What about HP / Compaq UPS?

HP (Hewlett-Packard) sold a range of UPS systems under the HP and Compaq brands for the SMB and enterprise server-room market through the mid-2000s and into the early-to-mid 2010s, when HP exited the UPS category. The HP UPS line included R-series rack-mount (R1500, R3000, R5500, R12000XR3) and T-series tower units. Many of these UPS remain in active service in Canadian server rooms and require replacement battery cartridges that are no longer manufactured by HP. Compatible aftermarket cartridges built to factory V, Ah, and connector spec are the practical replacement.

UPSPLUSBATTERY.CA stocks compatible aftermarket cartridges for the HP / Compaq UPS line. Full UPS battery catalog at all UPS replacement batteries.

Aftermarket disclosure

Replacement cartridges UPSPLUSBATTERY.CA stocks for HP / Compaq are compatible aftermarket — built to identical V, Ah, terminal, and connector spec as factory cells, using reputable SLA brands (CSB, Yuasa, BB Battery, Panasonic). They are not OEM HP / HPE / Compaq parts. 1-year UPSPLUSBATTERY full-replacement warranty.

HP exited UPS in the mid-2010s — OEM cartridges for the HP UPS line are no longer manufactured. Aftermarket built to factory spec is the only practical replacement option.

How to identify the right cartridge

Method 1: unit label

Side or rear of the HP UPS lists model number, battery configuration (cells, voltage, Ah), and on some models the underlying OEM (APC or Eaton).

Method 2: existing cartridge

Open the front bezel — cartridge label lists cell count, voltage, and Ah. Many R-series use 12 V SLA cells in 24 V or 48 V strings.

Method 3: model-number lookup

Send the HP UPS model number to our team — replies within 1 business day with verified cross-reference.

How long do HP UPS batteries last?

SLA: 3–5 years rated in 20–25 °C climate-controlled environment. Most legacy HP UPS predate modern impedance-based battery monitoring — schedule routine load tests every 2–3 years on aging units.

How to replace

Most HP R-series and T-series use front-access cartridges. Hot-swappable on most current-revision SKUs. For multi-cell strings, qualified service may be appropriate due to string voltage. How to install UPS battery.

FAQ

Is HP still making UPS?

No — HP exited the UPS category in the mid-2010s. Currently-deployed HP UPS units are out of factory production and OEM cartridges are discontinued.

Can I still get OEM HP replacement batteries?

Generally no for pre-2010 SKUs. Some Hewlett Packard Enterprise server-line battery accessories remain available through HPE channels — contact our team to check.

Will aftermarket work in my HP R-series?

Yes — same V, Ah, terminal, connector spec as factory.

How do I identify the underlying OEM (APC or Eaton)?

Check the unit label — many HP UPS list the original OEM. Alternatively, the chassis design / outlet pattern often matches the donor APC or Eaton model. Send the HP model number to our team and we'll cross-reference.

Should I keep the HP UPS or replace it?

HP UPS electronics from the 2000s typically have 15+ years of design life. If the UPS still passes self-test, replacing the battery is far cheaper than a new UPS. If electronics show signs of failure, step up to a current APC, Eaton, or Tripp Lite equivalent.
