MIL-STD-810G is a rigorous U.S. military standard that subjects equipment to a range of environmental stress tests. Method 512.6 – Immersion Testing focuses on evaluating the waterproof performance of a device, typically requiring it to withstand immersion in 1 meter of water for 30 minutes without performance degradation.
Shenzhen Power-Time Technology Co., Ltd., a trusted name in military power solutions, put its BB-2590/U batteries to the ultimate waterproof test during the China International Exhibition on Police Equipment (CIEPE) in Beijing, May 2025.
At their booth, Power-Time fully submerged their BB-2590/U batteries in water for four consecutive days—far exceeding the MIL-STD-810G standard. Remarkably, the batteries remained fully functional throughout the entire exhibition.
This live demonstration proved more than just compliance with laboratory standards—it showed real-world durability. Key benefits include:
Superior Sealing: Power-Time's engineering ensures zero water ingress, protecting internal circuits even during prolonged immersion.
Operational Integrity: Even after four days underwater, the batteries were able to power devices flawlessly—no malfunctions, no degradation.
Field-Proven Resilience: Ideal for missions involving maritime operations, amphibious landings, and extreme weather conditions.
Waterproof reliability is not optional—it's mission-critical. Shenzhen Power-Time's BB-2590/U batteries have not only passed MIL-STD-810G immersion testing but have also proven themselves in a live demonstration. For defense professionals seeking power solutions that won’t fail in the field, Power-Time’s BB-2590/U delivers confidence, capability, and compliance.
