A-Grade 3.7V 800mAh 14500 Li-ion Cell BAKTH-14500-1S-3W for Bulk Replacement
The BAKTH-14500-1S-3W is a high-performance cylindrical lithium-ion (Li-ion) battery engineered for portable electronics, featuring a standard 14500 form factor (14mm diameter × 50mm length), nominal 3.7V voltage (4.2V full charge), and 800mAh capacity—delivering 2.96Wh of reliable energy. Designed as a direct replacement for disposable batteries or low-quality rechargeables, this battery merges compact size, stable output, and long-lasting performance, making it the ideal power source for small consumer electronics, IoT devices, and everyday gadgets that demand portability without compromising on runtime.
Core Advantages for Portable Device Needs
Crafted to solve the points of small electronics—short battery life, bulky power sources, and inconsistent performance:
14500 Standard Size Compatibility: Fits seamlessly into devices designed for 14500 batteries (a popular mid-sized cylindrical format), including flashlights, digital cameras, wireless headphones, and portable sensors. Its compact dimensions make it perfect for slim, lightweight gadgets where space is at a premium.
800mAh Balanced Capacity: Delivers just the right amount of power for low-to-medium drain devices: powering a mini flashlight for 8-10 hours, a wireless mouse for 2-3 weeks (daily use), a portable Bluetooth speaker for 3-4 hours, or an IoT temperature sensor for 1-2 months (depending on data transmission frequency).
Stable 3.7V Voltage Output: Maintains consistent 3.7V nominal voltage throughout discharge, avoiding the voltage drops that cause flickering lights, lagging devices, or sudden shutdowns. This stability is critical for sensitive electronics like digital cameras or smart home sensors, ensuring smooth operation until full depletion.
Long Cycle Life: Supports 300+ deep charge-discharge cycles (retaining 80% of original capacity), outperforming disposable batteries and generic rechargeables. This reduces long-term costs and environmental waste, making it a sustainable choice for everyday use.
Ideal For:
Consumer Electronics: Flashlights (mini/portable models), digital cameras, wireless headphones, portable media players, and handheld game consoles.
Smart Home & IoT Devices: Wireless mice/keyboards, Bluetooth beacons, environmental sensors (temperature/humidity), and smart doorbells (backup power).
Everyday Gadgets: Electric toothbrushes, portable shavers, mini fans, and handheld scanners.
Emergency & Backup: Emergency flashlights, portable radios, and small medical devices (e.g., glucose meters).
