Ugreen FineTrack Two: Ball-Shaped Tracker with Eternal Battery or Junk

Published on May 24, 2026 | Translated from Spanish

Ugreen has introduced the FineTrack 2, a tracker with a soccer ball design intended for keys or bags. Compatible with Apple's Find My network, it features a CR2450 600mAh battery with a lifespan of five to seven years, far surpassing an AirTag. The problem is that this battery cannot be replaced or recharged.

Ugreen FineTrack 2 tracker shaped like a soccer ball being sliced open by a precision rotary cutting tool, revealing an embedded non-replaceable CR2450 battery inside a sealed plastic casing, battery terminal contacts visibly fused to the circuit board, a pair of electronic tweezers attempting to pry the battery free but failing against the molded enclosure, sparks or micro-cracks appearing at the seam during the destructive opening process, technical engineering visualization style, photorealistic macro detail on battery markings and PCB traces, cold industrial lighting with blue and grey tones, metallic tool reflections on the glossy black ball surface, ultra-sharp focus on the battery compartment and tool tip interaction, demonstrating the permanent non-serviceable design

Extended battery life at the cost of sustainability 🔋

The FineTrack 2 uses a non-replaceable CR2450 battery, soldered to the internal circuit to maximize space and duration. This allows the device to function for up to seven years without maintenance, but once the charge is depleted, the tracker becomes unusable. Ugreen prioritizes longevity over repairability, turning a useful gadget into electronic waste programmed to disappear after its life cycle.

The tracker that loses you when it dies ⚽

So, you buy a ball so you don't lose your keys, but when the battery says enough, the ball becomes a digital stone that only serves to take up space in a drawer. And no, you can't change the battery like you would on a wristwatch. It's like having a guard dog that, upon turning seven, becomes a paperweight. Sure, while it lasts, it locates your things with pinpoint accuracy. Then, into the trash.
