12 V 3.3 Ah AGM UPS Battery

This 12 V 3.3 Ah sealed lead-acid battery uses AGM technology for maintenance-free operation. It serves as a direct OEM replacement for compatible UPS units and backup power systems. The compact design fits a range of APC and CyberPower models listed in the specifications.

Drop-in replacement with terminal spacing of 1.6

Installation is a simple swap: remove the old pack, connect the existing leads to the matching terminals and secure the battery in the same cavity. The 1.6 inch terminal distance matches the original equipment, so no adapter cables or modifications are required. Verify polarity before tightening the connections to avoid a reversed hookup.

Ideal for APC BE325, BE350

Buyers needing a higher capacity pack or a lithium chemistry should look elsewhere, as this unit is fixed at 3.3 Ah and uses AGM construction. It is not suited for applications that demand longer runtime than the rated capacity provides.

Questions about this item

How can I confirm the 12V 3.3AH battery is working after installing it in my UPS?

After installation, power on the UPS and let it charge for the recommended period. Then run a self-test or briefly pull the mains plug to verify the unit stays on and the battery voltage holds near 12V under load.

What comes in the box and what must I buy separately for the WP3-12 replacement?

The box contains the 12V 3.3AH AGM battery with F1 terminals spaced 1.6 inches apart. You may need to reuse the existing cable harness or connector from the old battery if it is not included with this unit.

Which capacity should I choose among the listed compatible models like the 325, 350 and 300SL units?

All listed models — BE325, BE350, CPS300SL, CPS325SL and the RBC35 cartridge — use the same 12V 3.3AH specification. Choose the one that matches your UPS model number exactly.
