100-0201-01 – Securaplane XL246-A Emergency Backup Battery System

Available now on the Airparts.aero Marketplace.

The Securaplane 100-0201-01 (Model XL246-A) is a high-performance, flight-critical emergency backup battery system designed specifically for the Gulfstream GIV/GIV-SP/GV series aircraft. As a central component of the aircraft's emergency power infrastructure, this unit provides a reliable, independent power source for essential avionics, emergency lighting, and flight control systems in the event of a primary power generation failure. Engineered using advanced Valve Regulated Lead Acid (VRLA) technology, the XL246-A is designed to deliver high discharge rates with superior voltage retention, ensuring that critical systems remain operational during the most demanding phases of emergency flight operations.

This Securaplane system is more than a simple battery; it is a sophisticated power management solution. It incorporates internal charging circuitry and monitoring logic that ensures the battery remains at peak state-of-charge (SoC) during normal operation while providing instantaneous transition to discharge mode when the bus voltage drops below a specified threshold. Its ruggedized construction is optimized for the harsh environmental conditions of the avionics bay, including high-frequency vibration and extreme thermal gradients. For procurement specialists and maintenance directors, the 100-0201-01 represents the gold standard in emergency power, offering a proven MTBF (Mean Time Between Failure) that minimizes unscheduled maintenance and maximizes fleet readiness.

Key Features

• Advanced VRLA Technology: Utilizes absorbed glass mat (AGM) separators to immobilize electrolyte, allowing for an aerobic recombination cycle that eliminates the need for water replenishment and prevents leakage in any orientation.

• Integral Charging & Control Logic: Features built-in circuitry that manages the charging profile to prevent thermal runaway and optimize battery longevity.

• High Power-to-Weight Ratio: Engineered with thin-plate pure lead technology to provide maximum cranking and standby power without the weight penalty of traditional flooded-cell batteries.

• Low Self-Discharge Rate: Designed for extended shelf life and operational readiness, even after periods of aircraft inactivity.

• Vibration and Shock Resistance: The internal plate groups are highly compressed and secured to withstand the rigorous G-loads and airframe resonances characteristic of high-performance turbine aircraft.

Why Choose 100-0201-01?

Choosing the OEM Securaplane XL246-A ensures total system integration with the Gulfstream power distribution architecture. Unlike generic lead-acid alternatives, the 100-0201-01 is tuned to the specific impedance and charging characteristics of the aircraft’s DC generators. Utilizing non-certified or "look-alike" batteries risks premature failure, internal plate sulfation, or inadequate duration during a genuine emergency. By adhering to the Securaplane standard, operators ensure maximum safety margins and compliance with stringent Part 91/135/121 regulatory requirements.

The 100-0201-01 utilizes a sophisticated Valve Regulated Lead Acid (VRLA) design that relies on the principle of oxygen recombination. During the charging phase, oxygen gas is evolved at the positive plate. In a traditional flooded battery, this gas would escape, leading to electrolyte depletion. However, in the XL246-A, the oxygen diffuses through the highly porous Absorbed Glass Mat (AGM) separator to the negative plate, where it reacts to form lead sulfate and eventually water. This closed-loop chemical process makes the unit virtually maintenance-free and eliminates the risk of acid spills. The battery's grid is typically constructed from a high-purity lead-tin alloy, which provides superior corrosion resistance and minimizes the "gas-off" effect. Furthermore, the internal architecture is designed to minimize Equivalent Series Resistance (ESR), allowing the battery to deliver high current pulses without a significant voltage drop, a critical requirement for maintaining avionics stability during transient loads in an emergency power-down sequence.

Note: The 100-0201-01 is a flight-critical emergency component. Maintenance personnel must strictly adhere to the capacity check intervals specified in the Gulfstream Chapter 5 Time Limits/Maintenance Checks. This unit contains hazardous materials (Lead/Acid) and must be disposed of according to environmental regulations. Installation must be performed by a certified A&P mechanic or authorized repair station in accordance with the Securaplane Component Maintenance Manual (CMM) and the Aircraft Maintenance Manual (AMM).
