Bosch High-Voltage Battery Repair Kit (NiMH) for Toyota and Lexus

Restore Your Hybrid Car's Efficiency with Bosch Quality

Is your car's high-voltage (HV) battery faulty, less efficient than before, or have you noticed an abnormal increase in fuel consumption? There's no need to replace the entire, costly battery system. With the Bosch HV Battery Repair Kit, a global battery specialist, you can intelligently and ecologically re-energize your vehicle.

This repair solution allows you to replace only the outdated and faulty modules with new nickel-metal hydride (NiMH) accumulators. All other original components not subject to wear—such as the external metal structure (housing), the ventilation system, and the onboard electronics—are safely reused.

Advantages at a Glance

• Durable and Safe Repair: All NiMH modules within the battery pack are replaced, eliminating the residual risk of future failures caused by old, unreplaced cells.
• Cost-Effective and Eco-Friendly Solution: Only essential modules are changed, drastically reducing costs compared to purchasing a complete hybrid battery and minimizing environmental waste.
• Simplified Installation: The kit is designed for easy assembly by professionals. It does not require vehicle-specific special tools or complex software programming of battery modules.
• 5-Year Warranty: Bosch's high quality is certified by a long warranty period (from the kit's purchase date), for complete peace of mind while driving. The warranty covers manufacturing defects under normal use conditions (modified vehicles, driving schools, or taxis/commercial transport are excluded).

Vehicle Compatibility

The Bosch kit is custom-developed for the following vehicles equipped with NiMH technology:

• Toyota Prius III (2009-2015)
• Toyota Yaris (2012-2020)
• Lexus CT 200h (2010-2022)

Mini Replacement Guide for Workshops

1. Check the high-voltage battery's voltage while it is still installed in the vehicle.
2. Remove the battery, the module support plate, and other non-wearing components.
3. Replace the old modules with the new NiMH accumulators included in the kit.
4. Reinstall everything and recheck the high-voltage battery parameters.

⚠️ WARNING: Safety Requirements

The installation of this product involves critical high-voltage systems. Module replacement can and must be carried out exclusively by qualified personnel who have completed training on high-voltage systems (e.g., HV Level 3 qualification or PES/PAV according to local regulations). Bosch offers diagnostic support and specific courses ("High Voltage Expert HVE" and NiMH battery maintenance) to prepare your workshop for future mobility.
