Features:
With a nominal voltage of 3.7V and 1200mAh capacity, this battery offers a compact yet efficient energy storage solution, delivering approximately 4.44Wh of energy in a lightweight package (dimensions: ~50x37x59mm). It balances power output and portability, making it ideal for space-constrained devices.
The slim, rectangular form factor (503759) and low weight (typically ~50-60g) reduce the overall payload of devices, enabling sleek, portable designs without compromising on capacity. This is critical for applications where minimizing size and weight is essential.
Its flat, uniform shape allows easy integration into tight spaces or custom enclosures, supporting versatile mounting in devices with non-standard layouts (e.g., curved or slim profiles).
The battery retains charge efficiently, losing only ~5-10% of its capacity per month when stored at room temperature. This ensures consistent performance even after periods of inactivity, reducing the need for frequent recharging.
Users can charge the battery at any state of charge without reducing its lifespan or capacity, offering convenience and flexibility in daily use. Full discharges are unnecessary, simplifying battery management.
Maintains a consistent 3.7V nominal voltage throughout most of its discharge cycle, providing reliable power to sensitive electronics and preventing performance fluctuations.
When paired with a built-in protective circuit module (PCM), it safeguards against overcharging, over-discharging, and short circuits, minimizing risks of thermal runaway or damage.
