Cole Hersee’s SureStart automatic low-voltage disconnect (LVD) allows vehicles to start even if they’ve been left standing for weeks or are stopped and started many times a day. The LVD is a smart electronic switch that senses battery voltage and conserves starting power. When the battery voltage falls below the threshold, it automatically disconnects noncritical loads and automatically reconnects them when the batteries are being charged. A built-in “snooze timer” allows the operator a one-hour override of the function. Available in 100 A, 150 A, and 200 A configurations at 12-v dc, the SureStart LVD also prolongs battery life by preventing damage caused by overcranking of a low battery.
