4000mAh 3.7V Lithium Ion Battery – 9.5 × 54 × 65mm

4000mAh 3.7V Lithium Ion Battery for Portable Projects

The 4000mAh 3.7V Lithium Ion Battery provides rechargeable energy storage for compatible electronic devices. With listed dimensions of 9.5 × 54 × 65mm, it can be considered for projects where the battery compartment and electrical requirements match.

For electronics enthusiasts, students, and developers in Pakistan, this battery offers an option for portable prototypes. Check your complete power system before selecting it, including the charger, protection circuitry, and connected load.

Capacity and Operating Time

The listed capacity is 4000mAh. Actual operating time depends on the device’s current consumption, conversion losses, operating conditions, and the battery’s condition.

Capacity alone does not establish how much current the battery can safely deliver. Confirm the manufacturer’s continuous and peak discharge ratings before using it with motors, heaters, or other demanding loads.

Check the Physical Fit

Measure the available space in your enclosure before ordering. Allow room for the leads, connector, insulation, and appropriate mounting.

Do not compress, bend, puncture, or force the battery into a tight compartment. Secure it so that sharp edges and moving parts cannot damage its casing or wires.

Compatible Applications

Subject to verified electrical requirements, possible uses include:

• Portable sensor projects.
• Rechargeable electronics prototypes.
• Small monitoring devices.
• Educational battery-powered circuits.
• Replacement applications matching the original battery specifications.

A matching nominal voltage does not guarantee replacement compatibility. Also compare dimensions, connector wiring, protection features, and charging requirements.

Charging and Power Connections

Use a charger specifically matched to the battery’s chemistry and manufacturer-specified charging limits. The stated 3.7V is its nominal voltage, rather than an instruction to charge it from a 3.7V supply.

Confirm whether protection circuitry is included. Check connector polarity before connection, and use suitable voltage regulation when powering devices that require a different supply voltage.
