CR2477W 3V 1000mAh Primary Button Cell characteristics: Lightweight, high voltage and high energy density. (The battery voltage is 3V, which is almost twice that of a normal alkaline or manganese battery. This means that the number of batteries required for the device can be halved to maximize space savings and weight.) Excellent discharge characteristics (Even if it is discharged for a long time, the voltage characteristics are kept stable, which greatly improves the reliability of the device using the battery. This equipment is also maintenance-free (very few batteries need to be replaced).) Excellent temperature characteristics (Murata's original organic electrolytes provide excellent properties in a wide range of temperatures from low to high.) -40 to +125 degrees Celsius (heat resistant), Excellent resistance (Leakage The newly developed battery structure and electrolyte ensure long-term maximum leakage resistance.) Excellent long-term reliability (Carefully selected active materials are used for the active materials and electrolytes. These materials are sealed using Murata's innovative technology to minimize battery self-discharge. The annual self-discharge rate at room temperature and normal humidity is less than 1% of the rated capacity.)
