SKU CH-4AZX-CN3ZT

Two-pack of 12 V 12 Ah AGM batteries with F2 terminals, sized 151 × 98 × 95 mm and weighing 4.20 kg each, for Opti 1400ES UPS units

  • Reliable UPS backup with advanced AGM technology
  • Exact fit for Opti 1400ES with F2 terminals
  • Maintenance-free sealed lead-acid design
  • Two batteries included for extended runtime
  • 100% OEM replacement ensuring compatibility

Replacement Pair for Opti 1400ES UPS

This pack contains two 12V 12Ah sealed lead-acid batteries built with AGM technology. They are direct OEM replacements for the Opti 1400ES uninterruptible power supply. Each unit is maintenance-free and arrives ready to install. The pair restores backup runtime for critical power systems.

Suits UPS Maintenance; Not for Other Voltages

These cells suit technicians replacing depleted batteries in the Opti 1400ES or compatible UPS cabinets that accept F2 terminals. Buyers needing a different voltage, capacity, or terminal style should look at other listings. The two-pack format is intended for dual-battery compartments only.

F2 Terminals with 101 mm Total Height

The decisive specification is the F2 terminal type combined with a total height of 101 mm. Verify that the UPS chassis uses F2 connections and clears this height before ordering. Dimensions are 151 mm length, 98 mm width, and 95 mm container height. Each battery weighs approximately 4.20 kg.

Questions about this item

What comes in the box and do I need to buy terminals or cables separately?

The pack contains two sealed 12 V 12 Ah AGM batteries with F2 terminals already fitted; no extra terminals or cables are included.

Should I choose the 12 Ah version or a different capacity for the Opti 1400ES?

The Opti 1400ES is designed for 12 Ah batteries, so this 12 Ah two-pack is the correct match.

What does the 12 Ah rating mean once the batteries are installed in my UPS?

Each 12 Ah battery stores enough energy to deliver 12 amps for one hour at 12 V, giving the UPS its rated backup time.
