Cold-storage forklifts face a harsher environment than the spec sheet numbers suggest. Condensation, seal failure and battery performance drop-off are the real differentiators between trucks.
Battery chemistry
Lithium-ion batteries hold capacity far better than lead-acid in sub-zero conditions, and opportunity-charge between shifts without a dedicated battery room.
Sealed components
Look for a cold-store package with sealed electrical connectors and moisture-resistant hydraulics — condensation on cycling between zones is what kills unsealed trucks early.
