Bentley Hybrid Battery Replacement

Full-Service Bentley Hybrid Battery Replacement

At MobileBattery, we specialize in Bentley hybrid battery replacement, offering on-site service for both the 12V auxiliary battery and the high-voltage hybrid battery system. Whether you drive a Bentayga Hybrid or a Flying Spur Hybrid, our certified mobile technicians deliver premium care to match the standards of your luxury vehicle—safely, discreetly, and professionally.

There’s no need for towing or dealership delays. We bring the tools, diagnostics, and expertise directly to your location.

 

Common Bentley Hybrid Models We Service

• Bentley Bentayga Hybrid

• Bentley Flying Spur Hybrid

• Future Bentley plug-in hybrid models

 

Bentley hybrids use a dual-battery system: a standard 12V battery that powers electronics and accessories, and a high-voltage lithium-ion battery that supports the electric drive. Over time, both batteries can degrade—resulting in electrical errors, reduced performance, or total power loss.

Bentley Hybrid Battery Replacement Process – Step by Step

Bentley vehicles are complex and require precision and care. Here’s what to expect when you book a Bentley hybrid battery replacement with MobileBattery:

 

Step 1: Book Your Mobile Appointment

Schedule online or by phone. Choose a time and location that’s convenient—home, office, or garage. We arrive fully equipped for the job.

​

Step 2: System Diagnostic & Evaluation

Using Bentley-compatible diagnostic tools, we perform a full system health check:

• Scan for hybrid drive error codes

• Measure high-voltage battery condition (state of charge & state of health)

• Test 12V auxiliary battery voltage and performance

• Verify cooling and energy recovery systems

 

We confirm battery condition and identify any secondary issues before replacement begins.

 

Step 3: Safe Removal of Old Batteries

Our technicians follow all Bentley factory protocols for safe high-voltage work. We:

• Isolate the vehicle’s high-voltage circuit

• Remove battery covers, ducts, and mounting assemblies

• Carefully extract both the 12V and high-voltage battery modules

• Prepare the old batteries for proper disposal and certified recycling

 

Step 4: Installation of New Batteries

We install OEM-spec or Bentley-approved batteries for maximum performance and longevity. This includes:

• Cleaning and preparing battery enclosures

• Installing both battery types to factory spec

• Reconnecting high-voltage and auxiliary systems with precision

• Reinstalling all protective panels and thermal management systems

 

Step 5: Coding, Programming & Battery Registration

Bentley hybrids often require post-installation configuration. We handle:

• 12V battery registration to recalibrate the intelligent charging system

• High-voltage battery initialization and ECU sync

• Clearing of historical codes and hybrid system memory

• Updating firmware, if required, using factory-grade tools

 

This ensures your Bentley operates at peak hybrid performance and avoids system faults.

 

Step 6: Final Testing & Post-Service Inspection

We complete a full post-installation test to verify:

• Proper hybrid power delivery and battery function

• Charging performance and idle stop/start functionality

• Error-free performance on all diagnostic systems

• Smooth electric drive transitions and regenerative braking

 

We only finish the job once your Bentley is performing like new.
