Compatible EXFO XW-EX003 Replacement

This two-pack replaces the EXFO XW-EX003 battery in AXS-100, AXS-110 and AXS-110 OTDR units. Each cell delivers 3.7V and 2300mAh for extended field sessions. Built-in protection circuits guard against over-charge, over-discharge and over-heating.

Verify Device Model Before Ordering

Confirm your instrument appears in the supported list: AXS-100, AXS-110, AXS-110 OTDR, FIP-400-D, FLS-600, FPM-600 or FVA-600. The pack contains two identical 3.7V lithium-ion cells rated at 8.51 Wh each. No charger is included so use your existing charging equipment.

Steady Output During Long Tests

Protection circuitry maintains stable voltage across continuous OTDR or fibre-inspection runs. Over-current and over-voltage safeguards prevent shutdown when the load persists for hours. The 2300mAh capacity supports repeated measurements without frequent swaps.

Questions about this item

Does the 2-pack include everything needed to charge the batteries or must a charger be bought separately?

The pack contains two 3.7V 2300mAh lithium-ion batteries only; a compatible charger is not included and must be purchased separately.

Both batteries are the same NP-120 2300mAh version, so there is no capacity choice to make?

Correct, the 2-pack supplies two identical NP-120 cells rated at 3.7V and 2300mAh each, giving 8.51Wh per battery.

Will a single 2300mAh NP-120 battery run an AXS-110 OTDR for a full field day?

Run-time depends on the instrument's power draw; the cell stores 8.51Wh at 3.7V, so divide that by the device's wattage to estimate hours.
