Key Features

• Dual 12V / 9Ah Sealed Lead-Acid Cells: Two cells wired in series deliver the voltage and capacity profile the host UPS expects. At 9Ah each, you recover the original runtime the UPS was spec'd for — running a depleted OEM battery at 30–50% of rated capacity is the leading cause of unexpected shutdowns during power events.
• Sealed Lead-Acid (SLA) Chemistry: SLA cells require no electrolyte maintenance, don't off-gas under normal charge conditions, and are safe for installation inside enclosed UPS cabinets. No venting cutouts or special enclosure modifications needed.
• Plug-and-Play Connector: The terminal uses the same connector format as the original factory battery. No wire splicing, no crimping — disconnect the old pack, connect the new one, close the panel. Reduces battery swap time to minutes and eliminates wiring errors that can damage the UPS charging circuit.
• Compact 7.8
