1. Logistics Fleet Reduces Downtime by Replacing Key Battery Wear Parts

A regional logistics fleet operating 180 electric forklifts reported frequent lead-aicd battery issues after 18 months of heavy use. Problems included shorter runtime, voltage drops, electrolyte leakage, and corroded terminals. The maintenance team spent hours daily refilling water and replacing worn parts, while unexpected failures disrupted peak-hour deliveries.

To address the issue, the fleet replaced aged vent plugs, faulty automatic watering system components, corroded battery cables, loose pole bolts,with high-quality, compatible parts. After the upgrade, daily maintenance time was cut by over 60%, electrolyte leakage was eliminated, and battery runtime stabilized. The fleet also reduced unexpected downtime and extended overall battery service life.

2. Essential Battery Parts

Vent plugs degrade over time from vibration, high heat and chemical corrosion, losing sealing ability. This causes electrolyte leakage, water loss, poor pressure control and blocked gas release, raising risks of battery swelling and safety incidents.

Maintenance Tips: Power off the battery before refilling. Use only distilled water and maintain standard liquid levels. Wear protective gear and tighten vents firmly after use. Regular replacement guarantees reliable sealing, gas discharge and stable battery performance.

Our high-performance vent plugs and automatic watering systems are engineered for lead-acid batteries. We support OEM for domestic and global forklift battery makers, with fast delivery and long warranty.

Long-term use will wear down automatic watering systems. High temperatures and chemical Long-term use, high temperatures and chemical corrosion clog and age internal pipes and valves, resulting in inaccurate water supply, system breakdown and liquid overflow. Timely replacement stabilizes water supply, reduces manual upkeep and extends battery life.

Our automatic watering systems refill water automatically when liquid levels drop to the preset value. They eliminate frequent manual refilling, prevent electrolyte leakage and lower daily maintenance work.

Vibration, high temperature and oxidation damage cables and terminals over time, leading to poor contact, rising resistance, overheating and power failure. Regular replacement ensures safe, steady power transmission.

At ProLaker, we specialize in manufacturing premium cables for lead-acid batteries. We offer a full range of models to perfectly match various batteries. Our products adopt high-quality copper cores and galvanized connectors, delivering outstanding corrosion resistance.

Battery bolts gradually rust and loosen under long-term vibration and humid environment. Loose or corroded bolts lead to poor contact, excessive heat generation and even circuit faults. Regular replacement ensures firm connection and safe operation of the battery.

Our battery connector bolts are made of high-strength steel for heavy-duty industrial use. Boasting great durability and corrosion resistance, they secure stable connections in warehouses, construction sites and other harsh working conditions.

3. Industry Summary & Future Outlook

In general,battery cables, bolts, vent plugs and circuit components are universal vulnerable parts for all forklift batteries. The selection of spare parts depends on factory positioning, battery connection structures and battery technologies.

Driven by energy conservation and emission reduction policies, lithium-ion batteries will gain larger market share, which will drive up the demand for high-voltage connecting cables. Meanwhile, the huge stock of lead-acid batteries will maintain steady market demand for vent plugs, automatic watering systems,battery cables and bolts.

For logistics and manufacturing enterprises, using high-quality spare parts and conducting regular maintenance can reduce equipment failure rates and operating costs. For parts suppliers, battery manufacturers and repair service providers, improving product quality and enriching product ranges is the key to seizing market opportunities and achieving long-term development.We provide a full range of reliable forklift battery accessories with complete specifications.
