18650 3.7V 2500mAh 10mR (سعة حقيقية) Lithium Battery بطارية ليثيوم

Model: 18650 3.7V 2500mAh 10mR (سعة حقيقية). This battery is an 18650-size rechargeable lithium-ion cell specified at a nominal voltage of 3.7V and a rated capacity of 2500mAh. The listed internal resistance is 10 milliohms (10mR), and the Arabic phrase "سعة حقيقية" indicates that the capacity is presented as the true usable capacity. Form factor and compatibility: The 18650 format is a widely used cylindrical cell dimension, suitable for devices and battery packs designed to accept 18650 cells. This product is intended for applications that require a single 18650 cell or assemblies built from one or more 18650 cells. Confirm device compatibility and polarity before installation. Charging and handling: Use an appropriate charger designed for 18650 lithium-ion cells and for a 3.7V nominal chemistry. Charge only with chargers that monitor cell voltage and terminate charging at the correct voltage. Do not attempt to charge with an incompatible charger or apply voltages beyond recommended limits. Avoid short circuits, mechanical damage, and exposure to high temperatures or open flame. Storage and transportation: Store in a cool, dry place away from direct sunlight and heat sources. Keep cells separated or insulated to prevent accidental contact between terminals. Follow local regulations for transportation and disposal of lithium-ion batteries. Safety and precautions: Lithium-ion cells can pose hazards if misused. Do not disassemble, crush, puncture, or immerse the cell in liquid. If the battery becomes hot, emits an odor, changes color, leaks, or shows any abnormal behavior, stop use immediately and handle according to battery safety guidelines. Keep out of reach of children. For professional or high-risk applications, consult qualified personnel for safe integration and protection circuitry requirements.
