Nowadays, Deka has its one-stop production facility in Berks County, PA. The production plant is one of the world’s largest, covering around 520 acres. 

This massive production facility has helped Deka to streamline its production greatly. Also, their actual research and development section is established within the 520 acres of premises. Apart from the batteries, Deka also produces automobile wiring in this production facility. 

Nonetheless, that’s not all. The 520 acres of manufacturing also include a large recycling and smelting facility within the premises. There Deka recycles their old batteries as part of their conservation promise for the environment and eco-friendly production. Their recycling includes:
