    Panasonic button batteries can achieve long-term stable power supply and are a reliable guarantee for RTC. Taking Panasonic's CR2032 button battery as an example, in a room temperature environment of 20 ℃, combined with RTC modules, it can achieve continuous power supply for more than 10 years, while Panasonic BR type batteries can even achieve a lifespan of more than 15 years.

The secret to ultra long power supply comes from the long-term stability of the internal resistance of Panasonic batteries, excellent high-temperature storage performance, and special structural design.

    The internal resistance of a battery refers to the resistance experienced by the current passing through the battery, and is an extremely important parameter of a chemical power source. It is related to materials (positive and negative electrode materials, diaphragm electrolytes, etc.), structure, and assembly process. Panasonic's unique manufacturing process ensures that the battery always maintains low internal resistance. When the current passes through the circuit, it encounters less internal resistance and consumes less energy. Compared with ordinary button batteries on the market, Panasonic batteries are resistant to high temperatures and have stable performance. Even in the end of device use, they still maintain a low resistance state, making them a trusted guardian of RTC.

EPSON Epson nA level RTC RX8111CE

    EPSON's RTC series products, characterized by high reliability, high stability, low power consumption, rich functionality, and miniaturization, are widely used in fields such as the Internet of Things, consumer electronics, and industrial control. RX-8111CE is a real-time clock module newly launched by EPSON, featuring an ultra-low power miniaturized 3225 package.

    Technical parameters: Built in 32.768KHz crystal interface type: IlC bus (supports 400k speed) Ultra low standby power consumption: 100nA Typ@ 3.0V operating voltage, power management function: 1.6V to 5.5V: automatic switching management of main and backup power (supports multiple backup power types) Timestamp function: 8-level timestamp recording depth, multiple optional triggering functions, rich interrupt output: supports Alarm, Update, Timer and other interrupt setting self detection functions: voltage detection, crystal oscillator status detection.

     As a backup power source for RTC, Panasonic button batteries are very popular. The effect of a stable battery will greatly extend the service life of the product.

    The following picture shows the common CR-2032 battery used by Panasonic. In a 20 ° C ambient temperature environment, combined with Epson nA level RTC, it can achieve continuous power supply for more than 15 years, providing stable logistics support for RTC backup power in any situation.

    And the secret to all of this comes from the low internal resistance of Panasonic batteries. Internal resistance refers to the resistance experienced by current passing through a battery. The internal resistance of a battery is an extremely important parameter of a chemical power source, which directly affects the working voltage, working current, output energy, and power of the battery. From the perspective of power and energy output, the smaller the internal resistance of a chemical power source, the better

   The internal resistance of a battery is related to the materials (positive and negative electrode materials, separators, electrolytes, etc.), structure, and assembly process. A good battery should maintain low internal resistance in the later stages of the product to ensure its stability. In addition, Panasonic also has the most stable primary lithium fluoride carbon (BR) battery series in the industry, with a wider temperature range and stronger continuous discharge capacity.
