Why Choose Lithium D Cell Batteries?

Memory Effect-Free Battery

Unlike alkaline, Ni-MH, and Ni-CD batteries, the lithium D cell features no memory effect. This means the battery capacity won't decrease over time, ensuring longer-lasting performance.

Eco-Friendly and Longer Lifespan

Lithium D cells are more environmentally friendly and have a longer life. They maintain up to 75% of their capacity even after three years of non-use due to their improved low self-discharge function.

Easy and Efficient USB Charging

Whether you're camping or at home, simply charge the batteries using a single USB port. They offer up to 2,000 charging cycles, eliminating the need to frequently buy new batteries.

Fast Charging

Full charging takes only 3-5 hours. The LED indicator turns red when charging and green once fully charged, providing you with convenience and efficiency.
