Dantona DL-40 6V 2200 mAh alkaline standard battery

Direct replacement for Interstate DRY0048

The Dantona DL-40 is a 6V alkaline battery rated at 2200 mAh. It is built as a direct replacement for the Interstate DRY0048 door lock cell. Security installers and facility managers use it to keep electronic locks powered without rewiring.

Swaps the original cell when voltage drops

This unit replaces the factory fitted battery once its output falls below the lock’s operating threshold. The change is worth it when the existing cell no longer holds enough charge for reliable daily cycles. No adapter or harness modification is required.

Steady output through repeated lock cycles

Alkaline chemistry delivers consistent voltage across each activation rather than a short burst. The 2200 mAh capacity supports extended operation between replacements, reducing maintenance visits on high traffic doors. Performance remains stable until the cell approaches end of life.
