Operating flawlessly in extreme temperatures from -20°C to 50°C, these classic rechargeable batteries are a highly reliable choice for everyday devices and emergency preparedness.

[Features]
■ A Standard Model with Even Longer Life
Compared to the previous model (BK-4MCC), the battery capacity has been increased, achieving a minimum capacity of 800 mAh (*1). This extremely user-friendly standard model provides stable power over the long term to a wide range of everyday devices, including wireless devices, audio remote controls, and portable electronics.

■ Excellent Long-Term Storage Performance—Ready to Use Even After 10 Years
Panasonic’s proprietary discharge suppression technology significantly reduces self-discharge. When fully charged and stored at room temperature (20°C), it boasts an astonishing capacity retention rate of approximately 90% (*2) after one year and approximately 70% (*2) even after 10 years. It demonstrates extremely high reliability not only for everyday rotational use but also as a backup battery for disaster preparedness kits and emergency evacuation bags.

■ Durability Proven Even in Extreme Cold Down to -20°C
With an extremely wide operating temperature range from -20°C to 50°C, these batteries feature excellent low-temperature performance capable of withstanding harsh temperature fluctuations. Even in demanding environments such as outdoor winter events or cold regions, they are resistant to voltage drop, ensuring connected devices operate reliably.
