Compatible UPS battery kit

The RefurbUPS Conext 900 CNB900 kit provides a direct replacement battery for compatible uninterruptible power supply units. It contains a single 12V 12A sealed lead-acid cell rated for high-rate discharge. The kit is intended for users maintaining existing UPS hardware that accepts this specific cartridge format.

12V 12A high-rate discharge cell

The deciding specification is the 12V 12A sealed lead-acid battery built for high-rate discharge performance. This electrical profile must match the original equipment requirement exactly for the UPS to function correctly. Verify that your unit specifies a 12V 12A cartridge before ordering.

Straightforward cartridge swap

Installation involves removing the old cartridge and inserting the new one following the included instructions. The process is designed for tool-free access on compatible models. The most common issue is ordering the wrong voltage or ampere-hour rating, so confirm the label on your existing battery matches 12V 12A before purchase.

Questions about this item

What does the 12 V 12 Ah rating mean once the battery is installed in my UPS?

The 12 V 12 Ah rating shows the pack delivers 12 volts and can supply 12 ampere-hours, giving the UPS its rated backup time when mains power fails.

What connection standard does the CNB900 kit use to link with the UPS?

The kit uses the standard F2 faston terminals that match the original APC CNB900 cartridge, so it plugs straight into the UPS battery compartment.

Will the 10 kg kit fit inside my existing Conext 900 UPS chassis?

Yes, the single 12 V 12 Ah block matches the original cartridge dimensions, so it slides into the same battery bay without modification.
