The Sum Electronics model 803040 is a lithium‑polymer rechargeable cell measuring 8 × 30 × 40 mm, with a nominal voltage of 3.7 V and a fully charged load voltage of 4.2 V. It delivers a nominal capacity of 1000 mAh and a charge current of 1.4 A, packaged in an aluminium‑foil jacket. The battery type is listed as standby‑power, suitable for devices requiring long‑term low‑drain operation. All units are supplied with CE, RoHS, UL, FCC, IEC 62133 and UN 38.3 certifications as stated by the supplier.
The cell chemistry combines a lithium‑cobalt‑oxide/NCM cathode with a graphite anode and a polymer electrolyte, a composition common to high‑energy thin‑form‑factor batteries. Typical industry specifications for similar Li‑Po cells include an operating temperature range of - 20 °C to 60 °C and a cycle life of 300‑500 full charge‑discharge cycles. The supplier claims a five‑year shelf‑life warranty and a leakage‑free, non‑polluting design. Standard safety tests such as IEC 62133 are applied, providing protection against short circuit and over‑voltage.
These dimensions and energy density make the 803040 suitable for wearables, IoT sensors, medical monitoring equipment and other compact electronics. B2B buyers typically order the cells in bulk, with packaging options of 2‑pcs, 4‑pcs blister packs or shrink‑wrapped cartons. The supplier indicates a daily production capacity of 100 million pieces and a lead time of delivery within two days from the Shenzhen port. Potential purchasers should confirm the minimum order quantity, accepted Incoterms and payment conditions directly with Sum Electronics before finalising the contract.
