The battery pulser is patented and is ideally connected to the vehicle battery as a preventive measure. The pulses generated when the alternator is charging prevent or reduce the typical aging sulfate buildup in the battery, which is the cause of failure in 80% of cases. This can extend the battery's lifespan by up to five times. Megapulse can also be used for battery maintenance in conjunction with a battery charger or maintenance device. Even old batteries can significantly regain starting power and capacity with such treatment and can be reinstalled in the vehicle. There are limitations to its effectiveness for batteries that have a mechanical defect or a cell short circuit. Installation should be done near the battery and preferably in a splash-proof manner.
