Lithium UPS and backup batteries are rack-mounted modules and cabinets that provide ride-through power in data centers, telecom sites and critical facilities. They can hold substantial stranded energy and require trained de-energizing before removal. This page covers how to identify them, remove them safely and send them for recycling.
How do you identify lithium UPS and backup batteries?
Look for rack-mounted modules, cabinet-level battery systems, or UPS units with integrated lithium packs, each labeled with manufacturer, model, nominal voltage, capacity in kilowatt-hours or ampere-hours, and chemistry. Data center systems use LFP, NMC or in some cases lithium titanate (LTO) cells, while telecom sites often use 48-volt rack modules. Many facilities have both lithium and valve-regulated lead-acid (VRLA) batteries on site, so check the label before you assume. Mixed or unlabeled batteries should be photographed together and sorted by a trained person before packing.
Battery cabinets usually include a battery management system, a DC disconnect, communication ports and sometimes a monitoring display. Modules may be hot-swappable and rated by the manufacturer for replacement by trained service staff. The serial number and the manufacturer’s service record identify the module and its warranty status. For recycling, the weight, chemistry and any alarm or fault history are the most important details to pass along.
- Module label: voltage, kWh or Ah, chemistry, serial number
- Cabinet: DC disconnect, battery management system, communication ports
- Mixed sites: separate lithium from VRLA before requesting a quote
What hazards come with UPS and backup battery systems?
The hazards are stranded energy, DC arc flash and thermal runaway. Rack battery strings connected in series can reach voltages that cause severe injury, and a tool dropped across terminals can arc violently. Lithium modules that have experienced overcharge, overheating, coolant or water exposure, or a fault alarm may have damaged cells even if they look intact. Temperature extremes make every one of these risks worse, so avoid parked vehicles, direct sun and unheated sheds for storage.
Treat every module as live until the manufacturer’s lockout and isolation procedure has been completed and voltage is verified. Data centers and telecom sites often have fire detection and suppression designed for lithium batteries; do not defeat these systems during removal. Keep modules away from combustibles, do not stack them unsecured, and have an incident plan in case a module vents or smokes. A faulted module is a damaged battery, whatever it looks like.
How should you prepare UPS batteries for removal and recycling?
Use the manufacturer or a qualified electrician to isolate the battery string from the UPS, verify zero hazardous voltage and remove modules using the service procedure. Cap or insulate exposed connectors, and place modules on pallets or in racks with straps. Avoid shortcuts such as removing modules from live strings, because live removal is dangerous and can void warranties.
Record module serial numbers, chemistry and any fault codes. Keep faulted, swollen, hot or damaged modules separate in a non-combustible area and tell us they are damaged. If the module can be returned to the manufacturer under a take-back or warranty agreement, check that first. Note the dock configuration, lift equipment and access restrictions, since modules are heavy and secure sites often have scheduling rules that affect pickup. If you are unsure how to protect a particular terminal, ask us for guidance before taping or bagging it.
- Isolate, lock out and verify voltage before removal
- Cap terminals and keep modules secured on pallets
- Report faults, alarms or swelling before booking pickup
How are UPS and backup batteries classified and shipped?
Loose lithium-ion modules are UN3480 and modules contained in or packed with equipment such as a battery cabinet are UN3481, both Class 9 under 49 CFR 173.185. Most rack modules weigh more than 12 kilograms, so large-battery provisions apply, which generally allow strong outer packagings or fitted pallets when terminals are protected. Ground transport is the practical mode, as air shipment of these batteries is heavily restricted. Incorrect classification is the most common shipping mistake, which is why we verify the description before pickup.
Damaged, defective or recalled modules fall under 49 CFR 173.185(f) and require packaging that contains a thermal event, with correct marking. Faulted data center modules are common candidates for this category. VRLA batteries, which are not lithium, ship under different rules. Before pickup, we confirm chemistry, module count, total weight, condition and loading arrangements, and we advise on the right packaging for each group.
How do data centers and telecom operators handle these as universal waste?
Facility operators can manage spent lithium modules as universal waste under 40 CFR Part 273, consistent with EPA’s May 2023 memo on lithium battery waste. Keep modules in closed, labeled, protected containers and within the one-year accumulation limit. Facilities teams, colocation operators and integrators should make a hazardous waste determination, train the personnel who handle batteries and keep shipping and recycling records. A written plan and a labeled container are the simplest way to show the batteries are being managed correctly.
Colocation and managed-service environments can complicate ownership, so confirm who owns the waste and who signs. Many operators standardize on a staging area with fire protection and restricted access. State rules vary and may add requirements for storage or reporting, so check the state page for your site. Ask us about recurring pickups for refresh cycles, because large replacement projects benefit from planning.
What is recovered from UPS batteries, and what affects cost?
UPS batteries yield aluminum, copper, steel and cell materials. NMC modules produce cobalt, nickel, lithium and graphite through black mass refining, while LFP modules recover lithium, iron phosphate, copper and aluminum but contain no cobalt or nickel. LTO anodes contain titanium. Hydrometallurgy, pyrometallurgy and, in research, direct recycling are the main processes. Any claim about recovery rates depends on the specific recycler and process, so ask what the receiving facility actually does.
Module count and chemistry are the main cost levers for UPS work. LFP-heavy loads usually have less metal value than nickel-bearing chemistries. Large module counts allow full-truckload economics, and clean documentation reduces handling time. Faulted modules add cost for special packaging. We quote after you share module counts, weights, chemistry, condition and site access, and we can arrange pickup or prepaid shipping options. Ask for documentation of the final recycling steps if you need it for audits or internal records.

Frequently asked questions
Can facilities staff remove UPS battery modules themselves?
Only if they are trained and authorized under the manufacturer’s procedure. Many sites use the vendor or a qualified electrician. Live removal is dangerous.
Are lithium UPS batteries recycled differently from lead-acid UPS batteries?
Yes. Lead-acid batteries have their own recycling channels and transport rules. Tell us which you have, and sort them before pickup.
What if a module shows a fault code or is swollen?
Treat it as damaged. Isolate it, keep it dry and away from combustibles, and tell us before shipping so it can be packaged under the damaged battery rules.
Do you handle large refresh projects with many racks?
We can quote multi-rack projects and discuss scheduling, access and packaging. Provide module counts, weights and site details.
Is a certificate of recycling available?
Ask for documentation when requesting a quote. Documentation options depend on the recycler used for your shipment, and we will tell you what is available.
