IdlePro Extreme Delivers Serious Power, Even at Idle 

The core benefit of the IdlePro 24V alternator is right there in the name, IdlePro.

Buses spend a lot of time idling. For city traffic and bus stops, pre-trip checks and shift changes, performance at idle matters. Low-speed running is a killer for most alternators, leading to undercharged batteries and shorter battery life.

Prestolite IdlePro alternators are engineered to deliver a minimum of 70% of their rated maximum output at engine idle. 

Both IdlePro models feature a high-amp, high-efficiency design. 

  • Swing Mount IdlePro, 180-AMP: AVI150S1111HP
  • Pad Mount IdlePro, 180-AMP: AVI150P1120HP

This is a game-changer. It’s like having a top-tier athlete who can run at 70% of their maximum speed while resting. This consistent power output, even when the engine is barely turning, translates directly into efficient, battery-saving performance.

IdlePro Alternators Set the Engineering Standard

IdleProTM alternators put out power and are built to last. When it comes to something as crucial as your charging system, you need a solution that is both reliable and cost-effective.

The IdlePro incorporates several features that address the realities of a heavy-duty operating environment.

Three IdlePro features that set the standard include:

  • Dual Internal Fan Design: Heat is the enemy of electronics, and this design is a strong defense against it. The dual-fan setup maintains optimal bearing temperatures and minimizes heat-related damage, which means a longer service life for the unit. 
  • Premium eCoated Heavy Duty Housing: The housing offers superior corrosion resistance and improved durability, crucial for vehicles exposed to road grime, salt, and extreme weather.
  • Remote Sense Capable: For purchasing managers, this feature is a silent budget-saver. The remote-sensing capability reduces battery charging time, ensuring the battery returns to a full state of charge quickly between vehicle stops. This optimization is key to maximizing battery lifespan.
