The BAKTH-753450P-1S-3J is a premium lithium polymer battery, featuring a nominal 3.7V voltage (4.2V full charge), 1350mAh high capacity, and 5.09Wh energy output. Engineered with advanced lithium polymer chemistry, a slim prismatic 753450P form factor (75mm × 34mm × 5.0mm), and a stable 1S-3J single-cell configuration, it merges large capacity, ultra-thin flexibility, and reliable performance—making it the ideal power source for wireless earbud charging cases, mid-sized smartwatches, portable Bluetooth speakers, IoT sensors, and other compact-to-midsize consumer electronics that demand extended runtime without sacrificing sleek design.

Engineered for consistent, stable performance in daily use scenarios:

• Stable 3.7V Voltage Output: Maintains a steady 3.7V nominal voltage throughout discharge, avoiding voltage drops that cause device lag, flickering, or sudden shutdowns. This stability is critical for sensitive electronics like smart wearables or IoT sensors, ensuring smooth operation until full depletion.
• Wide Temperature Adaptability: Operates reliably from -20°C to 60°C , performing well in both cold outdoor environments (e.g., winter fitness tracking) and warm indoor settings (e.g., home IoT devices) without compromising performance.
• No Memory Effect: Supports partial charging without capacity degradation. Users can top up the battery anytime (e.g., during work breaks or commutes) without affecting its long-term performance, adapting to busy lifestyles.

• Wearable Devices: Mid-sized smartwatches, fitness trackers, and wireless earbud charging cases.
• Portable Audio & Video: Mini Bluetooth speakers, portable media players, and small digital cameras.
• IoT & Smart Home Devices: Bluetooth beacons, environmental sensors (temperature/humidity), and smart doorbell backup power.
• Handheld Gadgets: Mini handheld game consoles, portable scanners, and keychain power banks (mini models).
• DIY & Custom Projects: Arduino-based gadgets, small drone prototypes, and custom wearable electronics.
