The Sum Electronics Technology Co., Ltd. offers a 3.7 V lithium‑polymer pouch cell designed for compact power applications. The cell measures 4.9 mm × 20 mm × 98 mm and delivers a nominal capacity of 1000 mAh with a charge voltage of 4.2 V and a charge current of 1.4 A. It is classified as a lithium polymer battery and complies with CE, RoHS and IEC 62133 standards. The product is shipped from the Dongguan facility in Guangdong, China.
The battery uses a lithium‑polymer electrolyte that provides higher energy density and lower weight than conventional cylindrical cells. Its aluminium‑foil jacket gives a leak‑proof seal and the cell is rated for operation between - 40 °C and 80 °C, a range typical for portable electronics. The technical standard GB/T8897.2‑2013 governs its safety performance, and the manufacturer reports no leakage, deformation or rust during the five‑year shelf‑life warranty. Such characteristics match industry expectations for wearable devices and IoT modules.
Typical buyers include manufacturers of power banks, smart wearables and other compact consumer electronics that require ultra‑long standby capability. The battery is supplied in blister cards, shrink packs or cartons with 2 or 4 pieces per pack, and the supplier states a daily capacity of 100 million pieces. Lead time is listed as delivery within two days from the Shenzhen port, and the seller welcomes OEM customisation. Importers should confirm the minimum order quantity and payment terms directly with the supplier.
