BATTERY SYSTEMS Repair Services India

Yes. Synchronics repairs the full Battery Systems product range including UPS modules, rectifier circuits, battery management systems, and inverter boards. We offer PAN-India door pickup and courier service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, and all major industrial cities. All repairs are performed at our fully equipped facility in Vadodara, Gujarat, with TAT of 5-10 working days for most Battery Systems electronics.

Synchronics performs comprehensive charger testing including regulated voltage output verification at no-load and full-load conditions, current limiting function test with adjustable load bank, ripple and noise measurement with oscilloscope, and thermal stability cycling from 5°C to 45°C. We verify float charge voltage accuracy within 0.5%, measure charging current in steps from 5A to rated capacity, and confirm soft-start ramp characteristics. Test reports document all parameters before shipment.

Battery Systems equipment communicates faults through LED indicators and, in newer models, digital displays showing cell voltage imbalance warnings, temperature sensor failures, charger overcurrent shutdown codes, inverter frequency deviation alerts, and battery capacity degradation messages. Synchronics maintains detailed fault code libraries for all Battery Systems product generations and performs root-cause analysis on each code. We trace faults to component level—whether voltage monitoring IC drift, thermistor failure, or control board microcontroller corruption.

Yes. Battery Systems inverters failing to produce AC output require systematic troubleshooting. Synchronics checks for gate drive signal presence at MOSFET gates using oscilloscope, verifies PWM control IC oscillation and frequency accuracy, tests transformer primary and secondary winding continuity, and measures DC output of bootstrap capacitor circuits. Most failures stem from failed gate drive optocouplers, PWM controller ICs, or power MOSFETs. We replace failed components, verify gating signals with load test, and commission the inverter before return.

Battery Management System (BMS) repairs at Synchronics typically require 7-10 working days depending on fault complexity. Simple cell monitoring sensor replacement takes 2-3 days. Complex faults like microcontroller firmware corruption or multi-point calibration errors require 8-10 days including component sourcing, reprogramming, and multi-point voltage verification. We expedite repairs for critical infrastructure customers and provide daily status updates. Urgent turnaround is available at premium cost.

Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.

Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.

All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.

Yes. If we cannot repair your BATTERY SYSTEMS unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
