The 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-acid 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-acid batteries and sell them into the recycling chain.


Lead-acid 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-acid battery technologies in use today.

  • Very low numbers of non-lead-acid cells are returned for recycling.
  • Most of the material from non-lead-acid batteries that is returned gets incinerated or processed into low-grade industrial material such as road-bases or concrete additives.

Sustainability Without Peer

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

Essentially, 100 percent of each UltraBattery is returned for recycling. And, once returned, 96 percent by mass of the battery is reused to make a new battery. The other 4 percent is used for agricultural and industrial purposes. Next to nothing is wasted. Next to nothing reaches the environment.

We can proudly say that our technology closes the loop.

Since day one, our manufacturer and parent company, 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.
