PulseTech SolarPulse Solar Battery Charger and Maintainer These uniquely designed solar panels are made of highly efficient proven crystalline silicon photovoltaic cells, encapsulated with a clear polyurethane plastic coating (instead of a breakable glass coating), and mounted on a laminated aluminum substrate back plate that is less than 1/4” thick. This makes the panel virtually indestructible, impervious to weather and resistant to damage. If you’ve used solar chargers before, you know it’s important to choose the right solar panel for the amount of power you need and the size and place of the mounting location. In the past to get the power you needed, you had to struggle with panels that were too big, too bulky and too fragile. PulseTech’s higher efficiency, higher quality crystalline silicone cells pack more power per square inch and have a longer life than standard amorphous “thin film” cells. That means you can get the power you need in a sturdier, smaller-sized solar panel. PulseTech SolarPulse chargers maintain the battery power on seldom-used vehicles and equipment stored outdoors, ensuring batteries are maintained indefinitely without the risk of overcharging or overheating. The solar panel replaces the power loss from electrical accessories that occurs even when the ignition is switched off and PulseTech’s patented Pulse Technology reverses the damaging effects of naturally occurring sulfates. An LED light indicates charge so you know when it’s working. The LED shines brightly when the solar panel is in full sunlight and working at optimum level, dims when the panel is exposed to partial sunlight and goes out at night. Chargers are reverse polarity protected and compatible with all 12-volt lead-acid batteries, including VRLA, AGM, gel, and flooded cell types. Kits include: Low-profile solar panel with quick disconnect leads; Circuit Box housing our exclusive Pulse Technology; Positive and Negative Lugs for connecting to the battery. Restore Your Battery to Peak Performance! Powered by PulseTech’s patented Pulse Technology, this advanced battery repair mode uses cutting-edge Pulse Technology to deliver 25,000 cycles per second, pulsing and effectively eliminating harmful lead sulfate crystals on the battery plates and detecting battery sulfation. This process restores battery health, ensuring stronger engine starts and extending battery life by up to 3 times!
