Compatible EXFO battery

This Centenex Electronics lithium-ion pack replaces the original power source for EXFO FTB-1, FTB-200, MAX-700, MAX-710B and MAX-730 test instruments. It matches part numbers FTB-1LO4D318A, LO4D318A and XW-EX009. The black housing fits the existing battery bay without modification. Field technicians can swap it in seconds during on-site maintenance.

14.4 V 2.6 Ah capacity

The cell delivers 14.4 volts and 2.6 ampere-hours for 37.44 watt-hours of energy. That rating determines whether the pack sustains a full testing shift on a single charge. Lower-capacity alternatives would require more frequent swaps or tethered operation. The lithium-ion chemistry holds charge during storage between jobs.

Fits FTB and MAX chassis

The pack slides into the standard battery compartment on supported EXFO handheld analysers. No adapter plate or firmware update is needed. Its 148.96 by 41.00 by 23.20 millimetre footprint matches the original envelope. Users gain a fresh power source while keeping the instrument’s original form factor and balance.

Questions about this item

What does the 37.44 Wh rating mean for actual run time in an EXFO FTB-200?

The 37.44 Wh capacity at 14.4 V delivers 2.6 Ah, so run time depends on the instrument's average draw — lower draw extends use proportionally.

How does the 14.4 V output match the charging and power rails of the FTB-1 and MAX-710B?

The pack supplies the nominal 14.4 V those devices expect, and its Li-ion chemistry follows the standard charge profile built into each unit.

Will the 148.96 × 41.00 × 23.20 mm case fit the battery bay of an EXFO MAX-730 without modification?

Yes, those exact dimensions match the OEM LO4D318A form factor, so the battery slides into the MAX-730 bay and latches securely.
