The PL502121 is a compact lithium‑polymer cell offering a rated capacity of 165 mAh and a nominal voltage of 3.7 V. Its charge‑limit voltage is set at 4.20 V (±0.03 V) and the discharge cut‑off voltage is specified at 3.0 V. The cell measures 21.0 mm × 21.0 mm × 5.0 mm and weighs about 5 g, fitting tightly into space‑constrained designs.
The battery chemistry is lithium‑polymer with a polymer electrolyte, delivering up to 500 charge cycles and featuring dual IC protection chips that guard against short‑circuit, over‑charge, over‑current and overload conditions. Typical self‑discharge for this chemistry is ≤5 % per month and the material tolerates storage temperatures from - 20 °C to 60 °C while operating temperatures for charging are 0 °C to 45 °C. These characteristics make the cell a common choice for wearables, IoT modules and medical monitoring devices.
OEMs source the PL502121 for high‑volume consumer‑electronics production. The supplier lists a minimum order of 2 000 pieces, accepts smaller trial orders, and ships within three to five days after payment. Payment terms include T/T, Western Union or PayPal, and the cells are packed in standard industrial cartons (41 cm × 20 cm × 25 cm). Buyers should confirm current pricing, lead‑time and certification copies before placing an order.

Before placing an order, ask the supplier for the latest datasheet, a full certificate package and a sample test report confirming the 165 mAh capacity, voltage tolerances and safety‑chip functionality. Verifying these documents helps ensure the cells meet your project's specifications and regulatory requirements.
Typical logistics involve shipment from Shenzhen ports within three to five days after payment. Confirm the Incoterm (commonly FOB Shenzhen) and arrange payment via T/T or another mutually accepted method. Discuss any required custom documentation, such as MSDS or UN 38.3 test reports, early in the negotiation.
Implement a quality control plan that includes visual inspection of dimensions and weight, a capacity test at the 1 C discharge rate, and a functional check of the protection ICs. Third‑party inspection agencies can provide an independent report, and the supplier should supply a batch test certificate for each shipment.
