numbers at commissioning time have them only for the CyberPower unit.
Which unit better suits rack environments, and how do their physical and environmental specs differ?
The APC SRT2200XLA is explicitly tower-only: its specs state 'Not rack-mountable,' mounting position 'Vertical,' and 'Two Post Mountable: 0.' Dimensions are listed only as 17.01 in (43.2 cm) — a single-axis figure — and weight is 55.12 lb (25 kg). Its IP rating is IP20 (finger-protected, not dust- or splash-rated). Operating altitude reaches 10,000 ft and storage altitude 50,000 ft. Storage temperature is listed as 5–113°F (−15 to 45°C), but operating temperature is not specified in the provided data.
The CyberPower OL2200RTXL2U is a 2U rack/tower convertible (432 × 89 × 600 mm / 17 × 3.5 × 23.62 in) with mounting hardware included. It weighs 68.2 lb (30.93 kg) — 13 lb heavier. Operating temperature is specified as 32–104°F (0–40°C). No IP rating or altitude spec is provided in the CyberPower data.
For any installation in a standard 19-inch equipment rack, only the OL2200RTXL2U is an option from the specs as provided. The SRT2200XLA requires dedicated floor or shelf space. Heat dissipation is documented only for the APC unit: 535 Btu/h — useful for data-center thermal planning. Neither spec sheet supplies noise (dBA) figures.
What connectivity and remote-management capabilities do each unit provide out of the box and via options?
The APC SRT2200XLA ships with one free expansion slot and supports APC Network Management Card 2 or 3 with environmental monitoring as an optional add-on. No USB or serial interface is mentioned in the provided specs. Alarms are described as 'audible and visible, prioritized by severity.' The unit has one power module slot with 1,400 noted under 'Number of Power Module' — the exact function of this figure is ambiguous in the spec data provided.
The CyberPower OL2200RTXL2U includes USB (HID) and RS-232 serial interfaces in the base unit, enabling immediate connection to a host or network-attached management server without additional cards. An optional RMCARD205 network management card adds SNMP/Web/Telnet remote monitoring. Compliance certifications — UL1778, CSA C22.2 No.107.3, FCC Part 15 Class A, RoHS — are explicitly listed; APC's certifications are not enumerated in the provided spec data.
Out-of-the-box, the OL2200RTXL2U offers richer native connectivity (USB + serial vs. no wired interface stated for the SRT2200XLA). Both units require an optional network card for full SNMP/remote management. The CyberPower unit also carries a $400,000 lifetime connected-equipment guarantee; no equivalent guarantee is mentioned in APC's provided specifications.
Which should you choose: the SRT2200XLA or the OL2200RTXL2U?
Our take: The OL2200RTXL2U is the stronger choice when the installation is rack-based and native USB/serial connectivity matters at commissioning. It occupies 2U in a standard 19-inch rack — the SRT2200XLA is explicitly not rack-mountable — and ships with USB HID and RS-232 serial interfaces without optional cards, while APC's provided specs list no wired interface in the base unit. The OL2200RTXL2U also publishes concrete runtime figures (8 min full load / 21 min half load) and specifies hot-swappable, user-replaceable battery cells, supporting maintenance without load shutdown. Conversely, the SRT2200XLA is the stronger choice for floor/tower deployments where a larger, more granular battery-extension ladder is required: its published expansion path scales from 306 VAh to 6,426 VAh across ten external packs with explicit VAh figures at each step; CyberPower's expansion VAh per external module is not stated in the provided specs. APC also documents heat dissipation (535 Btu/h) and a 10,000 ft operating altitude, useful for thermal and elevation-sensitive sites.

Frequently Asked Questions
Which should you choose: the SRT2200XLA or the OL2200RTXL2U?
The OL2200RTXL2U is the stronger choice when the installation is rack-based and native USB/serial connectivity matters at commissioning. It occupies 2U in a standard 19-inch rack — the SRT2200XLA is explicitly not rack-mountable — and ships with USB HID and RS-232 serial interfaces without optional cards, while APC's provided specs list no wired interface in the base unit. The OL2200RTXL2U also publishes concrete runtime figures (8 min full load / 21 min half load) and specifies hot-swappable, user-replaceable battery cells, supporting maintenance without load shutdown. Conversely, the SRT2200XLA is the stronger choice for floor/tower deployments where a larger, more granular battery-extension ladder is required: its published expansion path scales from 306 VAh to 6,426 VAh across ten external packs with explicit VAh figures at each step; CyberPower's expansion VAh per external module is not stated in the provided specs. APC also documents heat dissipation (535 Btu/h) and a 10,000 ft operating altitude, useful for thermal and elevation-sensitive sites.
Can the SRT2200XLA or OL2200RTXL2U be mounted in a standard 19-inch equipment rack?
Only the OL2200RTXL2U supports rack mounting. Its specs confirm a 2U rack/tower form factor (432 × 89 × 600 mm) with mounting hardware included. The SRT2200XLA specs explicitly state 'Not rack-mountable' and 'Mounting Position: Vertical,' making it a tower-only unit.
Which UPS makes battery replacement easier — the SRT2200XLA or the OL2200RTXL2U?
The OL2200RTXL2U specifies hot-swappable, user-replaceable battery cells (6 × 12V/9Ah), meaning batteries can be changed without shutting down the connected load. The SRT2200XLA identifies replacement cartridges (APCRBC141 / SRT72RMBPUS) but does not describe hot-swap capability in the provided specifications.
Is the SRT2200XLA or OL2200RTXL2U better for sites that need to scale runtime significantly over time?
The SRT2200XLA publishes an explicit VAh figure for each of its ten external battery pack options, ranging from 918 VAh (1 pack) to 6,426 VAh (10 packs), giving precise runtime planning data at every expansion step. The OL2200RTXL2U also supports up to 10 external modules, but the provided specs do not list VAh capacity per external module — only the base runtime (8 min full / 21 min half load) is documented.
