Legends Business Group Inc. announced the Restorer Chargers (RC) has been undergoing performance testing over the last several weeks. Testing has been completed by a third party testing facility and they have submitted their preliminary testing report for review. The company disclosed the performance testing results on the company's second product, the Restorer Chargers (RC); to be added to the upcoming Zombie Chargers product line.

On November 15, 2012, the company announced it had authorized their main manufacturer to research and obtain a third party testing facility thus keeping the company at arm's length of the testing. The Restore Charger's performance test was expected to verify the claim that the Zombie Battery Restorer is capable of reconditioning common discarded lead-acid batteries used mostly in the automotive industry. The RC is designed to recover 12 V lead acid batteries ranging from 4 Ah in capacity and above.

The RC's primary function is to restore mostly older, non-functioning batteries, which will no longer take a charge using the standard chargers available on the market. Using proprietary programming and pulse-charging techniques, this technology is claimed to overcome several of the limitations of existing technologies; the inability to reverse the negative effects of early failure due to sulfation on a battery's plates and thus the inability of restoring a battery to a like new status. Based on the results of this investigation, the data shows significant improvement in the capacity of restored lead-acid batteries after being subjected to the Restore Charger.

Overall, the findings showed that eight out of the ten batteries taken directly from the junkyard that were restored and tested, passed a final load test with cold cranking amperage ratings, which were at or above the manufactures represented value on the battery. While it is outside of the scope of this investigation to determine the long-term effects of the Zombie Restorer on the test batteries, a qualitative third load test, conducted about two weeks later, showed that the batteries still retained a substantial quantity of their charge, and continued to give acceptable cold cranking amperage values.
