11500 3.7V 500mAh Cylindrical Lithium Polymer Battery Cell for Portable Devices
The 11500 is a cylindrical lithium polymer cell with a nominal capacity of 500mAh and nominal voltage of 3.7V, built in a round format of approximately 11.0 mm diameter × 50.0 mm length. Its larger 500mAh capacity provides longer runtime than compact 08400 or 09500 cells, while the slim round body still fits neatly into small products.
The soft-pack cylindrical design keeps the cell lightweight and easy to integrate, making it a dependable rechargeable power source for portable electronic devices. Capacity and connections can be customized to suit your specific product requirements.

If your product requires a specific round cell size or capacity, our engineering team can confirm the design before mass production.
Each cell undergoes thorough inspection for appearance, voltage, and capacity before shipment. All products are packed in industrial cartons that comply with international air and shipping standards for lithium batteries.
In-stock items are dispatched quickly, while custom and bulk orders are produced within 2 to 3 weeks after confirmation. Sample testing is available so buyers can verify dimensions and electrical performance before committing to volume orders.
