The Deka® UltraBattery® is virtually 100% recyclable. Each of the three major components (lead, plastic, and acid) can be safely recycled and used in making new energy storage devices.

Lead batteries are the world’s most successfully recycled product because the major component is infinitely recyclable. The lead used to create a battery today will very likely still be in use in a battery hundreds of years from now.

This highly efficient recycling process is driven by the high value of spent batteries. It is economically viable to collect lead batteries and sell them into the recycling chain.


Lead batteries are clean and safe

Adapted from data presented in the SmithBucklin Statistics Group’s “National Recycling Rate Study”, Chicago, Illinois, 2017.


Compare this with most non-lead battery technologies in use today.

  • Very low numbers of non-lead cells are returned for recycling.
  • Much of the material from non-lead batteries that is returned gets incinerated, sent to landfill or processed into low-grade industrial material such as road-bases and additives for steel-smelting or concrete production.*

Sustainability Without Peer

To us, sustainability means that the material inside a battery should, at end of life, be made into a new battery.

We can proudly say that our technology closes the loop.

Since day one, East Penn Manufacturing has made safe recycling an everyday practice. East Penn opened its doors as a battery rebuilding company almost three quarters of a century ago. Today, the company has never stopped building on its expertise, infrastructure, capabilities, and commitment. This continuous commitment has made us the most progressive manufacturer in environmental protection and technologically advanced battery recycler throughout the entire industry.
