Replacement battery cartridges for legacy Powerware UPS — PW3110, PW5115, PW5125, PW9120, PW9125 series and equivalents. Powerware was acquired by Eaton in 2003; legacy units still in service use compatible aftermarket SLA cartridges from us.
Powerware was a major North American UPS manufacturer until Eaton acquired the company in 2003. Powerware-branded UPS — PW3110, PW5115, PW5125, PW9120, PW9125, and Plus, FERRUPS, and BladeUPS lines — remain in active service across Canadian sites in IT, telecom, industrial, and edge-compute deployments. The Powerware product portfolio was integrated into Eaton's catalog after acquisition; modern equivalents are the Eaton 5P, 5PX, 9SX, and 9PX families.
UPSPLUSBATTERY.CA stocks compatible aftermarket replacement cartridges for the legacy Powerware UPS line. For current-generation Eaton equivalents see Eaton UPS; for Eaton replacement batteries see Eaton replacement batteries; broader cross-brand catalog at all UPS replacement batteries.

Replacement cartridges UPSPLUSBATTERY.CA stocks for legacy Powerware are compatible aftermarket — built to identical V, Ah, terminal, and connector spec as factory cells, using reputable SLA brands (CSB, Yuasa, BB Battery, Panasonic).

Side or rear of the Powerware UPS lists model number and (on most models) battery configuration.

SLA: 3–5 years rated in 20–25 °C climate-controlled environment. Most legacy Powerware UPS predate modern impedance-based battery monitoring — schedule routine load tests every 2–3 years on aging units.
Most Powerware UPS use front-access or side-access cartridges. PW5115 / PW9120: front-access, typically requires brief load transfer to bypass. PW5125 / PW9125: front-access, hot-swappable on most SKUs. How to install UPS battery.

No. Eaton acquired Powerware in 2003 and rebranded the catalog. Modern equivalents: PW5115 → Eaton 5E / 5P, PW9120 → Eaton 9SX / 9PX, BladeUPS → 93PM modular.
For most pre-2010 SKUs, no. Aftermarket built to factory spec is the practical replacement.
Yes — same V, Ah, terminal, connector spec. Equivalent performance and life.
Powerware electronics from the 2000s typically have 15+ years of design life. If the UPS still passes self-test and load test, replacing the battery is far cheaper than a new UPS.
PW9120 batteries vary by VA — 700 VA uses 24 V (2 cells), 1500 VA uses 48 V (4 cells), 2000 VA uses 48 V or 72 V depending on revision. Send the model number for verified cross-reference.
1-year UPSPLUSBATTERY full-replacement on aftermarket cartridges.
