Parking AC / Auxiliary Power
Power for Trucks That Sleep on Their Own Battery
Anti-idling regulations have made electric parking air-conditioners standard equipment on long-haul trucks worldwide. Conventional starting batteries fail in 90 days under this duty. We built a battery that survives 600+ deep discharge cycles and still cranks a cold diesel the next morning.
The Parking AC Duty Cycle Problem
A typical electric truck parking AC consumes 30–45 amps for 8–10 hours overnight — that's 300–450Ah of energy, every single night. Standard SLI batteries are designed for 5% surface discharges. They're dead in 90 days. The Obsidian Pro series is engineered specifically for this dual-duty: deep cycling endurance plus high-CCA cranking, in one battery.
Built for Parking AC
Engineered to survive 600+ deep discharges to 80% DoD. Standard MF batteries die in <90 days under the same duty cycle.
Dual-Purpose Cranking
Still delivers 1000+ CCA at -18°C the next morning. No need for a separate starting battery — one battery handles both jobs.
Heavy-Truck Vibration
Reinforced grid alloy and triple-anchor hold-down. Survives 24/7 hull pounding and engine vibration of long-haul service.
Anti-Idling Compliant
Enables compliance with US, EU, and Chinese anti-idling regulations. Reduces fuel waste and engine wear from overnight idling.
