Main Selling Points:
Compact & Space-Saving Design: With dimensions of 5mm (thickness) × 20mm (width) × 25mm (length), the 502025 battery features an ultra-slim and miniaturized form factor, ideal for devices with limited internal space.
Stable Voltage Output: Delivers a consistent 3.7V nominal voltage, matching the power requirements of most small electronic devices, ensuring stable performance during operation.
Optimal Capacity for Mini Devices: 200mAh capacity provides sufficient runtime for low-power gadgets (e.g., wearable trackers, small sensors) without adding excessive weight.
High Safety Performance: Adopts lithium-polymer chemistry with built-in protection against overcharge, over-discharge, short circuits, and thermal runaway, reducing safety risks.
Long Cycle Life: Supports 300–500 charge-discharge cycles (under standard usage conditions), offering durable power supply for long-term device use.
Low Self-Discharge Rate: Maintains over 90% of its capacity after 1 month of storage (at room temperature), suitable for devices that require occasional or standby power.
Lightweight Advantage: Weighs only 3–5 grams (typical), minimizing the overall weight of portable devices—critical for wearables and miniaturized electronics.
Key Applications
Mini Wearable Devices: Children’s smartwatches, ultra-small fitness trackers, mini health monitors (e.g., heart rate sensors for sports gear).
Portable Medical Gadgets: Fingertip pulse oximeters, mini blood glucose testers, small handheld thermometers (low power consumption, compact size demand).
IoT & Smart Sensors: Wireless mini sensors (e.g., temperature/humidity sensors for smart homes, asset tracking tags), Bluetooth low-energy (BLE) beacons.
Small Consumer Electronics: Wireless earbud charging cases (auxiliary power), mini Bluetooth speakers, portable USB fans, small remote controls (e.g., for toys or mini drones).
Toys & Mini Models: Micro remote-controlled (RC) cars/planes, mini robotic kits, electronic educational toys (requires lightweight, small-sized batteries).
Backup Power for Micro Devices: Emergency backup power for mini GPS trackers, small USB-powered LED lights, or portable Wi-Fi hotspots (short-term backup needs).
