US Developing Two Military Battery Prototypes

The US Defense Logistics Agency’s Research and Development Office has launched two projects to enhance military batteries.

The efforts support the agency’s Battery Network Program (BATTNET), which aims to improve the safety, quality, shelf life, and operability of batteries powering US armaments.

New Tactical Batteries

One BATTNET project will develop a 6T battery prototype with 35 percent less weight than existing batteries and a bipolar design for greater efficiency.

The battery is expected to lower distribution costs while sustaining power, energy, and longevity.

The other project will focus on a lead-acid battery prototype that uses absorbent glass for enhanced capacity, vibration resistance, and consistency.

The resulting system will replace obsolete technologies supporting 4HN-type batteries in armored fighting vehicle-mounted gun turrets.

The Michigan-based US Army Ground Vehicle System Center will facilitate the trial, qualification, and approval of both prototypes in late 2023.

BATTNET Progress

Established in 2010, BATTNET has supported US warfighters by producing and leveraging manufacturing technologies that bolster tactical battery capabilities and reduce premature disposals.

Last year, the US Department of Defense formed the Federal Consortium on Advanced Batteries and Defense Advanced Batteries Working Group to explore advanced science and new approaches that support combat-related batteries.

“The Defense Logistics Agency procures $200 million of batteries annually. Critical weapons systems, aircraft, ground vehicles and communications systems all rely on long-lasting, durable batteries to maintain America’s global strategic advantage,” a US Defense Logistics Agency’s Research and Development Office statement said.
