Product Description
703040 Rechargeable 3.7v 850mah Lithium Polymer Battery for high power discharge rate
Features
- High Energy Density: Li-Po chemistry offers a high capacity-to-size ratio, providing 850mAh in a compact, slim form factor (7.5x30x40mm).
-
Flexible Form Factor: The pouch cell design allows for a thin and relatively flexible profile compared to cylindrical cells.
-
High Discharge Rate: Capable of supporting discharge rates suitable for high-power applications (up to 1C continuous, with protection allowing higher pulses).
-
Long Cycle Life: Can withstand over 500 charge-discharge cycles while maintaining more than 80% of its initial capacity.
-
Integrated Protection Circuit ( typical): Often includes a Protection Circuit Module (PCM) providing:
-
Overcharge Protection: 4.20V ± 0.05V
-
Over-Discharge Protection: 2.7V ± 0.1V or 3.0V ± 0.1V
-
Over-Current Protection: 3.0±1.0A or 2.0±1.0A
-
Short Circuit Protection
-
-
Low Self-Discharge: <3% per month (at room temperature).
-
No Memory Effect: Can be recharged at any state of charge without capacity reduction.

Warnings & Precautions
Charging
- Charge Within Specifications: Do not charge above the maximum voltage of 4.2V or exceed the maximum charge current (typically 1C or 850mA).
- Temperature Monitoring: Charge only within the specified temperature range (0°C to 45°C). Never charge a battery that is below freezing (0°C) or feels hot to the touch.
- Use in Safe Area: Charge on a non-flammable surface and away from flammable materials.
- Avoid Over-Discharge: Stop using the battery before reaching the cut-off voltage (2.5V - 3.0V, refer to PCM specifics).
- Respect Current Limits: Do not exceed the maximum continuous discharge current (Typically 1C/850mA, check specifics for your cell).
- Temperature Management: Avoid discharging outside the recommended temperature range (-20°C to 60°C).
Storage
- Partial Charge Storage: For long-term storage (longer than one month), store the battery at a 30%-50% State of Charge (SOC).
-
Cool and Dry Environment: Store in a cool, dry place away from direct sunlight, moisture, and heat sources. Ideal storage temperature is often between -10°C to 25°C or -20°C to 45°C .
-
Fireproof Container: For extended storage or multiple batteries, consider using a fireproof/li-po safety bag or container.
