Product overview
The Jiangsu Sunpower INR21700-5800 is a portable rechargeable lithium-ion cell for electrical energy storage. Its product configuration is an individual cell with ternary-material chemistry, a nominal capacity of 5800mAh and a nominal voltage of 3.6V. Rated energy is 20.88Wh, while cell weight is 70 ± 2g. Its declared material composition includes aluminium at 4.93%, cobalt at 1.68%, copper at 11.68%, lithium at 2.88% and nickel at 22.61%, each exceeding the stated 0.1% threshold by weight.
Handling restrictions prohibit disassembly, crushing, puncturing and disposal in fire. The cell must not be exposed to a high-temperature environment or used after immersion in water, and serious bulging also rules out use. Users must read the instruction manual to reduce injury risk and recycle or dispose of the battery properly. Suitable extinguishing agents are FK-5-1-12 or a water-based extinguisher. The restricted-substance declaration addresses applicable REACH Annex XVII limits while explicitly excluding mercury, cadmium and lead.
