UPS Replacement Kit for Ablerex AS2K

This kit provides four 12 V 7 A sealed lead-acid batteries designed as a direct replacement for the Ablerex AS2K uninterruptible power supply. It is intended for system administrators and facility managers who need to restore backup runtime on an existing AS2K unit. The package arrives factory-fresh and includes step-by-step installation instructions.

Four 12 V 7 A High-Rate Discharge Cells

The defining specification is the quartet of 12-volt, 7-ampere-hour high-rate discharge SLA cells that match the original AS2K cartridge voltage and capacity. Using the correct high-rate chemistry ensures the UPS can deliver its rated load during a power event without premature voltage sag. Substituting standard cyclic SLA batteries would compromise hold-up time and could trip the inverter.

Installation Instructions Included

The bundled printed guide walks through safe removal of the spent cartridge, proper orientation of the new cells, and reconnection of the terminal harness. Following the supplied procedure reduces the risk of short circuits or reversed polarity during the swap. No additional tools, firmware updates or configuration software are required to complete the replacement.

Questions about this item

What does the 12 V 7 A rating mean for my UPS runtime?

Each 12 V 7 A battery in the kit delivers high-rate discharge current to support the Ablerex AS2K UPS during a power outage. The four-unit configuration matches the original cartridge voltage and capacity, so the UPS can maintain its designed backup time without modification.

Which battery interface does this kit use to connect inside the AS2K?

The batteries are standard sealed lead-acid blocks with F2 faston terminals. They slide into the existing AS2K battery tray and plug directly into the UPS internal wiring harness, requiring no adapters or soldering.

What physical space and mounting does the four-battery kit need?

The kit weighs 24 and contains four individual 12 V 7 A SLA blocks sized to fit the factory AS2K battery compartment. No extra brackets or rails are required; the units sit in the original tray and secure with the UPS cover.
