Panamax BATT1500-EXT Battery Extension Pack For F1500-UPS and MB1500

Product Overview

The Panamax battery extension pack BATT1500-EXT extends the battery backup runtime of the Panamax MB1500 and F1500-UPS by as much as 4x, making it the correct accessory for commercial AV installations where longer outage coverage is required. Designed as a plug-and-play addition to the existing UPS, the BATT1500-EXT uses heavy-gauge DC connectors and a matched form factor to integrate cleanly into rack or tower deployments. It is the direct solution for AV integrators who have specified the MB1500 for a rack mount UPS AV equipment installation and need to extend runtime for projectors, processors, amplifiers, or network gear beyond what the built-in battery supports. The BATT1500-EXT supports hot-swap battery replacement to minimize maintenance downtime.

Product Description

The BATT1500-EXT contains eight 12V / 9Ah sealed lead-acid batteries arranged in two strings of four cells in series. This configuration matches the internal battery bus of the Panamax MB1500 and Furman F1500-UPS, allowing the extension pack to increase total battery capacity proportionally and extend backup runtime by up to four times compared to the UPS operating on its internal battery alone. The practical impact is significant: an MB1500 that provides 12 minutes at full load or 32 minutes at half load can deliver substantially longer coverage when the BATT1500-EXT is added — supporting proper equipment shutdown sequences, in-progress recordings, or uninterrupted AV delivery through extended outage events.

The 2U metal enclosure matches the visual profile of the MB1500 and can be rack-mounted in a standard 19-inch equipment rack directly adjacent to the UPS, or configured for tower installation. The heavy-gauge power cord uses plug-and-play DC connectors that mate directly to the MB1500's battery extension port without requiring any tools or internal modifications. A front-panel power on/off switch provides a local manual reset and control point, and a user-accessible rear-panel fuse simplifies maintenance. The rigid all-metal construction is appropriate for demanding commercial environments where rack equipment is subject to vibration, temperature variation, or high-density installation.

Battery replacement is user-serviceable: the BATT1500-EXT is designed for hot-swap replacement using BB Battery HR9-12 cells, and batteries charge in approximately 8 hours after a full discharge. Operating temperature range is 32°F to 95°F (0°C to 40°C), suitable for conditioned equipment rooms. The unit is ROHS compliant and carries UL1778 and cUL 107.1 certification. The 3-year product warranty and 2-year battery warranty match those of the MB1500 UPS, ensuring consistent coverage across the combined system.
