Compatible UPS replacement kit

This kit provides a direct replacement battery cartridge for UPS units that use the Yuasa NPW45-6 form factor. It contains a single high-rate discharge 6V9A sealed lead-acid battery. The package is designed for users who need to restore backup power to their existing UPS hardware.

Capacity and runtime headroom

The 6V9A battery delivers the rated capacity required for standard UPS load profiles. It handles typical server and network equipment loads during short outages. Runtime decreases under heavier connected loads or when the battery ages beyond its design life.

Thermals noise and power draw

Sealed lead-acid chemistry operates silently with no moving parts during discharge or recharge. Heat output remains low under normal float charging conditions. The battery draws only the trickle current needed to maintain full charge while the UPS is on mains power.

Questions about this item

Will this 6V9A Yuasa NPW45-6 compatible battery work in my older UPS that used the same model number?

The kit contains one 6V9A SLA battery built as a direct Yuasa NPW45-6 compatible replacement, so it fits the same form factor and voltage requirements as the original unit.

How can I verify the replacement battery is operating correctly once installed?

Run the UPS self-test after installation; a successful test and normal runtime under load confirm the 6V9A high-rate discharge cell is performing as intended.

Does the box include mounting hardware or cables, or must I purchase them separately?

The package supplies the battery cartridge plus comprehensive installation instructions; no extra hardware or cables are included, so reuse the existing connectors from the old battery.
