Physical Specifications & Form Factor
Dimensions: Precise dimensions of 7mm (thickness) × 30mm (width) × 48mm (length) (703048 code, where numbers represent thickness × width × length in mm). This slim, rectangular shape is ideal for space - constrained applications like wearable devices, portable electronics, or compact IoT gadgets.
Weight: Lightweight design, typically weighing ~30g (varies slightly by manufacturer), enabling portable devices to remain ergonomic and easy to handle.
Flexible Structure: Unlike rigid lithium - ion batteries, the polymer electrolyte allows minor flexibility in shape (within safe limits), accommodating curved or non - uniform device interiors without damage.
Electrical Performance Parameters
Charge Voltage: Maximum charging voltage of 4.2V (constant - current/constant - voltage charging profile). Charging beyond this voltage risks overheating or capacity degradation.
Discharge Cutoff Voltage: Minimum safe discharge voltage of 2.75V (to prevent deep discharge, which irreversibly damages the cell).
Continuous Discharge Current: Rated for 1C (1000mA) continuous discharge (varies by manufacturer; some versions may support up to 2C (2000mA) for short durations, ideal for devices with occasional high - power bursts, e.g., wireless earbuds during audio playback).
