Dead Batteries in Stored Equipment? Try This Solar-Fueled Solution


No doubt, you store many pieces of equipment outdoors for long stretches during their “off season,” including generators, vehicles, and other machinery powered by batteries. When it’s time to roll again, dead batteries caused by the normal buildup of lead sulfate crystals could slow you down.

PulseTech provides a solution in its military-grade, 24-volt Solar Pulse charging system. It charges, maintains, and de-sulfates equipment powered by 24-volt lead acid battery systems — including standard, AGM, and gel types.

According to the company, Solar Pulse is a sturdy 6.3-watt solar panel that provides power to charge the battery system and keep buildup at bay. The panel is 9 inches wide, 11.4 inches long, and 2.5 inches thick. It weighs 4.75 pounds. (PulseTech’s solar panels have higher efficiency and higher-quality crystalline silicone cells that pack more power per square inch and have a longer life than standard amorphous “thin film” solar cells. This is what allows for a sturdier, smaller-sized solar panel.)

You can tell Solar Pulse is working by a quick glance at the LED indicators.

When the green LED is flashing, the battery is being charged, and when the green LED is steadily on, the battery is fully charged. During and after the charge cycle, the solar panel also supplies energy to the optimized pulse technology circuit to reverse the buildup of energy-robbing sulfate deposits on the battery plates, the main cause of battery failure. The flashing red LED indicates that the battery is being pulsed.

If no batteries are connected, the battery connection is faulty, or the battery or battery system is measuring less than 22 volts, the red monitor LED will remain steadily on, telling you to check the battery connection.

The system works on all kinds of 24-volt lead acid batteries and 24-volt battery systems, and comes with a one-year limited warranty. For more information, go to The part number is 735X687.
