Extended Battery Life - PulseTech uses patented technology to break down sulfation crystals back into the solution of vehicle batteries allowing them to recover, charge deeper and last up to 3x longer! A longer battery life reduces recycling and pollution, making our planet a better place to live. Our unique Pulse Technology has been independently tested by Ohio State University and proven to recover and extend the battery life of 12-volt lead-acid batteries. The XC400 evaluates the battery during initial connection and tests it continually to determine the appropriate charge rate based on your battery’s current capacity and condition. This TEST step also includes a “Bad Battery” indication if it determines the battery is faulty and cannot be re-charged. Pulse conditioning provided by PulseTech Products increases performance and life cycles of any size or type of 12V lead-acid battery. Ultra Safe - Fuse-protected, spark-proof, and water-resistant battery charger. No overheating or overcharging no matter how long the battery maintainer is connected. Advanced Design - 4-amp battery charger features Pulse Technology. Most battery chargers say their “pulse” loads batteries with a higher voltage charge to break off sulfation in larger pieces allowing amp hours to return to normal. This sulfation collects at the bottom, causing an arc of power to transfer from one plate to another shorting the cell. Our Pulse Technology breaks down sulfation crystals into the solution of vehicle batteries allowing the battery to recover and charge deeper. In the box - The XC400 battery maintenance charger features a rugged plastic protective case. It comes with an eyelet lead and clip lead. Five-Year Limited Warranty. Versatile Use: The XC400 battery charger and maintainer is perfect for all land or water vehicles like RVs, outdoor equipment, small boats or watercraft, and automobiles. PulseTech is an American company with a team of customer service technicians to answer any questions you may have. PulseTech’s PULSE technology - a high frequency conditioning pulse recognized to effectively charge and recover weak 12V batteries. This fuse-protected, spark-proof battery desulfator reduces naturally occurring sulfation which increases performance and makes vehicle batteries last up to 3 times longer without ever overheating or overcharging. Proprietary algorithms, combined with microprocessor-controlled technology, measure the battery's voltage and current to automatically determine the battery's state of charge (25%, 50%, 75% or 100%) and deliver the precise charge rate based on the size and condition of the battery. No guess work!
