KABOOM!!! That's the sound of an explosion, or perhaps of a 3,000-pound lead-acid battery hitting the floor—either way, it's something you definitely don't want to hear in your warehouse or DC. But that's a distinct possibility if your lift-truck battery changing room is improperly designed or managed.
Not only can a poorly run battery room pose a safety threat, but it can also be a drain on productivity and your budget. A badly designed operation can lead to congestion and delays, improperly rotated batteries, and costly fines for failure to comply with safety regulations.
We asked some lift-truck and industrial battery experts what advice they give their customers about battery room best practices. Here are some of their "dos and don'ts."
Where, and how big?
Although battery changing and charging rooms are often relegated to a back corner of the warehouse, that's probably not the optimal location. It's better to locate them closer to where vehicles are used so drivers don't waste time traveling from work areas to the battery room, says Drew Stump, service marketing manager for EnerSys, a global manufacturer of batteries that includes the Douglas, Hawker, EnerSys Ironclad, and General brands. In a very large DC, it may make sense to have a second battery room for, say, pallet jacks, if they are used on the opposite side of the building from vehicles like counterbalanced forklifts, he adds.
Make sure the location has adequate electrical service, keeping in mind that power distribution costs increase with the distance from the main power feed, say the experts at Battery Handling Systems Inc. (BHS) on the company's website. Plumbing—including drainage—will be needed for battery washing, filling, and safety equipment, they add. You'll also need a heating and cooling system to control the room's temperature; excessive heat or cold will shorten a battery's life.
How big should the room be? That will depend on how many vehicles and batteries you expect to service at one time, the type and size of the lift trucks, and whether the trucks will need to turn around inside the room, as well as the type and amount of battery handling and charging equipment you plan to use, says Jim Gaskell, director of customer support for lift-truck manufacturer Crown Equipment Corp.
When calculating floor space, try thinking in terms of "the slot"—an auto racing term for the space surrounding a vehicle, Gaskell suggests. "Once the truck gets there, what kind of space will it have? If you can't walk between trucks and still plug in the cable, then drivers will start banging trucks around to create their own slots," he says.
Leave enough space for both trucks and people to maneuver. Cramming battery changers and other equipment too close together creates a safety risk for pedestrians, says Tony Amato, vice president, sales and marketing for IBP, a distributor of batteries, battery handling equipment, and battery management systems. He's seen battery rooms where people were forced to walk in the same aisles used by incoming and outgoing vehicles, creating a safety hazard.
Larger fleets often use multilevel charging systems to save space. Some companies also find they can reduce the room's footprint by employing a combination of traditional and opportunity chargers, Amato says. An analysis of battery usage might show that you can accomplish the same work with fewer batteries, offering yet another opportunity to save space.
Remember to measure vertically, not just horizontally. Stump tells of one company that bought a four-level charger system only to find that it interfered with the battery room's ventilation system and was too close to the ceiling. "When planning a battery room, you have to measure twice and cut once. I can't stress that enough. That holds true for new construction as well as for existing facilities," he says.
The space outside the room is important, too. The path or aisle for approaching a battery room must be wide enough for trucks to pass each other when vehicles are lined up to enter, Gaskell says. It should also be clear of obstructions. This is a common problem in retail, where store inventory may block access to chargers. "I've seen operators leave the truck and not plug it in when they can't get in the charging area, so the next operator has a nearly empty battery or a partial charge," he says.
The inside story
Inside the battery room, one of the top concerns is traffic flow. "If several drivers come in at once, the first may be able to change in two minutes, but the tenth person waits 20 minutes," notes Terry Orf, administrative vice president of Materials Transportation Co. (MTC), a provider of battery changing equipment and the EBatt battery management software. He recommends a battery-discharge indicator and an interrupt that prevents the truck from operating when the battery is too low, to help spread visits to the changing room out over the course of the day.
Another approach is a system that schedules changes and electronically notifies operators of their "appointments." "You can schedule them almost like at an airport, queuing them up so the productivity of the warehouse is not adversely impacted," says Joe LaFergola, manager of business and information solutions for lift-truck maker Raymond Corp. Raymond offers that capability in its iWarehouse fleet management solution.
There are many ways to help drivers get in and out of the room in just a few minutes yet still connect to the right charger and choose the correct battery. Some are low tech, such as marking parking spaces on the floor or color-coding the battery connectors based on the type of truck—one color for reach trucks, another for stock pickers, and so forth. Hal Vanasse, vice president, sales and marketing for Philadelphia Scientific, a manufacturer of battery management systems and equipment, suggests organizing batteries and their associated chargers into "pools." For example, all pallet jack chargers and batteries would be grouped together.
