The PulseTech PowerPulse PP48L is not a charger. This onboard device utilizes revolutionary ReNew-IT Pulse Technology™ to safely prevent the main cause of battery problems and failure: sulfation. Over time, the chemical reation of lead acid batteries, force sulfates to leave their liquid state, adhere to and build up on the lead battery plates. This build-up of sulfur inhibits the electrolyte from reacting with the plates and slowly kills your battery. The phrase my battery never seems to have the power it used to! is a common remark, that does not need to be uttered when you use a Power Pulse onboard desulfator. The PP-48-L will prevent sulfation from occurring and can even reverse the effects and recondition batteries that have become sulfated. Selected as a Top 50 Product by Automotive Engineering magazine, the 48-Volt PowerPulse is designed to ensure maximum battery performance 48-volt lead-acid battery systems. It also works on two or three small 48-volt battery systems connected in parallel. The PP48-L is ideal for virtually any kind of vehicle or equipment that is charged on a regular basis, including golf carts, commercial electric vehicles, forklifts, boats, and much more. It comes with 3/8 lugs that connect directly to the battery terminals.
