Kit contents

This replacement kit contains two sealed lead-acid batteries rated at 6 volts and 4.5 ampere-hours each. They are designed to fit the Eaton Powerware PW3110-300VA uninterruptible power supply. The pack arrives factory-fresh and ready for immediate installation.

Installation support

Comprehensive replacement instructions are included so that the battery swap can be completed without specialist tools. Plug-and-play readiness means the UPS recognises the new cells as soon as they are connected, restoring runtime without firmware updates or configuration steps.

Capacity limit

The 300 VA rating defines the maximum load the UPS can support while these batteries are installed. Equipment drawing more apparent power will exceed the unit’s capability regardless of battery condition. Runtime at full load is determined by the 4.5 Ah capacity and cannot be extended without a higher-rated UPS model.

Questions about this item

How often do the two 6V 4.5A SLA batteries in this PW3110-300VA kit need replacing?

Sealed lead-acid batteries typically last three to five years; plan replacement when runtime drops noticeably or the UPS signals a battery fault.

What limits runtime during a long outage on the PW3110-300VA?

The 4.5Ah capacity of each 6V cell sets the total energy available, so runtime ends when that stored charge is depleted.

How much heat do the 6V 4.5A batteries generate while the UPS runs continuously?

Normal float charging produces only modest warmth; ensure the UPS vents stay clear so heat dissipates without fan noise increasing.
