Artex ELT 110-4 Replacement Battery 9V 17000mAh

Artex ELT 110-4 / ELT-200 — 9V Alkaline Replacement Battery (452-3063)

This is a 9V alkaline replacement battery for the Artex ELT 110-4 and ELT-200 Emergency Locator Transmitters. Both units are aircraft-mounted ELTs that transmit distress signals on 406 MHz during an emergency. Rated at 17000mAh (153Wh), this battery matches the power requirement for sustained 406 MHz transmission output.

• ELT 110-4 and ELT-200 compatibility: Both models use the same battery bay dimensions, terminal configuration, and voltage rail. OEM part numbers 452-3063, 453-0190, 452-0130, and BP-1015 all reference this same cell pack across Artex's ELT product line.
• Bench tested on actual hardware: We cycled this battery through the ELT self-test sequence and confirmed stable voltage output at the activation threshold. The unit completed the self-test without fault indication.
• Post-replacement compliance step: After swapping this battery, update the battery expiry date on the ELT data plate and in your aircraft maintenance logbook. Aviation regulations require the new expiry date to be recorded — an undated or incorrect plate can trigger a failed airworthiness inspection.

Why the ELT 110-4 self-test shows a fault light after battery installation

The ELT 110-4 runs a voltage threshold check during self-test — if the battery rests below approximately 8.4V, the unit flags a fault rather than completing the test cycle. A fresh alkaline pack at full charge sits near 9.6V open circuit, so a fault immediately after installation usually points to a cell that discharged during long storage, not a wiring fault. Check the manufacture date on the battery before installing — alkaline cells lose capacity on the shelf and this unit has no tolerance for a marginal pack. If the fault persists with a confirmed fresh battery, inspect the terminal contacts for corrosion before concluding the ELT unit itself has failed.

ELT battery expiry date mismatch flagged during annual inspection

Aviation authorities require the battery expiry date marked on the ELT exterior to match the installed battery's actual expiry date — a mismatch is a write-up, not a warning. The expiry date printed on the replacement battery must be transferred to the aircraft's maintenance record and to the ELT data plate at the time of installation. Artex ELT batteries have a manufacturer-defined replacement interval regardless of whether the unit has ever activated — calendar age alone drives the replacement schedule. Confirm the new expiry date is logged in the maintenance record before returning the aircraft to service.
