Major Growth Drivers

·         Military Modernization:

Military modernization programs are a primary force behind market expansion. Armed forces are replacing legacy systems with digital communication equipment, electronic warfare capabilities, precision-guided weapons, advanced vehicles, and network-centric infrastructure. These systems require dependable energy storage, making high-performance military batteries an increasingly important component of defense procurement.

Growing defense investments amid heightened geopolitical tensions are also supporting demand. Governments are focusing on lightweight, high-energy-density, long-lasting batteries that can improve the performance and endurance of next-generation military equipment.

·         Unmanned Systems:

The increasing deployment of unmanned aerial vehicles, unmanned ground vehicles, and unmanned underwater vehicles is creating additional battery requirements. These systems depend on lightweight, high-capacity, and long-endurance power sources for surveillance, reconnaissance, intelligence, and other mission-critical operations.

The airborne battery segment is projected to register the fastest CAGR of 4.5%, supported by growing UAV deployment and rising investment in defense aviation technologies. Rechargeable batteries are also expected to register a faster CAGR of 5.3%, reflecting the growing need for reusable power solutions for UAVs and UGVs.

·         Soldier Systems:

Portable soldier systems are another important source of demand. Communication devices, surveillance equipment, wearable technologies, and other electronic systems require dependable batteries that can function during extended field operations.

Ground batteries held the largest platform share at 47.5% in 2025, supported by extensive deployment across land-based military equipment. Frequent field use and replacement requirements also contribute to aftermarket demand.

Specific Battery Chemistries

Battery composition is a major area of differentiation within the market. Rotary lithium-based batteries accounted for the largest composition share at 49.0% in 2025. Their high energy density, lightweight design, reliability, fast-charging capabilities, and suitability for drones, portable communication equipment, and weapon systems make them valuable for modern defense applications.

The nickel-based segment is projected to achieve the fastest CAGR of 5.1%. Its durability, energy density, consistent power delivery, and temperature resilience make it suitable for radios, night-vision equipment, UAVs, and other high-reliability applications.

Non-rechargeable batteries dominated the type segment with a 30.5% revenue share in 2025. Their long shelf life, energy density, and reliable performance make them suitable for applications where uninterrupted power is essential.

Solid-state batteries represent an important technology opportunity because of their potential for higher energy density, improved safety, and longer operational life. At the same time, lithium-ion systems face safety concerns involving overheating, mechanical damage, internal short circuits, and thermal runaway.
