BatteryJack inc. 12V 3.3AH AGM UPS Battery WP3-12

SKU CH-44H0-GGWDN

12 V 3.3 Ah AGM battery fits APC, CyberPower and RBC UPS cartridges with 1.6 in terminal spacing

  • Maintenance-free AGM design eliminates fluid checks
  • 12V 3.3AH capacity powers compatible UPS units
  • 100% OEM replacement fits APC RBC35 and CyberPower models
  • Compact 5.28 x 2.64 x 2.4 inch size suits tight enclosures
  • Expected 4-7 year service life reduces replacement frequency

Purpose & Audience

This 12 Volt 3.3 AH AGM battery is a direct replacement for UPS units and backup power systems. It suits technicians and facility managers who need a maintenance-free sealed lead-acid cell for emergency lighting, security panels or telecom equipment.

Decisive Specification

The critical match is the 1.6 inch terminal spacing combined with the 5.28 by 2.64 by 2.4 inch case dimensions. If the existing battery tray or connector lead layout differs from these measurements the unit will not fit or connect correctly.

Build Integration

The battery slides into standard UPS cartridge slots such as the RBC35 or RBC47 form factor and powers models including the BE325, BE350 and CPS325 series. Its sealed AGM construction allows any orientation mounting and eliminates the need for separate ventilation or electrolyte checks.

Questions about this item

How much runtime does the 3.3 AH capacity actually give inside a UPS?

The 3.3 AH rating means the battery can supply 3.3 amps for one hour at 12 volts; actual runtime depends on the UPS load and efficiency.

What terminal spacing does the 1.6 inch measurement refer to and will it match my unit?

The 1.6 inch figure is the centre-to-centre distance between the two F1/F2 faston terminals; check your existing battery for the same spacing before ordering.

Will the 5.28 by 2.64 by 2.4 inch case fit in my APC BE350G battery compartment?

Those are the external length, width and height dimensions; the BE350G is listed as a compatible model so the case should fit the compartment.
