Aircraft Battery Market Size, Share & Industry Analysis, By Aircraft Type (Fixed-Wing, (Narrow Body, Wide Body, Regional Jets, Business Jets, and Military Aircraft) Rotary-wing, (Military helicopters and Commercial Helicopters) and UAVs (Commercial UAV and Military UAV)), By Battery Type (Solid Battery, Lithium-ion, Nickel-Cadmium, and Lead-acid), By Application (Propulsion, Start & Backup, Avionics and Cabin, and Others), By End-Users (OEM and Aftermarket), and Regional Forecast, 2025-2032

The global aircraft battery market size was valued at USD 1.86 billion in 2024. The market is projected to grow from USD 1.93 billion in 2025 to USD 3.20 billion by 2032, exhibiting a CAGR (compound annual growth rate) of 7.46% during the forecast period.

Aircraft batteries are onboard power sources that help start engines and APUs, keep avionics and lights running, and provide emergency power if generators fail. They come in four main types: solid-state (emerging), lithium-ion, nickel-cadmium, and lead-acid. New electric aircraft also use large battery cell packs for propulsion as they meet strict safety standards.

More-electric aircraft (MEA) architectures increase battery counts and capacity per tail (including electro-hydraulic brakes, distributed actuators, and power electronics). AAM/eVTOL and defense–commercial UAV fleets shift batteries from auxiliary to mission-critical, driving higher energy and power requirements. Li-ion retrofits improve weight, maintenance, and dispatch reliability while enabling health-monitoring and eTechLog integration. Clearer certification (e.g., DO-311A thermal-runaway containment and DO-160 environmental testing) plus better BMS and thermal design have de-risked adoption after early incidents. Replacement cycles create recurring spend, while growth of the Asia Pacific fleet and missionization in the defense sector contribute to increased volume. Sustainability targets, recycling mandates, and airport electrification further reinforce investment in advanced chemistries and safer pack architectures.

Leaders include Saft, GS Yuasa, Concorde, Teledyne Gill, MarathonNorco, EnerSys/Hawker, True Blue Power, Safran Electrical & Power, Parker Meggitt/Securaplane, Collins, EaglePicher, and electrification specialists EPS, H55, Amprius, Molicel, CUSTOMCELLS, Denchi. They pair certification with BMS/thermal safety, cycle life, field support and tight alignment to eVTOL/Unmanned Aerial Vehicles (UAV) and retrofit roadmaps.

MARKET DYNAMICS

MARKET DRIVERS

More-Electric Aircraft, AAM Ramp, and Higher Battery Content per Tail to Drive Market Growth

Airframers are switching from hydraulics power to electric power (for brakes, actuators, and power electronics), and this shift increases both the number and capacity of batteries per aircraft. At the same time, advanced air mobility (eVTOL/eCTOL) moves batteries from “auxiliary” to “propulsion-critical,” multiplying value per tail and accelerating investment in high-voltage packs, robust BMS, and thermal containment. As regulatory paths clarify, airline and airport pilots integrate certified solutions into the mainstream, while OEM roadmaps standardize interfaces and health-monitoring hooks. The feedback loop for airframes is powerful due to more electric loads, which leads to larger and more complex batteries and propulsion systems, ultimately resulting in stricter safety specifications that cater to business aviation, regional, and rotorcraft operations, thereby driving overall market development.

• January 2025: The FAA finalized rules to integrate powered-lift into operations and pilot certification—an enabling step for eVTOL entry-into-service.

MARKET RESTRAINTS

Tighter Thermal Safety, Handling, and Ops Burden to Constrain the Market for Aircraft Batteries

Lithium-ion’s energy density is compelling but aviation demands impeccable design: cell selection, propagation-resistant structures, controlled vent paths, heaters, and fault-tolerant BMS logic. Operators also carry procedural loads, including carriage limits for spares, cabin crew training, and standardized fire-containment gear, as well as the documentation to display compliance with abuse tests. Mixed fleets and extreme-temperature ops magnify the burden, stretching qualification timelines and adding cost. Even with safer chemistries, airlines still factor in containment hardware and ground-handling controls, slowing adoption in segments where weight savings are marginal. Real-world events keep risk in focus and drive conservative engineering margins.

