Lithium-Ion Batteries

The Battery Group is the UK's sole supplier of Triathlon® lithium ion batteries. Lithium ion battery packs are the ideal choice for industrial environments where workforce productivity is key. Reduce downtime with our range of lithium ion forklift batteries.

Why choose lithium-ion forklift batteries?

When it comes to running a modern warehouse, productivity is key. Lithium-ion batteries allow for multi-shift operations and more hours of actual lift truck usage. A never-ending drive to increase productivity in all sectors of manufacturing and logistics requires the full-time availability of electric forklift trucks. As more and more companies demand more power from their industrial lithium batteries, this has led to the rise of fast-charging lead-acid batteries.

How do lithium ion battery packs work?

Lead-Acid battery technology simply cannot achieve some of today's material handling demands without spare batteries and battery change-outs, especially in multi-shift 24/7 operations. After years of research, the team at Triathlon developed an innovative and cost-effective solution for heavy-duty electric motive power operations. Our lithium ion forklift batteries can be charged quickly, enabling multi-shift use without relying on expensive spare batteries and wasted time during battery change-outs. The systems are exclusively designed with high-performance lithium-ion cells which fulfil all requirements for heavy duty industrial motive power use.

How are lithium ion forklift batteries different?

Compared to conventional Lead-Acid batteries, lithium-ion technology has significant advantages. These heavy-duty batteries can be fully charged within 1-2 hours, even if the battery is fully discharged, to begin with. Unlike other batteries, opportunity charging will not damage the battery and is encouraged to streamline processes in your industrial environment. Time-consuming, unsafe and non-productive battery change-outs are no longer necessary. Lab results and real-life field testing of lithium-ion technology has found that these batteries deliver a significantly longer life than that of lead-acid batteries. Triathlon® lithium-ion battery packs are significantly more energy efficient than lead-acid batteries. The total efficiency of the system is up to 40% greater than that of lead-acid batteries.

Lithium-Ion Battery Systems

Made in Germany, the Triathlon® lithium-ion batteries are made up of lithium-ion cells that are assembled into modules which provide the required voltages and Ah capacities.  We offer complete lithium-ion battery systems in all standard battery voltages.  All cells are UN 38.3 tested.  Each battery system has an integrated monitoring system with a display unit and an opportunity charger.
