Newmar The NewMar NS-12-20 StartGuard power conditioner is an internal battery that supplies supplemental power to mobile equipment during engine crank to prevent memory dump and loss of data. The sealed internal rechargeable battery is switched online whenever the starter switch is engaged. This delay timer will automatically go offline and begin recharging internal battery when the engine is running and voltage system returns to normal. The NewMar StartGuard supplies 20 amp power maximum based on 12V DC. Typical life is 5 to 7 years.

The abrupt DC system voltage drop that accompanies engine starting can cause microprocessor-driven communication and navigation electronics to dump programmed memory. StartGuard solves this problem by providing supplemental voltage to sensitive electronics while the engine is cranked. It contains a sealed rechargeable battery which is switched on-line to electronics when the starter switch or solenoid is engaged. When the engine is running StartGuard automatically goes off-line and the internal battery is recharged by the alternator.
