What Long-Haul Truck Parking AC Battery Covers
Long-haul trucks idle 20–30 L of diesel per night for cabin AC — ¥40,000–60,000 per truck a year — plus premature engine wear from 500–1,000 idle hours. This page covers PLB's 200Ah LiFePO₄ parking-AC battery: 10 hours of overnight cooling, a one-hour alternator recharge, 2,000+ deep cycles and a three-month payback.

¥200/night, ¥50K/Year Idle Fuel — Has the Fleet Owner Done the Math?
Fleet owners track fuel, tolls, and driver wages — but rarely "idle fuel" as a line item. 20-30L diesel/night at ¥8/L = ¥160–240. 250 days = ¥40–60K/year. A 100-truck fleet's annual idle fuel = ¥4–6M — enough to cover 20-30% of total fleet profit. Critical point: idle fuel never appears on any report because it's buried in total fuel consumption.
Turn hidden costs into visible savings — clear ROI. PLB LL-PC200 at 12.8V 200Ah = 2.56kWh supports 1kW AC for 8–10 hours. Alternator charges full in 1 hour. ¥40K+ annual fuel savings per truck. ¥8–12K investment per truck, 3-month payback. 100-truck fleet saves ¥4M+/year.

100 Idle Hours = 5,000km Extra Wear — Who Pays for Premature Overhaul?
The pain is specific: 100 = 5000 —— 100 Idle Hours = 5,000km Extra Wear — Who Pays for Premature Overhaul? In daily operation, lead-acid or manually managed packs lose capacity between scheduled checks, maintenance teams cannot inspect every unit, and the failure surfaces only when the load is already at risk.
Zero idling = zero wear, overhaul interval extended 50%+. PLB's LiFePO₄ pack and BMS monitor cell voltage, temperature and SOC continuously, alert before a weak cell becomes a failure, and are sized to the application's load profile.
| Conventional / manual | PLB LiFePO₄ | |

| Fault warning | At failure | Threshold alerts |
| Maintenance | Scheduled visits | Exception-based |
| Service life | 2–3 years | 6,000+ cycles |
Lead-Acid Deep-Cycle Dies in 1 Year — Fleets Tired of Constant Replacements
Parking AC discharges 70-80% nightly — classic deep-cycle. Lead-acid deep-cycle life only 300–500 cycles, annual replacement needed. Each set ¥2–3K; 100-truck fleet replacing 100 sets annually = ¥200–300K/year in battery replacement costs. And capacity degrades yearly — 2nd year backup may only be 60% of rated, drivers complain about insufficient AC cooling on summer nights.
One investment, 5 years no replacement — TCO crushes lead-acid. PLB LiFePO₄ 2,000+ deep cycles, 5–8 years at one cycle/day. 100-truck fleet 5-year battery total cost 80%+ lower than lead-acid. ≥80% capacity retention at 5 years — summer AC stays strong, no driver complaints.
| Lead-acid | PLB LiFePO₄ | |
|---|---|---|
| Deep-cycle life | 300–500 cycles | 2,000+ cycles |
| Replacement cycle | 1–2 years | 5–8 years |
| 5-year replacement cost, 100 trucks | ¥1.0–1.5M | One investment |
| Capacity retention | Under 50% | 80% or more |
Solution Advantages
3-Month Payback
¥40,000+ saved per truck a year
2.56kWh supports 8–10 hours of air conditioning and refills in one hour of driving, saving ¥40,000+ a year and paying back in three months — ¥200,000+ over five years.
One-hour refill · ¥40K+ saved a year · ¥200K+ over five yearsZero Wear
Engine fully off while resting
With no idling there is no idle wear: the major overhaul interval extends by 50% or more and annual servicing drops by ¥5,000+.
Oil, filters and decarbonisation saved · ¥5K+ a year · Overhaul 50% later2,000+ Cycles
Five to eight years without replacement
LiFePO₄ delivers 2,000+ deep cycles, so a daily charge and discharge still lasts five to eight years, with five-year TCO more than 80% below lead-acid.
LiFePO₄ · 80%+ capacity at five years · Lowest TCOFast Charge
One hour from the alternator
Charge acceptance is three to five times that of lead-acid, so an hour of driving brings the pack to full without disturbing the operating schedule.

Frequently Asked Questions
The questions fleet managers and truck owners ask most about LiFePO₄ parking-AC batteries in the Long-Haul Trucks scenario — ¥40,000+ (saved per truck / year) and 3 months (payback), and what it takes to qualify.
What has to change on the vehicle before a LiFePO₄ pack goes into the Long-Haul Trucks scenario?
The pack fits the original battery box at the same 12 V or 24 V system voltage with the same terminal layout, so no bodywork change is needed. Typical models for Long-Haul Trucks builds are LL-PC200 and LL-PC250.
Does output stay flat through a whole Long-Haul Trucks rest period?
The pack runs the air conditioner through the rest period without idling the engine, and deep-cycle life replaces the one-year lead-acid replacement cycle.
How is the pack sealed and thermally managed in Long-Haul Trucks duty?
The sealed pack is rated for engine-bay heat and road vibration, with BMS protection against over-current and over-temperature. Endurance: ¥40,000+ (saved per truck / year).
Is a special charger needed in the Long-Haul Trucks scenario?
The alternator recharges the pack while driving, and the BMS limits current so the vehicle circuit stays inside its rating.
What warranty and after-sales support apply in the Long-Haul Trucks scenario?
Standard products carry a full warranty backed by lifetime technical support, with terms confirmed on the quotation; export packing is UN 38.3-certified with MSDS. Tell us the air-conditioner rating, nightly hours and battery-box dimensions — our engineers size the pack and recommend the matching model within 24 hours.
Need a Selection Recommendation?
Tell us the load, backup time and installation space — our engineers will recommend the matching battery within 24 hours.
