Where a third of your battery disappears

Standard industrial batteries can lose up to 35 percent of their capacity in a refrigerated warehouse. That single number explains a lot of what frustrates cold storage operators: the forklift that ran a full shift in the dry goods building suddenly needs a midday battery swap in the freezer, and nobody can quite say why throughput dropped.

Cold storage is one of the fastest-growing corners of the supply chain, pushed by online grocery and the broader cold chain. It's also one of the least forgiving. Equipment that performs fine at ambient temperature starts behaving differently the moment it crosses the dock into sub-zero air, and the operators running that equipment feel it too. The facilities that stay efficient are the ones that plan for the cold instead of fighting it.

What the cold does to equipment and people

Temperature is only the first problem. The bigger issues come from what temperature does over time.

Condensation is the quiet killer. Every time a truck moves from a freezer at -20°F to a warmer dock, moisture forms on metal and electronics. That cycle, repeated shift after shift, corrodes components and shorts out control systems that were never sealed for it. A pallet jack that lives in that swing of temperatures can rust from the inside out faster than most managers expect.

Control systems are vulnerable in a different way. Hydraulic fluid thickens, electronics behave unpredictably, and a truck not built for the cold throws faults that pull it out of service. Downtime in a freezer is expensive in a way ambient downtime isn't, because every minute a door stays open or a truck stalls is energy bleeding out of a space that costs a fortune to keep cold.

Then there's the operator. Working at -20°F is hard on people. Heavy gloves kill the dexterity needed for precise pallet placement, thick layers slow movement, and cold-related fatigue creeps into accuracy and safety. An operator who's uncomfortable is an operator who's slower and more prone to mistakes, and high-reach work in a freezer leaves little room for error.

Solutions built for the freezer, not adapted to it

The fix isn't a space heater bolted onto standard equipment. It's lift trucks engineered from the ground up for the conditions, with the right package matched to your specific temperature profile.

Cold storage conditioning is the foundation. Raymond protects sensitive control systems by matching hydraulic, mechanical, and electrical components to the temperature range they'll actually face. The packages are specced to the environment: a cooler running 50° to 33°F, a cooler/freezer swinging from 50° down to -20°F, or a freezer with an ambient dock. Getting that match right is what prevents the corrosion and control faults that sideline lesser equipment.

Power is where lithium-ion changes the equation. Raymond's IP65-rated lithium-ion battery is built with integrated heaters and thermal management, so the truck keeps performing as temperatures drop rather than fading partway through a shift. Longer run times and fewer battery changes per shift directly counter that 35 percent capacity loss, which means less downtime and more pallets moved per operator.

Operator comfort gets engineered in too. A heated control handle lets operators wear lighter gloves for better dexterity. A heated floor cushion keeps feet warm and cuts frost buildup in the compartment, and a thermostatically controlled heater shuts off automatically when the truck moves back into warmer air. The ThermaKit system provides steady warmth for operators spending full shifts in the freezer. Comfortable operators stay accurate and stay productive.

For the high-lift work that defines so many cold storage racks, the Vantage Point System mounts a high-resolution camera and color monitor on reach trucks, giving operators a clear view for placing pallets at height. It's rated for a -20°F to 110°F range, so it earns its keep in exactly the conditions where a missed placement costs the most.

Even the simple equipment matters. Galvanized hand pallet jacks like the LCF55 resist the corrosion that condensation causes, and corrosion packages extend that protection across the fleet.

Getting it right from the start

A few principles separate the operations that run smoothly from the ones constantly nursing equipment.

Spec to your real temperature zones, not your average. A facility with an ambient dock and a deep freezer is two environments, and the equipment should reflect that. Document the actual ranges each truck will cross before you buy.

Treat power as a system. Battery capacity, charging strategy, and run-time expectations all shift in the cold, so plan the fleet around how many trucks you genuinely need to cover a shift without surprise swaps.

Lean on proven performance rather than promises. Raymond maintains its own in-house cold storage test facility that replicates the harshest freeze and thaw cycles, which is why their trucks hold up in conditions that break equipment never built for them.

The takeaway

Cold storage punishes shortcuts. Equipment that wasn't designed for the environment costs you in corrosion, downtime, lost battery capacity, and worn-out operators, and those costs compound every shift. Purpose-built lift trucks, the right conditioning package, and a power strategy suited to the freezer turn that picture around.
