HP/Compaq 242689-004 UPS Replacement Kit

This kit provides two 12V 18A sealed lead-acid batteries designed as a direct replacement for the HP/Compaq 242689-004 UPS cartridge. It restores backup power capacity for compatible uninterruptible power supply units. The package includes comprehensive installation instructions for straightforward user replacement. Condition is new and factory fresh.

Suits administrators maintaining specific

Ideal for IT staff replacing depleted batteries in the designated HP/Compaq UPS series to regain runtime protection. Not suitable for users whose UPS requires a different voltage, capacity or physical cartridge format. Buyers needing a single battery or a different ampere-hour rating should verify their unit specifications before purchasing.

Sustained discharge delivers rated capacity

The high-rate discharge cells are engineered to supply the rated 18A over the expected backup interval rather than only in short bursts. Internal resistance remains stable during extended power-out events, supporting consistent voltage to the inverter. Performance depends on the UPS load percentage and ambient temperature during the discharge cycle.

Questions about this item

Which UPS models accept the 242689-004 battery kit?

The kit replaces the HP Compaq 242689-004 cartridge; check your UPS documentation to confirm it uses two 12 V 18 Ah high-rate SLA batteries.

Can I mix these 12 V 18 Ah batteries with older 12 V cells still in the UPS?

All cells in a string must share the same capacity and age; replace the full set of four batteries at once to avoid imbalance and premature failure.

How do I verify the kit is working after installation?

Run a self-test from the UPS front panel or management software; a passed test and normal runtime during a simulated outage confirm correct operation.
