Kalmar has launched a next-generation lithium-ion (Li-ion) battery solution for its electric straddle carriers, strengthening its portfolio of sustainable cargo-handling technologies. The new Gen 2 battery is now available globally and delivers higher energy capacity, improved safety and longer operating times.
Developed to meet rising customer demand for efficient and environmentally responsible equipment, the Gen 2 battery features advanced cell chemistry that enhances thermal stability and extends battery lifespan. These improvements reduce replacement frequency and lower the total cost of ownership, while also supporting lifecycle sustainability goals.
With a nominal capacity of 533 kWh—an increase of 25 percent over the previous generation—and a usable capacity of 453 kWh, the Gen 2 battery significantly extends operating autonomy. Kalmar electric straddle carriers equipped with the new battery can achieve up to 10 hours of net operating time, depending on energy consumption.
The increased capacity enables more flexible charging strategies, including a combination of depot charging during breaks and hands-free opportunity charging during shifts. This flexibility supports hot-seat operations and uninterrupted productivity in demanding terminal environments.
To support the rollout of the new battery technology, Kalmar has also deployed a megawatt charging system (MCS) at its test facility in Tampere, Finland, reinforcing its commitment to next-generation electric solutions.
“Gen 2 represents a major step forward in terms of battery energy capacity, safety and operational lifespan,” said Marko Hopeaharju, Head of Horizontal Transportation Solutions at Kalmar. “With longer operating times and improved reliability, our customers can transition to fully electric fleets without compromising performance.”
Kalmar continues to position itself at the forefront of sustainable material handling, enabling ports and terminals worldwide to reduce emissions while maintaining high levels of operational efficiency.
