GreenTech 24V 9Ah SLA Battery Cartridge

This replacement battery cartridge delivers 24 volts and 9 amp-hours using two 12V 9Ah cells with F2/T2 terminals. It is built as a compatible alternative to the APC APCRBC124 and APCRBC123 cartridges. The unit arrives tested, charged and ready to install in supported APC uninterruptible power supplies.

Replaces APC RBC124 and RBC123 Cartridges

The cartridge fits a wide range of APC UPS models including BR, BX, BN, SMC and SMT series units listed in the compatibility data. It is a direct swap when the original RBC124 or RBC123 cartridge reaches end of life. The jump is worth it when the UPS reports a battery fault or runtime has dropped below acceptable levels.

Physical Limits of the 6 x 8 x 3 Inch Form Factor

The cartridge measures 6.00 by 8.00 by 3.00 inches and weighs 10 lb, so the UPS battery compartment must accommodate those exact dimensions. The 24V 9Ah capacity is fixed by the two-cell 12V 9Ah construction and cannot be increased within this housing. Buyers needing longer runtime must select a higher-capacity UPS rather than a larger cartridge.

Questions about this item

Will the 6.00" x 8.00" x 3.00" cartridge fit my SMT750RM2U rack-mount UPS?

Yes, those dimensions match the OEM RBC124 cartridge used in the SMT750RM2U and all other listed APC models.

What is the most common mistake when installing this 24 V 9 Ah cartridge?

Forgetting to reconnect the internal Anderson-style jumper between the two 12 V cells, leaving the UPS with only 12 V and no runtime.

How often should I replace the two 12 V 9 Ah F2 cells inside this cartridge?

Plan on a 3-to-5-year cycle; swap them when the UPS self-test fails or reported runtime falls to roughly half of the original 9 Ah capacity.
