What City Delivery Truck Parking AC Battery Covers
Unique conditions: 20-50 frequent start-stops daily, 1–2 hour lunch break AC, evening waiting with AC. Short but frequent parking kills lead-acid with daily shallow cycling sulfation — 30-40% capacity loss within 1 year. Fleet managers frustrated by "replace every year, capacity drops every year." PLB, founded 2014, light truck parking LiFePO₄: compact installation (1/3 lead-acid volume) + fast alternator charging (30-min driving recharges), 150Ah supports 2-hour cooling. No sulfation, 5–8 year life. ¥8K+ annual idle fuel savings.

+ —— Lunch Break + Evening Wait — Hidden Idle Fuel Costs Fleets Don't See
Light trucks run AC during 1–2 hour lunch + 1–3 hours evening wait. Short per session but daily — 3-5L/hour idle, 600-1,500L/year = ¥5–12K. 100-truck fleet idle fuel ¥500K-1.2M/year. Buried in total fuel cost — fleet managers never see it. But switch to parking battery and it becomes visible pure profit.
Turn hidden costs into visible profit. PLB LL-PC150 at 12.8V 150Ah = 1.92kWh supports 1kW AC for ~2 hours. Stop engine before lunch, battery-powered AC — quiet cooling. Afternoon delivery alternator recharges within 1–2 hours. ¥8K+ annual savings per truck; 100 trucks = ¥800K+ annual savings.

|---|---|---|
| Daily idle fuel | 3–5 liters | Zero |
| Annual fuel cost per truck | ¥5,000–12,000 | ¥0 |
| Annual cost, 100 trucks | ¥500,000–1.2M | ¥800,000+ saved |

—— 1/3 Light Truck Battery Compartment Too Small — PLB 1/3 Volume, No Modification
The pain is specific: —— 1/3 Light Truck Battery Compartment Too Small — PLB 1/3 Volume, No Modification 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 modification cost — direct drop-in replacement. 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 | |
|---|---|---|
| Monitoring | Periodic checks | Continuous BMS |
| Fault warning | At failure | Threshold alerts |
| Maintenance | Scheduled visits | Exception-based |
| Service life | 2–3 years | 6,000+ cycles |
Shallow Cycling Sulfation Kills Lead-Acid in 1 Year — How Many More Years?
Light trucks use parking AC in multiple short sessions daily. Frequent shallow cycling causes irreversible plate sulfation. Within 1 year, 30-40% capacity lost. This is why light truck parking lead-acid batteries die young — not from heavy use, but from "fragmented" use. Shallow cycling is lead-acid's worst enemy.
LiFePO₄ is immune to shallow cycling — no sulfation. PLB 2,000+ cycles unaffected by shallow cycling, <5% annual capacity loss (vs lead-acid 30-40%). BMS auto-balances each cell. 5–8 year life — from "replace yearly" to "install and forget."
| Lead-acid | PLB LiFePO₄ | |
|---|---|---|
| Shallow-cycling effect | Accelerated sulphation | None |
| One-year capacity loss | 30–40% | Under 5% |
| Actual life | 1–2 years | 5–8 years |
| 5-year battery cost, 100 trucks | ¥1.0–1.5M | One investment |
Solution Advantages
Compact Fit
One third the volume, drop-in replacement
The 15L case is about a third of a lead-acid 150Ah battery and replaces it in the factory battery box with no modification cost and no effect on annual inspection.
15L compact case · Original position · Zero fitment costFast Charge
Full within a 30-minute delivery window
Charge acceptance is three to five times that of lead-acid, so a one to two hour generator window between deliveries is enough without disturbing the schedule.
3–5× lead-acid speed · Topped up between deliveries · No schedule impactNo Sulphation
Built for shallow cycling
LiFePO₄ has no sulphation mechanism, so frequent shallow cycling does not degrade capacity: under 5% loss in year one and a five to eight year life.
LiFePO₄ has no sulphation · Under 5% loss in year one · 5–8 yearsAnnual Savings
¥8,000+ saved per truck
Idle fuel disappears entirely during breaks and while waiting for loads, paying the investment back in three months and earning afterwards — with quiet, vibration-free cooling.
Zero idle during breaks and waiting · 3-month payback · Quiet coolingFrom Selection to After-Sales — PLB Stays With You

Frequently Asked Questions
The questions fleet managers and truck owners ask most about LiFePO₄ parking-AC batteries in the City Delivery Trucks scenario — ¥8,000+ (saved per truck / year), and what it takes to qualify.
What has to change on the vehicle before a LiFePO₄ pack goes into the City Delivery 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 City Delivery Trucks builds are LL-PC150.
Does output stay flat through a whole City Delivery 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 City Delivery Trucks duty?
The sealed pack is rated for engine-bay heat and road vibration, with BMS protection against over-current and over-temperature. Endurance: ¥8,000+ (saved per truck / year).
Is a special charger needed in the City Delivery 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 City Delivery 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.
