TAA-Compliant 12 V Lead-Acid UPS Battery

This 12 V four-cell lead-acid battery carries TAA compliance and is built as a direct replacement for compatible uninterruptible power supply units. It restores backup runtime for critical network and server equipment when the original cells reach end of life.

Suits owners of listed SU

Buyers who need a different voltage, a higher capacity, or a lithium-based chemistry should look at other options. The pack is not designed for non-UPS applications or for units outside the specified compatibility list.

Simple slide-in replacement for supported UPS

Installation typically involves powering down the UPS, opening the battery door, disconnecting the old pack, and inserting the new one. The most common issue is forgetting to reconnect the internal wiring harness before closing the door.
