Data centers generate lithium battery waste in lumps: a UPS refresh, a battery cabinet retirement, or a hardware decommission can put a large amount of material on your dock in a single week. A recurring recycling program lets facilities and EHS teams plan those events, document them for audits, and keep spent modules out of unmanaged storage rooms.
What battery streams do data centers generate?
The largest stream is uninterruptible power supply batteries. Many sites are moving from valve-regulated lead-acid strings to lithium-ion cabinets because of footprint and service life, which means older lead-acid strings and newer lithium modules often leave the building in the same project. Lithium-ion UPS modules are packed with rack-level battery management hardware, so they need to be identified by chemistry, voltage, and manufacturer before anyone can quote a pickup accurately or choose the right shipping containers.
Smaller streams add up over a year. Server and network gear carries lithium coin cells that hold system clocks and settings. Technician laptops, handheld scanners, and badge or access hardware add rechargeable cells. Some sites also operate on-site battery energy storage for demand management or backup, which is a separate and much larger end-of-life event that needs engineering input before removal and should never be handled as routine facilities waste.

- On-site energy storage racks, if installed
- Coin cells and lithium primary batteries from servers and network gear
- Laptop, tablet, and handheld device batteries
- Swollen or failed modules pulled during maintenance
How do universal waste rules apply to a data center?
Most spent lithium batteries from a data center can be managed under the federal universal waste rule in 40 CFR Part 273, which EPA confirmed in a May 2023 memo. Your status depends on how much universal waste you accumulate on site at any one time: a small quantity handler stays under 5,000 kg total, and a large quantity handler reaches 5,000 kg or more. A single lithium UPS cabinet retirement can push a site across that line, and once it does, the site keeps large quantity handler status for the rest of that calendar year.
Either way, you need labeled containers, trained employees, and a one-year limit on accumulation counted from the day a battery becomes waste. Large quantity handlers also notify the regulator and obtain an EPA identification number. Because rules differ by state and some states are stricter than the federal baseline, check the state page for your location before you write the site procedure, and have your EHS lead sign off on the storage plan.
What does a decommissioning or refresh project look like?
Plan battery removal as its own work package with a named owner, not as an afterthought to the hardware tear-out. Before the project, confirm chemistry, state of health, any visible damage, and whether modules can be de-energized and disconnected by your electrical contractor. Recyclers can usually quote more accurately when they have photos, nameplate data, and a count of modules per cabinet, so collect that information during the site walk rather than on removal day.
On removal day, expect to stage modules on pallets with terminals protected, damaged units segregated, and the shipment documented. Heavy modules may need a liftgate or forklift at the dock. If the batteries will ship by road, someone who signs shipping papers needs hazmat training under 49 CFR 172 Subpart H, or the recycler can take on that role as part of the pickup you arrange. Confirm who does what before the truck is scheduled.
How should a data center store batteries before pickup?
Store retired batteries in a dedicated, dry, cool area away from your white space, generators, and fuel, with a clear aisle and no stacked loose modules. Keep damaged, swollen, or recalled units apart from the rest in a non-combustible container, and make sure your fire suppression plan accounts for the room. Do not store spent lithium modules inside the data hall, where a thermal event would threaten critical load and complicate the response.
Mark each container with the words Universal Waste and a description such as Lithium-ion batteries, plus the date accumulation began. Tape or cap exposed terminals and keep a simple log of what went in and when. Inspect weekly for heat, swelling, or odor, and tell your recycler promptly if something changes, because damaged batteries ship under stricter packaging rules and may need a different container and carrier than healthy modules.
What records and sustainability data can a recycler provide?
Ask for a certificate of recycling or similar closure document for every shipment, along with the shipping paper or manifest and a count or weight by battery category. Keep these with your universal waste records for the period your state requires. Auditors and customers of colocation and cloud providers increasingly ask for end-of-life evidence on infrastructure, so a clean paper trail is part of the service you are buying, not an optional extra.
For sustainability reporting, weight diverted from landfill and metals recovered are the metrics most teams track. These figures can feed Scope 3 waste disclosures and corporate responsibility reports. Ask the recycler how the data is generated and what it covers, and do not publish recovery rates unless they come from a document you can show. Consistent reporting across sites also makes it easier to compare facilities and spot where batteries are being stored too long.

Frequently asked questions
Can we recycle lead-acid and lithium UPS batteries in the same pickup?
Often yes, but they are packed and documented differently, so tell the recycler about both when you request a quote. Lead-acid and lithium-ion modules should be palletized separately and labeled by type. Mixed loads can be quoted as one pickup in many cases.
Who is responsible if a module fails while we are storing it?
You are, as the generator, until the recycler takes custody. That is why damaged or swollen units should be isolated in non-combustible containers and reported right away. Your insurer and local fire code may also have storage requirements.
Do we need a data destruction certificate for batteries?
Batteries themselves rarely hold data, so data destruction is generally a separate service for drives and devices. If battery packs are integrated into laptops or storage hardware, handle the data question first, then the battery removal.
How often should a data center schedule battery pickups?
Many sites use scheduled pickups tied to maintenance windows plus on-call pickups for project events. The right rhythm depends on how fast you accumulate material and whether you are a small or large quantity handler.
