Columbia Siat GT-One 14.4V Replacement Battery 85073091

Columbia Siat GT-One / GT-H / Smart LXT — 14.4V Li-ion Replacement Battery (85073091)

This is a 14.4V, 3000mAh Li-ion replacement battery for the Columbia Siat GT-One, GT-H, Smart LXT 10-16, and Power HP 19-25 strapping tools. It replaces OEM part number 85073091. The pack restores full tensioning and sealing operation on compatible cordless strapping equipment used in packaging and materials handling.

• GT-One, GT-H, Smart LXT, and Power HP compatibility: These models share the same 14.4V battery platform, connector housing, and BMS handshake protocol. One pack works across the full range without modification.
• Bench tested on actual hardware: We cycled this pack through repeated tensioning loads on a GT-One and monitored BMS behaviour at peak motor draw. The protection circuit handled the current spike at maximum tension without nuisance tripping.
• Cold warehouse use: If the tool is stored or transported below 10°C, bring the battery above that temperature before starting work. The tensioning motor draws a sharp current peak at maximum load — a cold cell can hit the BMS low-voltage threshold on that spike and cut out mid-cycle.

BMS cutoff during the tensioning cycle on a new pack

The GT-One motor pulls its highest current in the final phase of tensioning, just before the seal fires. A new pack that has been sitting in storage at partial charge may have cells below the BMS's acceptable working voltage under that load. The protection circuit reads the voltage sag as a fault condition and cuts the output. Fully charge the pack before first use — the BMS re-evaluates cell state on the next trigger and typically clears the fault at 16.4V measured at the pack terminals.

Charger shows a fault light on a replacement pack after long storage

Li-ion cells self-discharge during transit and storage. If the pack voltage has dropped below approximately 10V, most OEM Siat chargers will reject it as a safety measure and show a red or flashing fault indicator. Remove the pack, wait 30 seconds, and reinsert it — some chargers will attempt a recovery charge on the second insertion. If the fault persists, check pack voltage at the contacts with a multimeter; anything above 9V is typically recoverable by holding the pack in the charger for a full 60-minute cycle before the charger switches to normal mode.
