Battery Refurbishment

Extending battery life through precision diagnostics and module-level reconditioning

See how MDK Sustech’s refurbishment protocols restore 80 %+ residual capacity, defer recycling costs and create profitable second-life applications.

Batteries should never retire early. At MDK Sustech, our battery refurbishment programme combines AI-driven health analytics, module-level reconditioning and factory-grade testing to breathe new life into EV, industrial and consumer packs.

The result: >80 % residual capacity backed by a 5-year performance warranty, slashing total cost of ownership up to 45 % while keeping critical metals in productive use for an extra 5–8 years.

AI-powered battery health mapping

State-of-Health Diagnostics

Identify viable cells in minutes using EIS spectroscopy, capacity fade modelling and predictive ML algorithms.

Our robotic test benches run electrochemical impedance spectroscopy (EIS), incremental capacity analysis (ICA) and self-learning ML models to grade every cell within 90 seconds. Data feeds a cloud-based dashboard that predicts remaining useful life (RUL), residual capacity and optimal second-life application—enabling buy-back pricing 30 % above market scrap value.

Precision repair without full teardown

Module-Level Reconditioning

Replace failing cells, upgrade BMS firmware and refresh thermal interfaces to restore OEM-grade performance.

Technicians open packs in ISO 14644-7 clean cells, swap degraded cells with matched-impedance replacements, flash new BMS firmware for balanced charging and install phase-change thermal pads. Each module undergoes dynamic cycling tests at 1 C/1 C for 50 cycles to validate capacity retention ≥80 % and internal resistance ≤110 % of spec.

From traction to stationary storage

Second-Life Integration

Repurpose EV modules into certified grid-storage systems, UPS units and micro-grid batteries.

Refurbished modules receive IP67 aluminum enclosures, active cooling and CAN-bus communication for seamless integration into BESS containers, telecom towers and commercial UPS racks. UL 1974 compliance and IEC 62619 safety certification open doors to global markets, delivering 2–3× residual value compared with raw material recovery alone.

5-year coverage you can bank on

Warranty & Performance Assurance

Industry-leading warranty backed by real-time monitoring and proactive maintenance alerts.

Every refurbished battery ships with a 5-year pro-rata warranty and IoT telemetry that streams temperature, voltage and cycle-count data to our NOC. Machine-learning anomaly detection triggers predictive maintenance alerts before faults occur, ensuring uptime >99 % and protecting ROI for operators and financiers.

Leasing, buy-back and revenue-share options

Circular Finance Models

De-risk refurbishment investment through data-backed financial structures.

Choose pay-per-cycle leasing, guaranteed buy-back or revenue-share models tailored to cash-flow needs. Our dashboard quantifies residual value, carbon credits and avoided mining costs, enabling CFOs to treat refurbished packs as circular assets on the balance sheet.
