Battery X Metals Inc., a company at the forefront of energy transition exploration and technology, has announced a significant breakthrough in electric vehicle (EV) battery restoration. Through its subsidiary, Battery X Rebalancing Technologies Inc., the company has successfully achieved full capacity recovery in a retired 96-cell Nissan Leaf battery pack using its second-generation, patent-pending lithium-ion battery rebalancing machine, Prototype 2.0.
The trial, conducted in collaboration with Factor E Motors, involved a real-world Nissan Leaf battery composed of lithium manganese oxide (LMO) and lithium nickel oxide (LNO) cells. The battery, previously measured at 50.34 ampere-hours (Ah), showed a capacity recovery of 1.95 Ah, translating to a 3.9% improvement after the rebalancing process. All 96 cells were successfully aligned to the industry-standard voltage target of 4.20 volts, resulting in a post-rebalancing effective capacity of 52.29 Ah.
“This trial marks a significant milestone in validating our rebalancing technology under real-world conditions,” said Massimo Bellini Bressi, CEO of Battery X Metals. “Even with a relatively well-balanced battery pack, the recovery of nearly 2 ampere-hours highlights the precision and power of our rebalancing solution.”
Prototype 2.0 uses a unique approach, applying individualized currents of up to 3 amperes to bring each cell to the optimal voltage level. The results confirmed 100% recovery of the imbalance-related lost capacity based on data from the Battery Vendor Diagnostic Report.
To further validate the findings, Battery X Rebalancing Technologies plans to conduct a complete charge/discharge cycle, identify any defective cells, and refine its standard operating procedures (SOPs). The trial also supports the company’s broader initiative to enhance EV battery longevity, reduce waste, and support the circular economy of electric mobility.
The trial was conducted on a Nissan Leaf battery purchased for $1,120 from a third-party vendor. The Leaf, being the second most common out-of-warranty EV in the U.S., serves as a critical testbed for the rebalancing platform’s market potential.
Following its earlier partnership with Factor E Motors, focused on Tesla battery packs, Battery X is now accelerating development for diverse EV battery chemistries and configurations. The company believes its rebalancing technology could reduce costly replacements and help extend the lifespan of high-volume EVs nearing or past their original warranties.
As Battery X prepares for broader deployment, the latest results solidify the commercial and environmental promise of its proprietary rebalancing technology, opening new opportunities in EV maintenance and battery lifecycle management.
