Eaton PW3115-300 compatible battery kit

This replacement battery kit provides a single 12V 7A sealed lead-acid cell built for the Powerware PW3115-300 UPS. It restores backup power for critical servers and network gear when the original cells reach end of life. The kit arrives factory fresh with comprehensive installation instructions included. System administrators can swap the cartridge without specialised tools.

Maintenance profile and power behaviour

The high-rate discharge chemistry delivers the instantaneous current a UPS demands during a mains failure. Under normal float charging the cell runs cool and silent, adding negligible heat to the rack environment. Self-discharge is low so the reserve stays ready during extended periods without outages. No active cooling or additional power draw is introduced by the replacement.

Integration into a rack build

The cartridge matches the original form factor so it slides into the existing battery compartment without chassis modifications. One unit replaces the single battery module used in the PW3115-300, freeing no extra bays but also requiring no extra space. Installers should verify the UPS model number before ordering to ensure correct fit. No firmware updates or configuration changes are needed after installation.

Questions about this item

How do I install the 12V 7A battery in my PW3115-300 UPS and what step is often missed?

Power down and unplug the UPS, open the battery compartment, disconnect the old battery terminals noting polarity, connect the new 12V 7A battery matching red to positive and black to negative, secure the compartment, then power on and run a self-test to confirm the replacement is recognised.

What maintenance or replacement will the 12V 7A SLA battery need over its service life?

The sealed lead-acid battery requires no watering or electrolyte checks; plan to replace the 12V 7A unit every three to five years or when the UPS reports reduced runtime or a battery fault during self-test.

What limit appears first when the PW3115-300 UPS runs on this 12V 7A battery under sustained load?

Runtime is the first constraint; the single 12V 7A high-rate discharge cell provides limited ampere-hours, so extended outages will deplete the battery before thermal or voltage limits are reached.
