Cellulose batteries make the Nimble GPS device exceptionally thin and environmentally friendly.
Nimble has just unveiled four new GPS devices that use cellulose-based batteries instead of traditional coin batteries, support wireless charging, and are biodegradable.
Nimble, a manufacturer of tech accessories, has officially launched four new generation tracking devices featuring a breakthrough in energy storage technology. Completely different from the Apple AirTag, which uses a traditional CR2032 coin battery, Nimble's new products are equipped with a unique cellulose-based battery.
Cellulose battery technology: A breakthrough in ultra-thin design.
The application of cellulose batteries not only helps Nimble's GPS devices achieve impressive thinness but also completely revolutionizes the way energy is charged. Instead of having to replace physical batteries periodically like current solutions, users can wirelessly charge the device, providing maximum convenience during long-term use.

Green solutions for electronic waste.
The most notable feature of this type of battery lies in its sustainability. According to the manufacturer, the cellulose battery is biodegradable after its lifespan. This is seen as a solution to the problem of electronic waste from small devices, which is very difficult to recover and recycle with conventional lithium-ion batteries.
Comparing the specifications between Nimble Tracker and Apple AirTag
Below is a preliminary comparison table based on core technical specifications between Nimble's new solution and its competitor from Apple:
| Characteristic | Nimble Tracker | Apple AirTag |
|---|---|---|
| Battery type | Cellulose batteries (plant-based) | CR2032 coin battery |
| Charging mechanism | Wireless charging | Manual battery replacement |
| Thinness | Superior performance thanks to flexible battery structure. | Limited by the thickness of the coin pin. |
| Environment | Biodegradable | Difficult to recycle |
Impact on the smart accessories market
The introduction of these four tracker lines not only provides an alternative to AirTag but also affirms Nimble's position in developing environmentally friendly products. Furthermore, diversifying the product range with four different versions makes it easier for users to choose a device that suits their needs, from locating wallets and keys to other small personal items.
Overall, by combining advanced battery technology with environmental awareness, Nimble is setting a new standard for the personal GPS device segment in the near future.
