Key Advantages
1. Small Smart Wearable Devices: The Core Choice for Fit and Low Power Consumption
These devices are typically tiny, designed to fit snugly on the body (such as the wrist or ear), and feature concentrated functions (primarily sensing and display). They consume very little power, with a 1000mAh battery providing 1-2 weeks of battery life. A 4.0mm thickness allows for seamless integration into the body.
Typical Devices:
Entry-level smart bracelets (without complex functions, simply counting steps, heart rate, and notifications);
Children's smartwatches (with small dials, primarily for location tracking and calls, without the need for long battery life);
Wireless earphones (some single-ear earphones or small charging cases, with a 1000mAh battery providing 3-5 charges).
2. Mini Consumer Electronic Accessories: Small size and basic battery life
These devices are primarily focused on portability and lightweight design. They offer simple functions (such as lighting and playback) and do not require high-capacity batteries. Ultra-thin, elongated batteries maximize internal space savings. Typical devices:
Long Bluetooth speakers (palm-sized, 1000mAh battery provides 4-6 hours of playback, suitable for short trips);
Portable LED flashlights/fill lights (low-power LED lights, 1000mAh battery provides 8-12 hours of continuous use);
Small voice recorders (ultra-thin design, suitable for short recordings only, 1000mAh battery provides 10-15 hours of recording);
E-cigarettes (some ultra-thin e-cigarettes, 1000mAh battery provides 1-2 days of regular use, and safety features reduce risks).
3. Smart Home and Internet of Things (IoT) Sensors: Low Power Consumption + Long Standby
Small sensors in smart homes typically require less frequent charging and are installed in limited space (such as on walls or in furniture crevices). The "small size + low self-discharge" characteristics of these batteries (polymer batteries have a monthly self-discharge rate of less than 5%) enable long-term standby operation.
Typical devices:
Wireless door and window sensors (only detects open and close status, consumes very little power, and a 1000mAh battery provides 1-2 years of battery life);
Mini temperature and humidity sensors (such as desktop sensors and sensors inside refrigerators, with low-frequency data transmission and a battery life of 6-12 months);
Smart doorbells (small wireless doorbell indoor receivers, which do not require high power consumption and a 1000mAh battery provides 6-8 months of battery life).
4. Small medical and healthcare devices: Portability and safety are prioritized
Some small household medical devices require frequent portability and use, placing high demands on size and safety. The ultra-thin design and polymer safety characteristics of this battery are well-suited to these needs.
Typical devices:
Portable blood glucose meter (small body, used only for single blood draw tests, 1000mAh battery supports 50-100 tests);
Small oximeter (finger-clip design, low power consumption, 1000mAh battery provides 4-6 hours of continuous use);
Electronic thermometer (ultra-thin design, 1000mAh battery supports hundreds of measurements, eliminating the need for frequent battery replacement).
5. Other Niche Small Devices: Customized Space Adaptation
Some devices, due to their unique structure, require "non-standard-sized" batteries to fill narrow/ultra-thin spaces. The long strip format of these specifications allows for flexible adaptation.
Typical devices:
Handheld small barcode scanners (mini models, suitable for short-distance scanning in retail and warehousing, with a 1000mAh battery capable of half a day's use);
Children's toys (such as small remote-controlled cars and electronic building blocks, with a small capacity suitable for short playtime and a safety design to prevent children from using them);
Ultra-thin card-type MP3/USB flash drives (card-sized storage and playback devices, with a 1000mAh battery capable of 8-10 hours of music playback).