Technology is playing a big role in matching the truck, charger, and battery in the most efficient, cost-effective way. Battery management systems on the market monitor charging, track each battery's status, optimize rotation, direct operators to the correct batteries and chargers, and alert managers when something is wrong, among other features. Just one of many possible examples: When drivers enter a room equipped with Philadelphia Scientific's iBOS battery management system, they select the proper "pool" on a touch screen and are directed to the rack location for the next available, fully charged and cooled battery for that type of truck. If the driver does not take the specified battery, a "shouter" alarm sounds over a loudspeaker, telling the driver (and everyone else within earshot) that he's taken the wrong one.
A battery may physically fit in a truck yet be undersized in terms of its charging capability, says LaFergola. Here again, technology can prevent such mistakes. If Raymond's iBattery system detects that the wrong battery has been installed, it will prevent the truck from lifting and will send an e-mail or text message to alert managers.
These and the many other high-tech tools available today have taken the guesswork out of battery management. But they shouldn't necessarily replace a manager who stays on top of battery conditions, enforces proper procedures, and keeps usage and maintenance records. Facilities that rely entirely on the truck operators "tend to have a few more problems," LaFergola says, because drivers are under time pressure and may not take the time to check water or keep maintenance records—omissions that can negate warranties when repairs are needed later on.
Play it safe
There are many opportunities for accidents—including fatal ones—to happen in a battery room, so safety must be top of mind throughout the planning stage. Although this complex subject merits an article of its own, we asked the experts for a few safety tips. What follows are their recommendations:
Place safety equipment like goggles, gloves, and aprons where operators can easily grab them before they get to the battery handling area. In addition, make sure the path to the eye-wash station is kept clear of obstructions.
Comply with specific ventilation requirements to prevent the buildup of explosive hydrogen gas emitted by batteries during charging. Also, keep the exhaust system separate from the general ventilation system so no air is recirculated, and consider installing an indicator light or alarm to alert operators if the exhaust system stops working.
Install code-approved concrete flooring that resists acid damage, use acid- or alkali-resistant and electrostatic paint where appropriate, keep batteries off the floor, and have acid neutralizers handy.
Consider safety when choosing battery changing and charging equipment. The more automated types cut down on opportunities for accidents, Orf says, from "man aboard" systems to something like his company's Intellichanger, where the operator only needs to disconnect the battery from the truck and stand behind a barrier while the equipment does the rest.
Consult applicable regulations and building codes issued by the Environmental Protection Agency (EPA), the Occupational Safety and Health Administration (OSHA), the National Fire Protection Association (NFPA), and others. Run your plans by your company's environmental health and safety department as well as local emergency responders, who may have jurisdiction over things like ventilation. "You don't want to build [a battery room] and find out later that the local fire marshal wants the floor coated or a containment system," Stump says.
Train operators and require strict adherence to proper procedures. Don't allow anybody on a machine who hasn't been trained to operate it. "A lot of people are OSHA-certified on lift trucks, but training on battery handling equipment is often neglected," Amato says.
An investment worth protecting
A financial commitment from the corporate level will help you get the resources needed for a properly designed, safely operated battery room, says MTC's Orf. It may not be easy to get management's attention, though. Corporate managers are often aware of the costs of purchasing and maintaining forklifts, but many times, they forget about the costs associated with battery changing and charging, he says.
Perhaps they should take notice. The value of battery-related assets alone merits attention: A facility with 100 forklift batteries has spent some $400,000 just for batteries, and it may have invested $100,000 in battery changing equipment and another $50,000 in chargers, Orf notes. "If you have multiple facilities across the country, then you're talking millions of dollars."

Supply chain planning (SCP) leaders working on transformation efforts are focused on two major high-impact technology trends, including composite AI and supply chain data governance, according to a study from Gartner, Inc.
"SCP leaders are in the process of developing transformation roadmaps that will prioritize delivering on advanced decision intelligence and automated decision making," Eva Dawkins, Director Analyst in Gartner’s Supply Chain practice, said in a release. "Composite AI, which is the combined application of different AI techniques to improve learning efficiency, will drive the optimization and automation of many planning activities at scale, while supply chain data governance is the foundational key for digital transformation.”
Their pursuit of those roadmaps is often complicated by frequent disruptions and the rapid pace of technological innovation. But Gartner says those leaders can accelerate the realized value of technology investments by facilitating a shift from IT-led to business-led digital leadership, with SCP leaders taking ownership of multidisciplinary teams to advance business operations, channels and products.
“A sound data governance strategy supports advanced technologies, such as composite AI, while also facilitating collaboration throughout the supply chain technology ecosystem,” said Dawkins. “Without attention to data governance, SCP leaders will likely struggle to achieve their expected ROI on key technology investments.”
The British logistics robot vendor Dexory this week said it has raised $80 million in venture funding to support an expansion of its artificial intelligence (AI) powered features, grow its global team, and accelerate the deployment of its autonomous robots.
