Replacement battery kit for UPS units

This kit supplies a single 12V 18A sealed lead-acid battery built to the Genesis series specification. It arrives factory-fresh and includes step-by-step installation instructions so technicians can swap the cartridge without guesswork.

Swaps out depleted 12V 18A cartridges

The upgrade is worthwhile when runtime has fallen below acceptable levels or when the original pack shows swelling or voltage sag under load. A fresh cell restores the full rated capacity the unit was designed to deliver.

Delivers steady high-rate discharge during

The SLA chemistry maintains stable voltage throughout the discharge curve rather than collapsing after a brief burst. At 15 weight units the pack remains manageable for rack or tower installations while sustaining critical loads until utility power returns.

Questions about this item

Will the 12V 18A battery fit the existing UPS compartment?

The kit contains one 12V 18A SLA battery built to match the EnerSys NP18-12 form factor, so it fits the same compartment as the original cartridge.

Which step in the included instructions do installers most often miss?

Users frequently forget to torque the terminal bolts to the specified value after connecting the leads, leaving a loose connection that causes alarms.

How often should the 12V 18A SLA battery be replaced?

Plan on swapping the battery every three to five years; high-rate discharge cells degrade faster under frequent deep cycles.
