For the regeneration of automotive and Caddy batteries. The battery pulser is patented and is ideally connected to the vehicle battery as a preventive measure. The impulses generated when the alternator is charging prevent or reduce the typical aging sulfation of the battery. This can increase the battery life 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 regain significant starting power and capacity with such treatment and can be reinstalled in the vehicle. There are limitations to its effectiveness with batteries that have a mechanical defect or a cell short circuit. Installation should be near the battery and preferably splash-proof.
