The ComfortPro® electric auxiliary power unit (APU) with li-ion batteries (250ION) significantly outperforms conventional electric APU runtime and battery life, providing quiet, emissions-free performance with minimal maintenance. Using proprietary power-management technology, two li-ion batteries do more than the work of four AGM batteries, achieving 17 hours of continuous air conditioning under certain real-world conditions, the longest of any electric APU. That’s double the runtime of some competitive models and 50% more runtime than our AGM-battery model, while trimming APU weight by 26%.
ComfortPro Lithium-Ion Battery Powered APU



- Purpose-built Batteries: Advanced li-ion batteries are engineered specifically for
APU applications. An extremely power-dense and durable solution, they charge faster
and experience less power degradation over time compared to conventional batteries.
Warrantied for worry-free performance for five years, outlasting some fleet trade cycles. - Fuel Savings: Fuel savings and compliance with anti-idling regulations are immediate
as soon as the truck engine is shut off and the ComfortPro electric APU is turned on. - Low Maintenance System: With few moving parts compared to diesel APUs,
ComfortPro electric APUs minimize maintenance expenses. - Faster ROI: Compared to a diesel APU, the li-ion ComfortPro electric APU has a
lower total cost of ownership resulting in faster ROI.
