HV Battery Repair Experts

Expert Tesla high-voltage battery service designed to recover lost range, improve efficiency, and extend the usable life of your vehicle’s pack

Complete high-voltage battery restoration

We diagnose and repair complex Tesla high-voltage battery issues with OEM-level precision. Our certified technicians restore performance, range stability, and safety — without defaulting to full pack replacement.

Model S & X Modular Repair vs. Full Replacement

Tesla service centers typically recommend full battery replacement, even when only a few modules are affected.

 

EV Reviver specializes in Tesla Model S & X module-level battery repair, correcting cell imbalance and restoring pack health to OEM performance standards.

 

This approach allows many Model S & X owners in Orange County and Southern California to avoid costly full battery replacements while extending range and long-term reliability.

Model 3 and Model Y battery packs use a sealed, high-density cell architecture, making module-level repair impractical.

 

EV Reviver replaces the complete HV pack and performs BMS handshaking, coolant circuit bleed and balance, isolation verification, and inverter synchronization, restoring factory-spec performance and ensuring safe HV system operation.

 

Each replacement undergoes post-installation calibration and system validation to confirm stable power delivery, accurate range reporting, and long-term operational reliability.

Every high-voltage battery repair at EV Reviver is backed by a clear, reliable warranty, covering both parts and labor.

 

Choose from multiple coverage levels, whether you need module correction, BMS recalibration, or a full pack rebuild without being locked into a costly, restrictive terms.