• October 2025: An Air China A321 diverted after a carry-on lithium battery ignited mid-flight, underscoring persistent thermal-runaway risks and the need for containment and procedures.

MARKET OPPORTUNITIES

Growth Opportunities through UAV Proliferation and Defense Missionization

Unscrewed systems are scaling in number, mission diversity, and sortie rates. This creates the demand for hot-swappable, rapid-charge packs that handle high C-rates, wide temperatures, and repeated abuse while remaining signature-quiet. Defense programs, in particular, are funding the development of ruggedized enclosures, advanced state-of-health analytics, and standardized interfaces across various families. These are the features that lift battery ASPs. Commercial inspection, logistics, and mapping fleets pull similar capabilities but with tighter cost-per-flight-hour targets, creating volume for cell makers and integrators. Furthermore, UAV learning curves in thermal management and BMS propagate quickly into manned retrofits, shortening the time-to-certification for next-gen packs.

• October 2025: A Washington Post investigation documented the surging Chinese exports of lithium-ion batteries and other components feeding Russia’s battlefield drones, highlighting how the UAV demand is expanding battery volumes and tech deployment.

AIRCRAFT BATTERY MARKET TRENDS

High-Voltage Modular Packs to Act as a Major Technological Trend

Across manned and unmanned platforms, architectures are marching to higher voltages with tighter thermal envelopes and BMS that fuse cell diagnostics with flight data to predict remaining useful life. Suppliers are hardening packs against propagation using mechanical isolation, gas management, and materials that tolerate abuse without catastrophic failure. In parallel, IP is consolidating around HV systems, BMS, and electric-propulsion system integration, speeding certification by reusing proven design blocks.

• October 2025: Archer acquired ~300 patents from Lilium covering high-voltage systems, BMS, and ducted-fan e-propulsion, signaling continued consolidation of battery-adjacent IP in aviation.

MARKET CHALLENGES

Fragmented Certification Present Threats to the Market Growth

Only a subset of chemistries, formats, and vendors meet flight-critical reliability along with temperature/abuse requirements. Qualifying alternates is a slow process. Pack integrators must reconcile evolving FAA/EASA expectations, aircraft-specific installation nuances, and evidence for containment and fault tolerance, each of which adds test cycles, documentation, and cost. Downstream operators seek closed-loop recycling and traceability, which complicates procurement but improves lifecycle outcomes. Geopolitics and export controls can pinch separators, electrolytes, heaters, and sensors, stretching lead times. Winners pre-qualify multiple cell sources, design for manufacturability, and standardize interfaces to de-risk change.

July 2025: EASA issued new Acceptable Means of Compliance/Guidance Material for Innovative Air Mobility (Part-IAM), raising clarity but also increasing the evidentiary bar for operations with VTOL-capable aircraft.

The others segment is expected to grow at the highest CAGR of 8.97% from 2025-2032.

By Aircraft Type

Increasing Air Travel Demand Fuels Growth in the Fixed-Wing Segment

Based on aircraft type, the market is segmented into fixed-wing, rotary wing, and UAVs.

The fixed-wing segment held the dominating position in 2024 with more than 60% share. Narrow-bodies (A320/737 families) dominate fixed-wing battery demand due to their large in-service fleets and high utilization, which accelerates the replacement cadence. Weight-saving Li-ion retrofits appeal to carriers on short-haul cycles, while newer airframes expand electric loads (including brakes and actuators), nudging them toward higher capacity. Wide-body aircraft are fewer in number and require slower replacement cycles compared to other fixed-wing aircraft types, such as regional and business jets. These other types of aircraft require faster replacement, thereby fueling demand due to their higher capacity.

• October 2025: Airbus opened a second A320neo line in Tianjin, targeting 75 aircraft per month by 2027, an evidence of sustained narrow-body growth.

The UAVs segment is expected to grow with the highest CAGR of 9.96% from 2025-2032.
