This is a reliable, field-tested way to avoid massive expenses while restoring your vehicle’s range and health.

Most Common Chevrolet Bolt Battery Issues

Risk of Internal Shorts

Due to known manufacturing defects in certain year models, internal shorts can occur. Often, there are no early symptoms, making proactive diagnostics essential for your safety and the vehicle's longevity.

Cell Imbalance

Extreme temperature fluctuations can cause cell imbalance in the Bolt. This often leads to "Propulsion Power is Reduced" errors and a noticeable loss in vehicle dynamics.

Cooling System Failures

The Bolt uses a liquid-cooling system. Common failures include pump malfunctions, coolant leaks, or crystallization of the specialized Dex-Cool fluid, which can lead to overheating.

Degradation and Capacity Loss

After 150,000–200,000 miles, you may notice "range shrink" or erratic jumps in the State of Charge (SOC) percentage, indicating a failing module.

Wiring and Contact Oxidation

Depending on the humidity and road conditions in your area, the high-voltage wiring and contacts can oxidize, leading to isolation faults and charging errors.

Our Step-by-Step Chevrolet Bolt Battery Repair Process

Comprehensive System Scan

We begin with a deep-dive diagnostic of your Bolt’s high-voltage battery. We analyze every module’s status, monitoring temperature, voltage, and balance to identify the root cause of any error codes.

Weak Module Identification

The Bolt battery consists of hundreds of cells grouped into modules. Our specialized equipment identifies modules with high internal resistance, reduced capacity, or significant voltage drift.

Targeted or Full Replacement

We isolate and remove only the faulty sections or modules, replacing them with tested, high-health units to keep your repair costs manageable.

Precision Balancing

Using external balancing chargers, we equalize the voltage of the new modules to match the rest of the pack exactly. This ensures the Battery Management System (BMS) accepts the repair seamlessly.

Final Quality Test

Before delivery, we perform a rigorous validation: testing charge/discharge cycles, checking thermal management, and verifying all electronic control systems.

Transparent Digital Report

You will receive a detailed report including "before and after" photos, voltage/resistance data, a summary of the work performed, and expert maintenance tips.

What our client have to say

Frequently Asked Questions

What are the most common battery problems in a Chevrolet Bolt?

The main concerns involve manufacturing-related short circuit risks, cooling system leaks, contact oxidation, and cell imbalance.

Most Bolt batteries can be repaired by replacing specific modules. We recommend a full diagnostic first; usually, a targeted repair is sufficient to restore the vehicle.

Regularly monitor your cooling system, avoid frequent deep discharges (below 10%), keep the vehicle out of extreme heat when possible, and ensure the software is updated for optimal cell balancing.

Costs vary based on the number of modules needing replacement. However, by focusing only on the faulty components, we significantly reduce the total price compared to a dealership’s full-pack replacement.
