Forklift and industrial batteries are heavy motive power packs, and today they split between traditional lead-acid and a growing share of lithium-ion, mostly LFP. Lithium packs follow the lithium battery rules, while lead-acid follows its own recycling channel. This page explains how to tell them apart and how lithium forklift batteries are prepared, shipped and recycled.
How do you identify a lithium forklift battery?
Check the nameplate. Lead-acid forklift batteries are steel trays with removable cell caps and liquid electrolyte, and the label lists voltage, amp-hours and weight. Lithium forklift batteries are sealed, often similar in size so they fit the same truck compartment, and they carry a battery management system, a communication interface and a label stating Li-ion or LFP. They are usually lighter than lead-acid for the same energy, though still very heavy.
Voltages commonly match the truck, such as 24, 36, 48 or 80 volts, and capacities are rated in amp-hours or kilowatt-hours. Lithium packs in AGVs, scrubbers, aerial work platforms and pallet jacks are smaller. LFP is common in forklift service because of its stability and cycle life, though some packs use NMC. If you cannot confirm chemistry, send the manufacturer, model, serial number and photographs of the nameplate. If the same site has several battery generations, label each group so later staff do not have to relearn them.
- Nameplate: voltage, capacity, chemistry, weight, serial number
- Lithium cues: sealed case, BMS connector, no filler caps
- Lead-acid cues: removable caps, acid warning, steel tray
What hazards do industrial batteries present?
Weight is the first hazard: a motive battery is a crushing and lifting risk, and it must be moved with rated equipment. Lithium forklift packs add stored electrical energy, short-circuit current and thermal runaway risk if cells are damaged by a collision, crush, water intrusion or a charger fault. A pack that has been struck by a forklift fork or dropped from height should be treated as damaged.
Lead-acid batteries have different hazards: corrosive sulfuric acid, hydrogen gas during charging and lead. These are not lithium hazards, and separating the two chemistries in storage avoids mistakes. Charging areas should be ventilated and kept free of combustibles and open flames. Ensure staff know how to respond to fire in a warehouse, because lithium packs can reignite, and do not stack packs or lean them in aisles. Insurance carriers and local fire officials often have expectations for battery storage, so ask them before you build a staging area.
How should you prepare lithium forklift batteries for recycling?
Use a lift truck, hoist or battery handling equipment rated for the weight. Disconnect the battery connector, cap or insulate the exposed terminals, and place the pack on a pallet or in a cradle with straps so it cannot shift. Do not attempt to open the pack. Photograph the nameplate and any damage, and note the state of charge reading from the management system if it is available. Prepared batteries should wait in a cool, dry, supervised place, and the date they were prepared should be recorded.
Keep lithium and lead-acid separate and label them clearly. If a lithium pack has an alarm, a swollen case, evidence of impact or overheating, or has been exposed to water, treat it as damaged: move it outdoors or to a non-combustible area if you can do so safely, and tell us before shipping. If the manufacturer has a take-back or exchange program for the pack, ask about it, because core exchange arrangements may apply.
- Use rated lifting equipment and keep people clear
- Cap terminals and secure the pack on a pallet or cradle
- Segregate lithium from lead-acid and mark damaged packs
How are forklift batteries classified and shipped?
A lithium forklift battery shipped on its own is UN3480, and one shipped contained in or packed with equipment is UN3481, both Class 9 under 49 CFR 173.185. Because forklift packs weigh far more than 12 kilograms, large-battery provisions apply, which generally allow the pack to travel in a strong outer packaging or a fitted frame when terminals are protected and movement is prevented. Ground freight is the normal mode.
Damaged, defective or recalled lithium packs are governed by 49 CFR 173.185(f) and need packaging designed to contain a thermal event, along with correct marking, and sometimes special approval. Lead-acid batteries ship under separate rules. For example, wet batteries filled with acid are generally treated as corrosive material, not lithium. Tell us which you have, and we will confirm the right description, equipment and loading dock requirements before booking. Keep a copy of the shipping paper with the shipment record, since regulators and carriers may ask for it.
How do warehouses and manufacturers manage these as universal waste?
Spent lithium forklift batteries can be managed as universal waste under 40 CFR Part 273, consistent with EPA’s May 2023 memo that most lithium battery waste is hazardous waste that can use that pathway. Keep packs in a protected area, with closed and labeled containers where practical, and observe the one-year accumulation limit. Lead-acid batteries going to reclamation are covered by a separate set of federal provisions, so do not assume the same rules apply.
Warehouse operators, third-party logistics providers and manufacturers should make a hazardous waste determination, train employees on battery handling and keep records of shipments. Leased or fleet-managed batteries may be owned by a supplier who handles end-of-life, so check your agreement. State rules vary, and some states add requirements for battery storage or management, so check the state page for your location. The accumulation clock starts when a battery becomes waste or is received, so note the date on the container.
What is recovered from forklift batteries, and what affects cost?
Lithium forklift packs yield steel and aluminum from enclosures, copper from busbars and cell materials. LFP packs recover lithium, iron phosphate, copper and aluminum but no cobalt or nickel, while NMC packs also recover nickel, cobalt and graphite through black mass processing. Hydrometallurgy and pyrometallurgy are the main processes, with direct recycling still in research. Lead-acid batteries have a long-established recycling system that recovers lead and plastic.
Weight and chemistry dominate forklift battery pricing. LFP packs have lower metal value than NMC, so economics can be weaker per pack. Heavy packs require freight with a liftgate or forklift, and a damaged pack requires special packaging. Several packs moved together reduce per-pack transport cost.

Frequently asked questions
Do you take lead-acid forklift batteries?
Lead-acid has its own established recycling channel. Tell us what you have and we will help you route it appropriately, separate from lithium packs.
Can a lithium forklift battery be refurbished instead of recycled?
Sometimes, if the cells are healthy and the manufacturer or a specialist supports module replacement. If not, recycling is the end-of-life route.
Do I need special equipment to move the battery?
Yes. Use a rated lift truck, hoist or battery handling tool. Never move a pack by hand, and keep people clear while it is lifted.
What if a forklift battery was damaged in a collision?
Treat it as damaged. Isolate it outdoors or in a fire-rated area, do not charge it, and contact us for damaged battery packaging.
Is a core return program the same as recycling?
Not always. Core programs return batteries to the supplier, who may recycle or refurbish them. If you have a program, check its terms first.
