CLARK FUSION Lithium-Ion-Technology for forklift trucks and warehouse technology

CLARK FUSION lithium-ion batteries

With CLARK FUSION lithium-ion batteries, CLARK offers a modern, high-performance energy storage solution specifically developed and optimised for CLARK electric forklift trucks. The result is higher day-to-day availability, reduced battery management effort and a future-ready technology for your forklift fleet.

Whether you are a logistics manager, procurement manager or fleet manager, you benefit from a combination of high productivity, lower operating costs and efficient energy use. The CLARK FUSION lithium-ion battery is seamlessly integrated into selected CLARK electric forklift truck models, supporting a smooth and reliable transition to lithium-ion technology.

Below, you can find out which CLARK models are available with this technology and what tangible benefits it offers in terms of charging times, maintenance requirements, efficiency and total cost of ownership (TCO).

Flexible charging: one charger for 48 V and 80 V systems

With the introduction of the CLARK FUSION battery, CLARK also presents a new multi-voltage charger capable of charging both 48-volt and 80-volt batteries. This universal lithium-ion charger features a robust design, including a metal housing with wall-mount option, and a clearly visible LED display indicating the battery’s charging status.

This solution is particularly practical for mixed forklift fleets. A single charger can now be used to charge all CLARK electric counterbalance forklift trucks equipped with FUSION lithium-ion batteries – from the compact 48 V models STE16-20 and SE16-20 to the larger 80 V series SE25-35, L25-35XE, S25-35XE and GEX40-50.
For operators, this means fewer different chargers in use, a simplified charging infrastructure and greater operational flexibility. Decentralised charging points can be installed close to the point of use, as ventilated charging rooms are no longer required. Drivers can conveniently charge forklift trucks exactly where they are needed – ensuring maximum efficiency.

Fast charging and opportunity charging for maximum availability

Thanks to lithium-ion technology, long charging breaks are a thing of the past. CLARK FUSION batteries support fast charging and opportunity charging, allowing forklift trucks to be recharged during short work breaks without waiting for a full charging cycle.

Most models can be fully charged in approximately two hours, representing a significant advantage over conventional lead-acid batteries. These ultra-fast charging times enable electric forklift trucks to be used almost continuously. Operators no longer lose valuable working time to lengthy charging processes, and costly downtime is eliminated. Opportunity charging during breaks keeps the forklift fleet permanently ready for operation and significantly increases throughput.

Maintenance-free batteries: no effort, no downtime

Another major advantage of CLARK FUSION lithium-ion batteries is their maintenance-free operation. Unlike lead-acid batteries, there is no need for watering or regular refilling. The batteries are fully sealed and do not emit gases, eliminating the need for ventilation and making dedicated battery rooms or special charging areas unnecessary.

This reduces maintenance time and operating costs while minimising the risk of handling errors. Maintenance-free batteries also improve safety, as there are no acid splashes or hazardous fumes that could endanger personnel or equipment. Lithium-ion technology therefore enables clean, safe operation with minimal effort – a benefit that directly results in higher availability of your forklift trucks.

High energy efficiency and consistent performance

Lithium-ion batteries use supplied energy extremely efficiently. Up to 95 % of the energy drawn from the charger is actually stored in the battery, whereas lead-acid systems lose a significantly higher proportion as heat. This results in lower electricity costs per charge and shorter charging cycles.

At the same time, lithium-ion batteries deliver consistently high performance throughout the entire discharge cycle. A forklift truck equipped with a CLARK FUSION battery maintains full power almost until the battery is empty, without the typical performance drop associated with lead-acid batteries. Battery voltage remains stable, ensuring consistently high lifting and driving performance from the first to the last operating hour. In daily operations, this means no battery fatigue – full performance is always available. Overall, this leads to a more efficient forklift fleet.

Long service life

CLARK FUSION lithium-ion batteries are characterised by a significantly extended service life. Depending on the application profile, they offer at least twice as many charging cycles as lead-acid batteries – often considerably more. In practice, a single lithium-ion battery can replace several lead-acid batteries over its lifetime.

This durability reduces the need for frequent battery replacement and significantly lowers replacement investment. In addition, lithium-ion batteries can be opportunity-charged without negatively affecting their service life, making battery changes during or between shifts unnecessary. The days of keeping multiple spare batteries for multi-shift operations and performing labour-intensive battery changes are over. This not only reduces acquisition costs but also improves productivity and workplace safety, as heavy battery changes using lifting equipment are no longer required.

CLARK Fusion Battery Telematics

Each CLARK FUSION battery is equipped with an intelligent Battery Management System (BMS) that monitors key operating data. The system is fully integrated into the vehicle control system and communicates with both the forklift truck and the charger via CAN bus. Battery charge level and remaining runtime are conveniently displayed to the operator on the forklift truck’s display. At the same time, the BMS protects the battery against deep discharge and overcharging, contributing significantly to its long service life.

The CLARK FUSION battery is equipped with a smart 4G module. This enables real-time battery monitoring via the mobile network – even across different sites and national borders. Fleet managers can conveniently access battery status and performance data remotely. If irregularities or faults occur, the system sends automatic real-time alerts. Remote diagnostics allow issues to be resolved more quickly, minimising additional downtime. With this connected lithium-ion battery, CLARK opens a new chapter in Industry 4.0 for intralogistics. The combination of proven lithium-ion performance and state-of-the-art telematics ensures maximum transparency and control in forklift fleet management.

Conclusion: more performance, lower costs –
future-ready forklift fleets

CLARK FUSION lithium-ion technology takes your electric forklift trucks to the next level. Short charging times, maintenance-free operation, outstanding energy efficiency and long service life ensure maximum availability of your forklift trucks with minimal operating costs. At the same time, safety and sustainability are improved by moving away from lead-acid technology.

Fleet managers and logistics managers in particular benefit from the cost savings and reliability offered by lithium-ion forklift trucks. Secure the advantages of CLARK FUSION batteries today – the future of forklift energy is here.
