Bravo Zulu International develops, manufactures, and markets flight simulators and battery restoration devices. Their flagship product, the Model 4800, uses a patent-pending sulfation elimination process to remove lead sulfate buildup from lead-acid batteries through pulse width modulation. This process can restore batteries that would otherwise be discarded, extending their useful life by 2-3 years and saving thousands in replacement costs. Regular treatment is recommended to prevent the more difficult-to-remove Level 3 sulfation and maximize battery performance.
