Compatible Replacement Battery Kit

This kit provides a factory-fresh replacement battery cartridge designed for the Eaton-MGE Pulsar ESV3 UPS. It contains two 6V9A batteries assembled into a single cartridge for straightforward installation. The product is new and ready for immediate deployment in compatible power protection systems. It restores backup runtime without requiring modifications to the existing UPS unit.

Passive Operation and Low Heat Output

The sealed lead-acid batteries operate without active cooling, producing negligible noise during normal float charging and discharge cycles. Heat generation remains minimal under typical office or server-room ambient conditions. Power draw is limited to the UPS charging circuit maintaining the batteries at full capacity. No additional thermal management or acoustic planning is required for this replacement kit.

Questions about this item

How do I install the two 6 V 9 Ah batteries in my Eaton-MGE Pulsar ESV3 UPS and what step is most often missed?

Power off and unplug the UPS, open the front battery door, disconnect the old cartridge noting the red-to-red and black-to-black leads, insert the new cartridge with the same polarity, close the door, then power on and run a self-test — the step most often missed is forgetting the self-test so the UPS recalibrates its runtime estimate.

When will the 6 V 9 Ah batteries need replacing and how can I tell?

Expect 3–5 years of service; the UPS will signal replacement with a flashing battery LED and audible alarm, and runtime will drop noticeably during self-tests — replace both 6 V 9 Ah units at the same time to keep the string balanced.
