CyberPower RB1290X8 Replacement Battery Cartridge, 8 X 12 V / 9 Ah Sealed Lead-Acid Battery

The CyberPower RB1290X8 is a user-replaceable cartridge containing eight 12 V / 9 Ah sealed lead-acid batteries, designed for owners of compatible CyberPower OL8KRTHD or OL10KRTHD UPS systems who need a replacement battery assembly.

Recommended For

• IT and data-center teams restoring battery backup in a CyberPower OL8KRTHD or OL10KRTHD after the UPS reports weak or depleted internal batteries.
• Facilities or service technicians maintaining compatible rack or tower UPS installations that protect servers, workstations, NAS/storage, telecom, or networking equipment.
• Organizations seeking a pre-assembled, OEM-certified sealed lead-acid cartridge for a compatible UPS battery replacement, rather than sourcing and assembling individual cells.

Real-World Use Scenarios

• When an OL8KRTHD or OL10KRTHD reports weak or depleted batteries, replacing its compatible RB1290X8 cartridge restores the UPS battery system for outage backup; actual runtime depends on the UPS load and battery condition.
• For planned UPS maintenance in a server room or network closet, an IT team can keep the correct cartridge on hand and replace aging batteries before relying on the UPS for backup; confirm the required cartridge count for the specific UPS model.
• A qualified technician servicing an OL10KRTHD can use the compatible cartridge as part of a battery replacement, following the UPS service procedure to help maintain the system’s backup capability.
• After replacing a depleted cartridge, a business can continue using its compatible UPS to provide battery backup for connected critical equipment during power interruptions; the cartridge itself does not determine how long that equipment will run.
• When the old sealed lead-acid cartridge is removed, the owner can use the included recycling information and reusable packaging to send the expired batteries to an appropriate recycling center.
