Storage and handling: Store separately in a cool (less than or equal to 25 degrees Celsius) dry area for long-term storage, away from direct sunlight, heated environments, and high static environments. Keep away from children or pets. During transport, check positive and negative directions before packaging and verify insulation to prevent short circuits. When monomers are used for module or component assembly, adopt the first-in, first-out principle. Do not soak or wet the cell with water or seawater, and do not place it in microwave ovens or high-voltage containers.
Warnings: Incorrect use may lead to heating, fire, and performance degradation. Do not use different chargers; do not charge beyond the maximum charging current; do not disassemble or reinstall the battery; do not throw or cause impact; do not pierce the battery with sharp objects; do not use the cell together with other battery systems; do not package old and new batteries together; do not expose the battery to high temperatures such as fire; do not put the battery in a microwave oven or high-voltage container; do not connect the positive and negative terminals with conductive materials; do not allow the battery to be soaked or wet by water or seawater. Do not place the battery in direct sunlight or heated environments; do not use batteries in high static environments. Batteries must be kept away from children or pets. When rust or odor is detected during first use, return the product to the seller immediately. When battery life shortens after prolonged use, replace it with a new battery. Do not wear metal objects such as wristbands or watches when handling batteries. The charging time shall not exceed the time specified in the manual. Do not expose the battery outside the operating temperature range specified in this document. For any matters not covered in this specification, please consult with Jianheng.
Jianheng warrants that the SIB50160118-50H-2.85V-6C-1602 sodium-ion cell is free from defects in materials and workmanship under normal use and service for a period of 12 months from the date of shipment or 24 months from the date of manufacture, whichever occurs first, unless otherwise agreed in writing. The warranty is subject to the cell being stored, charged, discharged and operated strictly in accordance with this specification. The warranty does not cover damage resulting from overcharge, over-discharge, external short circuit, mechanical abuse, immersion in water or seawater, use with incompatible chargers or battery systems, mixing old and new cells, disassembly, or any use outside the specified operating conditions. The warranty is limited to replacement or repair of defective cells at Jianheng's discretion and does not cover consequential or incidental damages.
