Battery manufacturers are developing swappable lithium battery packs that replace lead-acid batteries in legacy electric vehicles like golf carts and forklifts without requiring modifications. This shift offers faster charging, longer life, and cost savings, targeting vast markets where existing lead-acid machines remain in service.
- 01Trojan Battery Company's OnePack lithium battery is designed to integrate seamlessly with legacy electric vehicles, maintaining compatibility with existing systems.
- 02The global forklift market was valued at approximately $82 billion in 2024, indicating a significant opportunity for lithium battery retrofits.
- 03Lithium batteries can charge in 1-2 hours, compared to 6-8 hours for lead-acid batteries, allowing for efficient operation across multiple shifts.
- 04Trojan's OnePack can deliver up to 4,000 charge cycles, replacing multiple lead-acid batteries over its lifespan, which can lead to a return on investment within 36 months for high-utilization operations.
- 05The industry is facing challenges with compatibility as new battery technologies evolve, requiring ongoing validation to ensure performance across different equipment models.

A significant shift in industrial electrification is occurring with the introduction of swappable lithium battery packs that replace traditional lead-acid batteries in electric vehicles such as golf carts and forklifts. Companies like Trojan Battery, Dakota Lithium, and Relion Battery are leading this innovation by engineering lithium packs that fit into existing systems without requiring modifications to the vehicles. This approach is appealing due to the faster charging times, longer lifespan, and reduced operational costs associated with lithium batteries. The global forklift market alone, valued at around $82 billion in 2024, represents a large opportunity for these retrofits. Trojan's OnePack lithium battery, for example, is designed to work within the voltage tolerances of legacy systems, providing a straightforward solution that avoids the need for new equipment purchases or extensive modifications. However, as battery technologies evolve, ensuring compatibility across different models and generations remains a challenge that manufacturers must address to maintain market viability.
