Battery Refurbishment Service | Lithium Battery Pack Repair & Rebuilding

Lion Battery provides professional Battery Refurbishment Services for lithium-ion, NMC, and LiFePO₄ battery packs. Battery refurbishment involves inspecting, testing, repairing, and rebuilding suitable battery packs to restore their performance and extend their usable service life.

Our refurbishment service is suitable for electric bikes, electric scooters, EVs, solar batteries, UPS systems, industrial equipment, robotics, telecom backup systems, and custom lithium battery packs.


What Is Battery Refurbishment?

Battery refurbishment is the process of evaluating an existing battery pack and replacing or repairing components that have degraded or failed.

Depending on the battery condition, refurbishment may include:

  • Battery Pack Inspection
  • Cell Voltage Testing
  • Capacity Testing
  • Internal Resistance Testing
  • Cell Replacement
  • Cell Matching
  • BMS Inspection
  • BMS Replacement
  • Wiring & Connector Replacement
  • Balance Lead Inspection
  • Battery Pack Reassembly
  • Charge & Discharge Testing

Battery Refurbishment Process

1. Battery Inspection

We inspect the battery enclosure, cells, wiring, connectors, BMS, and other components for visible damage or abnormal conditions.

2. Electrical Testing

Battery voltage and individual cell-group voltages are measured to identify imbalance or abnormal readings.

3. Cell Health Testing

Where appropriate, cells are evaluated using capacity and internal-resistance testing.

4. Fault Identification

Common problems such as weak cells, damaged wiring, faulty BMS units, connector issues, and excessive cell imbalance are identified.

5. Component Replacement

Depending on the findings, defective components may be replaced with compatible parts.

6. Cell Matching

Replacement cells or cell groups should have suitable electrical characteristics for the battery configuration.

7. BMS Inspection

The BMS and balance connections are checked for correct operation and compatibility.

8. Pack Reassembly

The battery pack is professionally reassembled with appropriate electrical connections and insulation.

9. Final Testing

The refurbished battery is tested for voltage, charging, discharge performance, and cell balance as applicable.

  • Custom Lithium Battery Packs

When Is Battery Refurbishment Suitable?

Refurbishment may be suitable when:

  • Battery capacity has decreased
  • One or more cell groups are weak
  • Cells are unbalanced
  • The BMS has failed but the cells remain suitable
  • Wiring or connectors are damaged
  • The battery enclosure is reusable
  • The battery has reduced runtime
  • The battery requires rebuilding

A complete replacement may be more appropriate when the cells are extensively degraded, the pack has severe physical damage, or refurbishment is not economically or technically practical.

Frequently Asked Questions

What is battery refurbishment?

Battery refurbishment involves inspecting an existing battery pack and repairing or replacing degraded components to restore suitable operation.

Can lithium batteries be refurbished?

Yes, some lithium battery packs can be refurbished, depending on their cell condition, BMS, enclosure, wiring, and overall safety.

Is battery refurbishment the same as battery repair?

They are related but not identical. Repair generally addresses a specific fault, while refurbishment can involve broader inspection, cell replacement, BMS work, rebuilding, and testing.

Can you refurbish an e-bike battery?

Yes. E-bike battery packs can be inspected for weak cells, imbalance, BMS problems, wiring faults, and reduced capacity before deciding whether refurbishment is suitable.

Will refurbishment make an old battery like new?

Not necessarily. Refurbishment can restore functionality and improve performance, but the resulting service life depends on the condition and quality of the remaining components.
