Compatible UPS Replacement Kit

This replacement battery kit provides a 12 V high-rate discharge SLA unit rated at 45 W. It is designed for users who need a direct swap for a Yuasa NPW45-12 cartridge in an existing uninterruptible power supply. The package includes installation instructions for straightforward fitting.

Single 12 V 9 Ah SLA Cell

The kit contains one sealed lead-acid battery delivering 12 volts and 9 ampere-hours. This capacity and chemistry determine whether the unit matches the original equipment specification and runtime requirements of the UPS. Verify the host device calls for a 12 V 9 Ah high-rate cell before ordering.

Sealed Maintenance-Free Operation

The valve-regulated lead-acid construction requires no watering and emits negligible gas during normal float charging. Internal resistance stays low under typical UPS duty cycles, so heat rise remains modest and acoustic noise is absent. The sealed case prevents electrolyte leakage in any mounting orientation.
