PANASONIC / BK4LCD2H

Ideal for low-drain devices, this 2-pack of AAA Eneloop Lite NiMH batteries features an upgraded 680mAh minimum capacity for longer-lasting power. With low self-discharge, they retain about 70% of their charge even after 5 years. Operating in extreme temperatures down to -20°C, these reliable batteries are perfect for everyday use and emergency preparedness.

[Features]
■ An easy-to-use model perfect for everyday use
A two-pack of “eneloop light” AA batteries, ideal for devices with relatively low power consumption, such as remote controls and clocks. Compared to the previous model (BK-4LLB), these batteries offer increased capacity, with a minimum capacity of 680 mAh (*1). Furthermore, the number of recharge cycles has increased by approximately 300 (*2), making them more economical and long-lasting.

■Excellent Long-Term Storage Performance—Still Usable After 5 Years
Thanks to proprietary technology that significantly reduces self-discharge, these batteries boast a high capacity retention rate: approximately 85% (*3) after one year and approximately 70% (*3) even after five years when fully charged. They are ideal not only for everyday use but also as part of disaster preparedness kits or as emergency backup batteries.

■Durability That Holds Up Even at -20°C
With a wide operating temperature range from -20°C to 50°C, it offers exceptional low-temperature performance. Its high reliability ensures devices will operate reliably even in harsh environments, such as cold regions during winter.

・An affordable AA “eneloop light” model suitable for devices with low power consumption.
・With a capacity of at least 680 mAh—an increase over previous models—it lasts even longer.
・The number of recharge cycles has increased by approximately 300 compared to previous models.
・Low self-discharge rate; retains approximately 85% of capacity one year after charging and approximately 70% even after five years.
・Excellent low-temperature performance that delivers reliable results even in cold environments as low as -20°C (operating temperature range: -20°C to 50°C).
・A convenient two-pack of AA batteries for everyday use.
*1 Minimum (min.) battery capacity based on the charge/discharge conditions specified in JIS C8708 2019 (7.3.2).
*2 Compared to the previous model, BK-4LLB. Comparison of battery life based on the test conditions specified in JIS C8708 2019 (7.5.1.4). However, the actual number of recharge cycles may vary depending on the device and usage conditions.
*3 Operating time may be shorter depending on storage conditions and the device. In such cases, please charge the batteries before use.
