The KSM™ assures you will never experience a "no-start" from a dead battery again. It’s a supercapacitor, and when it is installed in a boat, downtime from a dead battery is completely eliminated.
The device is initially energized from the boat’s electrical system and stores the energy until needed. Even with a rundown battery, the KSM™ provides an engine the power it needs to start. It is virtually unaffected by temperatures and is completely maintenance free.
KSM™ has a long service life, with upwards of one million cycles without the loss of cranking power, compared to an average battery’s life of 300 – 500 cycles. It often outlasts the equipment it is installed in. Thousands of units are in service and have been operating effectively for many years. KSM™ is 100% maintenance free, so you don't have to access it until you move it to your next boat.
