Features:

High Energy Density

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.

Lightweight and Compact Design

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.

Flexible Installation

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).

Low Self-Discharge Rate

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.

No Memory Effect

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.

Stable Voltage Output

Maintains a consistent 3.7V nominal voltage throughout most of its discharge cycle, providing reliable power to sensitive electronics and preventing performance fluctuations.

Safety Features (with Protective Circuit)

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.
