What Construction Machinery Battery Covers
Global market exceeds $200B — equipment utilization directly determines project profit. Lead-acid lasts under 2 years — replacement costs ¥1,500–2,000/year plus downtime ¥2,000–5,000/day. Breaker hammer vibration exceeds 5G; lead-acid plate cracking is common, potentially causing internal short circuits. Contractors and rental companies are doing the math: lead-acid 3 replacements in 3 years + downtime vs lithium one-time investment 5 years zero failures — TCO gap far exceeds initial price difference.
Professional Battery Solutions
Downtime ¥2,000–5,000/Day — What's the Cost of Battery Failure?
Excavators/loaders use 24V systems with 500–1000A cranking. Lead-acid CCA drops from ~600A to below 400A in 6 months. Each equipment experiences 1-2 battery failures/year, each costing ¥2,000–5,000 in downtime. 100-unit fleet: annual battery-related downtime loss easily exceeds ¥1 million.
5 years zero downtime; save ¥1M+ per 100-unit fleet. CCA up to 800A, 1000A+ pulse discharge, no degradation — start #1 and #50 equally powerful. Military-grade sealed structure: 5,000+ hours breaker hammer test, zero performance change. CCA.
| Lead-acid | PLB construction | |
|---|---|---|
| Downtime cost | ¥2,000–5,000 a day | Removed |
| Starting reliability | Frequent failures | First time, every time |
| Continuous starting | Voltage collapses | No degradation |
| First start versus fiftieth | Noticeably weaker | Identical |
-35 °C Extreme Cold Start — No More Construction Delays
The pain is specific: -35 °C Extreme Cold Start — No More Construction Delays 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 annual delay losses; no more battery wrapping. 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.

| Fault warning | At failure | Threshold alerts |
| Maintenance | Scheduled visits | Exception-based |

+ + IP67 Mud + Oil + Cement Slurry — IP67 Full Protection
Extremely harsh environments: excavators in mud, loaders in dust, concrete pumps in cement slurry. Lead-acid housing and terminals corrode quickly, causing poor contact and failed starts. Annual cleaning or replacement needed.
Zero annual maintenance. IP67 rated (short-term submersible). Hydrophobic oil-repellent coating — rinse clean. Gold-plated terminals + sealed silicone. Field tested: after mud, hydraulic oil, cement contamination — appearance and function intact after cleaning.

| Oil and slurry | Not cleanable | Hose-down clean |
| Terminal protection | None | Oleophobic coating |

Frequently Asked Questions
The questions vehicle OEM engineers and fleet managers ask most about LiFePO₄ starting batteries in the Construction Machinery scenario — 5,000 h (breaker vibration), and what it takes to qualify.
Which pack fits the Construction Machinery vehicle already in service?
The pack keeps the 12 V footprint, terminal orientation and charge window of the lead-acid battery it replaces, so the vehicle harness needs no rework. For Construction Machinery builds the range starts at AUTO-100CE and AUTO-120CE, specified at >80% (capacity at −30 °C).
How much usable capacity does the pack deliver across a drive cycle in Construction Machinery service?
Cranking output stays flat across the usable SOC window, and the pack is rated for 2,000+ start-stop cycles instead of the few hundred a lead-acid auxiliary battery survives.
Will the pack survive Construction Machinery conditions for its full service life?
Specification: 5,000 h (breaker vibration). The BMS protects the pack against over-current, over-temperature and deep discharge across the vehicle range.
How does the pack connect to the charger and control system in the Construction Machinery scenario?
CAN 2.0B or LIN 2.1 integration with an open DBC file covers VCU communication, and the BMS reports SOC, voltage, current and temperature.
Can the pack be customized for the Construction Machinery application and certification file?
Cells, BMS, housing, terminals and nameplate are customizable. Custom packs take 4–8 weeks including tooling. Tell us the vehicle model, engine size and target SOP date — our engineers size the battery and quote within 24 hours.
