Custom and Discontinued Battery Systems
Specialty lithium battery packs for commercial, industrial, marine, hobby, drone-controller, and professional equipment, subject to inspection.
Start With a Free Photo Evaluation
Before paying for shipping, send us enough information to identify the device, battery system, charger, and visible condition.
- Photo of the complete device
- Close-up photo of the battery label
- Photo of the charger and charger-output label
- Manufacturer, model, and serial number
- Description of the symptoms and current runtime
- Any measured battery voltage
- Photos of impact, water, heat, or enclosure damage
How the Battery Revival Process Works
The process is designed to screen projects before shipping, document each approved return, and prevent unexpected work from beginning without authorization.
1
Submit Photos
Email clear photos, product identification, charger information, reported symptoms, and relevant damage history.
2
ULS Reviews the Project
We determine whether the product appears to contain a serviceable lithium battery and whether it may qualify for evaluation.
3
Receive Authorization
Approved customers receive a Service Authorization Number, shipping instructions, and the downloadable service packet.
4
Diagnosis and Quote
After arrival, the battery and device are inspected and tested. Paid work requires approval unless the selected service was prepaid.
5
Revival, Testing, and Return
Approved work is completed, the device is functionally tested, and the item is prepared for return shipping.
Project Eligibility
Acceptance depends on battery chemistry, construction, condition, replacement-cell availability, electronics, safety, and the ability to access and reassemble the product.
Projects That May Qualify
- Confirmed rechargeable lithium-ion battery systems
- Devices with weak runtime or rapid battery drain
- Devices that operate only while connected to power
- Battery packs that no longer charge correctly
- Discontinued or unavailable replacement batteries
- Accessible internal cells and serviceable enclosures
- Capacity upgrades that can be performed safely
Projects Not Accepted Automatically
- Products shipped without prior written approval
- Lead-acid, alkaline, or non-rechargeable batteries
- Loose, unlabeled, or unidentified lithium cells
- Swollen, leaking, punctured, burned, or smoking batteries
- Life-support, implanted, or critical medical devices
- Products with severe corrosion or water damage
- Devices that cannot be safely opened or reassembled
Program scope:
The ULS Battery Revival Center is for approved portable and specialty
lithium equipment. E-bike battery rebuilds are not processed through
this intake program.
Estimated Service Timeline
Timing varies based on the device, battery construction, parts availability, testing requirements, project complexity, and current workload.
Initial remote photo and project review
Physical diagnostic after the approved item arrives
Typical approved Battery Revival service
These timeframes are estimates and are not guaranteed completion dates. Priority service receives queue priority but remains subject to parts, testing, and project complexity.
ULS
ULS No-Fix Service Guarantee
If United Lithium Solutions performs an approved Battery Revival service and the serviced battery does not restore the intended battery-powered operation, ULS will refund the battery-service charge.
Shipping, approved diagnostic charges, chargers, control boards, device electronics, physical damage, water damage, proprietary software or firmware restrictions, and non-battery failures are excluded. The guarantee applies only to the battery service described on the approved estimate.
Featured Battery Revival Service
ForeFlight Sentry Battery Revival
Is your ForeFlight Sentry no longer holding a charge, shutting down unexpectedly, or operating only while plugged in? ULS evaluates the internal lithium battery and performs approved cell-replacement service when the project qualifies.
Important Battery Shipping Restriction
Do not ship a battery or device that is swollen, leaking, punctured, smoking, unusually hot, fire-damaged, recalled, or visibly unsafe. Contact ULS and provide photographs before taking the item to a carrier. The downloadable packet does not replace carrier packaging, documentation, acceptance, or hazardous-material requirements.
Battery Revival Questions
Can I ship my device immediately?
No. Submit photographs and product information first. ULS must issue written approval or a Service Authorization Number before the device is shipped.
Is the initial photo evaluation free?
Yes. The remote photo review is free. A paid diagnostic may apply after the approved item arrives and is physically inspected.
Does photo approval guarantee that the battery is repairable?
No. Photo approval means the project appears eligible for physical evaluation. Final serviceability can only be determined after the battery and device are inspected and tested.
Is the diagnostic fee credited toward the repair?
Yes. The diagnostic fee is credited toward an approved Battery Revival repair when the customer approves the service quote.
Can ULS increase my battery capacity?
Some products may qualify for a capacity upgrade. Approval depends on the enclosure, charger, protection electronics, cell configuration, thermal limits, operating requirements, and available replacement cells.
Who pays for shipping?
The customer is responsible for inbound and return shipping unless a product listing or written ULS estimate states otherwise.
What should I include in the box?
Include the completed first page of the Service Authorization Packet and only the device, battery, charger, power supply, or accessories requested by ULS. Attach Page 3 securely to the outside of the box.
Does ULS service e-bike batteries through this program?
No. The ULS Battery Revival Center page is intended for approved portable and specialty lithium devices rather than e-bike battery rebuilds.