A “significant focus” continues to be on expanding across the U.S. market, where Dexory is live with customers in seven states and last month opened a U.S. headquarters in Nashville. The Series B will also enhance development and production facilities at its UK headquarters, the firm said.
The “series B” funding round was led by DTCP, with participation from Latitude Ventures, Wave-X and Bootstrap Europe, along with existing investors Atomico, Lakestar, Capnamic, and several angels from the logistics industry. With the close of the round, Dexory has now raised $120 million over the past three years.
Dexory says its product, DexoryView, provides real-time visibility across warehouses of any size through its autonomous mobile robots and AI. The rolling bots use sensor and image data and continuous data collection to perform rapid warehouse scans and create digital twins of warehouse spaces, allowing for optimized performance and future scenario simulations.
Originally announced in September, the move will allow Deutsche Bahn to “fully focus on restructuring the rail infrastructure in Germany and providing climate-friendly passenger and freight transport operations in Germany and Europe,” Werner Gatzer, Chairman of the DB Supervisory Board, said in a release.
For its purchase price, DSV gains an organization with around 72,700 employees at over 1,850 locations. The new owner says it plans to investment around one billion euros in coming years to promote additional growth in German operations. Together, DSV and Schenker will have a combined workforce of approximately 147,000 employees in more than 90 countries, earning pro forma revenue of approximately $43.3 billion (based on 2023 numbers), DSV said.
After removing that unit, Deutsche Bahn retains its core business called the “Systemverbund Bahn,” which includes passenger transport activities in Germany, rail freight activities, operational service units, and railroad infrastructure companies. The DB Group, headquartered in Berlin, employs around 340,000 people.
“We have set clear goals to structurally modernize Deutsche Bahn in the areas of infrastructure, operations and profitability and focus on the core business. The proceeds from the sale will significantly reduce DB’s debt and thus make an important contribution to the financial stability of the DB Group. At the same time, DB Schenker will gain a strong strategic owner in DSV,” Deutsche Bahn CEO Richard Lutz said in a release.
Transportation industry veteran Anne Reinke will become president & CEO of trade group the Intermodal Association of North America (IANA) at the end of the year, stepping into the position from her previous post leading third party logistics (3PL) trade group the Transportation Intermediaries Association (TIA), both organizations said today.
Meanwhile, TIA today announced that insider Christopher Burroughs would fill Reinke’s shoes as president & CEO. Burroughs has been with TIA for 13 years, most recently as its vice president of Government Affairs for the past six years, during which time he oversaw all legislative and regulatory efforts before Congress and the federal agencies.
Before her four years leading TIA, Reinke spent two years as Deputy Assistant Secretary with the U.S. Department of Transportation and 16 years with CSX Corporation.
Serious inland flooding and widespread power outages are likely to sweep across Florida and other Southeast states in coming days with the arrival of Hurricane Helene, which is now predicted to make landfall Thursday evening along Florida’s northwest coast as a major hurricane, according to the National Oceanic and Atmospheric Administration (NOAA).
While the most catastrophic landfall impact is expected in the sparsely-population Big Bend area of Florida, it’s not only sea-front cities that are at risk. Since Helene is an “unusually large storm,” its flooding, rainfall, and high winds won’t be limited only to the Gulf Coast, but are expected to travel hundreds of miles inland, the weather service said. Heavy rainfall is expected to begin in the region even before the storm comes ashore, and the wet conditions will continue to move northward into the southern Appalachians region through Friday, dumping storm total rainfall amounts of up to 18 inches. Specifically, the major flood risk includes the urban areas around Tallahassee, metro Atlanta, and western North Carolina.
In addition to its human toll, the storm could exert serious business impacts, according to the supply chain mapping and monitoring firm Resilinc. Those will be largely triggered by significant flooding, which could halt oil operations, force mandatory evacuations, restrict ports, and disrupt air traffic.
While the storm’s track is currently forecast to miss the critical ports of Miami and New Orleans, it could still hurt operations throughout the Southeast agricultural belt, which produces products like soybeans, cotton, peanuts, corn, and tobacco, according to Everstream Analytics.
That widespread footprint could also hinder supply chain and logistics flows along stretches of interstate highways I-10 and I-75 and on regional rail lines operated by Norfolk Southern and CSX. And Hurricane Helene could also likely impact business operations by unleashing power outages, deep flooding, and wind damage in northern Florida portions of Georgia, Everstream Analytics said.
Before the storm had even touched Florida soil, recovery efforts were already being launched by humanitarian aid group the American Logistics Aid Network (ALAN). In a statement on Wednesday, the group said it is urging residents in the storm's path across the Southeast to heed evacuation notices and safety advisories, and reminding members of the logistics community that their post-storm help could be needed soon. The group will continue to update its Disaster Micro-Site with Hurricane Helene resources and with requests for donated logistics assistance, most of which will start arriving within 24 to 72 hours after the storm’s initial landfall, ALAN said.
