Results summary
Switching to a drop-in 72 V LFP starter battery reduces total starter system cost by $387,496 per locomotive over 10 years, pays back in 1 year, and materially improves reliability while eliminating routine battery maintenance.
Key takeaways
- LFP is a drop-in replacement with no controls integration required.
- Longer engine-off hold time with LFP reduces idle hours and fuel burn.
- Lower maintenance (no watering, less wear) and reduced no-start risk.
- Start reserve prevents stranding; near-zero no-start events at 100% effectiveness.
- Upfront battery cost is outweighed by lifecycle savings over the analysis period.
