Modern miniature electronic products are becoming smaller while requiring longer operating time and more efficient power utilization. The 1254 3.85V 70mAh High Voltage Pouch Coin Lithium Battery is developed for smart devices that need higher voltage output without increasing battery size.
Compared with standard 3.7V lithium polymer cells, this high voltage pouch battery provides a higher nominal voltage platform, helping reduce additional voltage conversion requirements in some applications. Its compact soft-pack structure offers greater design flexibility, making it suitable for narrow internal spaces where traditional rigid batteries are difficult to integrate.
Manufactured by Yideng, this miniature lithium battery combines high voltage performance, stable quality control and customization capability for global electronics manufacturers.
The 1254 pouch coin battery adopts a high-voltage lithium chemistry system to improve energy utilization within a compact form factor.
The 3.85V platform provides advantages including:
- Higher operating voltage compared with standard 3.7V cells
- Improved energy density for miniature devices
- Reduced dependency on additional boost circuits
- More efficient use of limited product space
For smart hardware developers, this allows more flexibility in balancing battery size, runtime and product design.
Unlike conventional metal-shell coin batteries, the 1254 3.85V 70mAh High Voltage Pouch Coin Lithium Battery uses an aluminum laminate pouch structure.
This design provides:
- Slim and lightweight construction
- Better space utilization
- Flexible installation possibilities
- Reduced limitations from rigid battery shapes
The soft-pack structure is especially suitable for compact products with irregular battery compartments, helping engineers optimize internal layouts during product development.
Many miniature devices spend most of their time in standby mode and require reliable energy storage with low power consumption.
The 1254 70mAh LiPo cell features low self-discharge characteristics and stable discharge performance, helping maintain reliable operation for devices such as sensors, smart tags and portable electronic products.
Its consistent internal resistance and controlled manufacturing process also support stable pulse discharge performance for devices with intermittent power demands.
