VEE System and HD648 System, both employ a Patented Dual Pulse Algorithm inducing a total of 10,600 pulses per second into the battery. The first 5300 pulses of current per second are extracted from the battery after which the finely tuned Pulse Wave is created and induced back into the battery  at the same rate of 5300 per second. This highly efficient dual action targets crystallized inactive material at its resonant frequency, re-energizing it back into active service leaving the battery in as new condition. The high frequency and high intensity bi-directional pulses act as a Pace-Maker for the battery and the electrical system, restoring efficiency and reliability. VEES and HD648 use only 10mA of power which is derived from the battery, therefore no external power input is required. VEES conditions up to 1500Ah of battery capacity, while HD648 conditions up to 2000Ah of battery capacity. For battery banks of higher voltage or capacity, multiple units can be installed in series configuration to service banks of any voltage and capacity.
