3.7V 2000mAh 883759 Lithium batteries used for tracker Battery
In IoT and asset tracking, the conflict between device thinness and battery life is the primary design bottleneck. Engineers need a battery that fits ultra-slim enclosures but provides enough energy for frequent GPS pings. The 883759 Li-Polymer battery, with a thickness of only 8.8mm, delivers a robust 2000mAh capacity. This high energy-to-volume ratio allows for sleek tracker designs that can operate for months on a single charge, solving the pain point of frequent maintenance in fleet management and logistics tracking.
• Ultra-Thin Profile: 8.8mm(T) x 37mm(W) x 59mm(L) dimensions, using flexible pouch packaging for slim integration.
• High Energy Density: 3.7V/2000mAh capacity provides headroom for high-current GPRS/LTE data bursts.
• Wide Operating Temp: Formulated electrolyte supports stable discharge in environments from -20°C to 60°C.
• Integrated Protection: Built-in PCM for overcharge, over-discharge, and short-circuit protection.
• OEM Customization: Tailored leads and connectors ensure a “plug-and-play” fit for specific PCB layouts.
