3.7V 500mAh 303450 Lithium Battery

3.7V 500mAh 303450 Lithium Battery is a rechargeable single-cell lithium battery specified by its nominal voltage, rated capacity, and form factor. The designation identifies a compact, cylindrical/prismatic cell designed for applications where a 3.7V nominal voltage and approximately 500mAh capacity are appropriate. This product is intended for integration into small electronic devices, portable modules, backup power circuits, and custom battery packs that require the stated electrical characteristics.Handle and store the battery following standard lithium battery precautions. Avoid short circuits, mechanical damage, excessive heat, deep discharge beyond the cell's recommended limits, and exposure to water or corrosive environments. Charge and discharge with compatible chargers and protection circuitry to maintain safe operation and to extend service life. Use of a battery management system (BMS) or protection circuit is recommended when assembling multiple cells into packs to ensure balanced charging and to prevent overcharge, over-discharge, and unintended current paths.For transportation, storage, and end-of-life disposal, observe applicable local regulations for lithium batteries and follow carrier requirements. Check the cell's markings and accompanying documentation for specific storage temperatures, recommended charge current, and authorized recycling or disposal procedures. When replacing batteries in equipment, confirm the cell's physical dimensions and terminal configuration to ensure proper fit and contact. If you require exact mechanical dimensions, cell chemistry variants, safety certifications, or cycle life data, please consult the manufacturer datasheet or request technical specifications from your supplier.
