Do you live in West Sacramento, own a Chevrolet Volt, and need a professional battery diagnostic? We are here to help! For over 10 years, Maxat Hybrid Repair has specialized in the expert repair of hybrid batteries.
Battery issues in hybrid vehicles don’t always require a full replacement. To help you avoid unnecessary expenses, we perform deep diagnostics and repair only the faulty modules.
If your vehicle is 8–10 years or older, you may notice rapid charge depletion, the engine switching to gas mode earlier than usual, or a drop in the capacity of specific modules.
Have you noticed incorrect temperature sensor readings? Over time, the Chevrolet Volt can develop coolant leaks, pump failures, or clogged heat exchangers.
If a module is degrading or overheating, charging may be interrupted or take significantly longer. Often, the issue lies within the battery itself rather than the charger.
As the vehicle ages, the likelihood of contact oxidation, corrosion, or wiring failures between modules increases.
If the voltage across modules varies significantly, the State of Charge (SOC) fluctuates, or the car limits power output, your battery is likely out of balance.

We begin with a comprehensive diagnostic of your Chevrolet Volt's battery. We check the condition of every module, monitoring temperature, voltage, and balance to pinpoint the exact cause of the error.

Using specialized equipment, we identify modules with high internal resistance, reduced capacity, or voltage imbalances—a common issue for the Volt.

We replace the failed battery modules with high-quality OEM-grade components, restoring your hybrid’s full performance. This cost-effective solution extends battery life without the expense of a full replacement.

We replace only the faulty modules to save you money. In cases of total failure, we perform a complete battery pack replacement.

After replacing modules, we perform deep restoration and balancing. This equalizes the voltage across all sections, optimizes charge distribution, and minimizes variance between modules.

Before returning your vehicle, we conduct rigorous testing: verifying charge/discharge cycles, monitoring temperature control, and diagnosing the cooling and electronic systems.

All faulty modules are replaced with genuine Chevrolet components. This ensures your vehicle remains reliable and extends the overall lifespan of the battery.

We provide an industry-leading 4-year warranty covering manufacturing defects, giving you total peace (Warranty terms may vary—please contact us for specific details.)

Battery repair can be expensive, which is why we offer selective replacement—fixing only what is broken without the need for a full, costly overhaul.

The most frequent issues include individual module degradation, cooling system malfunctions, charging interruptions, oxidized contacts, and module imbalance.
It depends on the specific failure. We recommend a full diagnostic to find the source of the problem. In most cases, the battery can be repaired successfully without a total replacement.
Regularly check the cooling system, avoid extreme overheating or deep discharges, use moderate charging habits, and ensure your modules remain balanced.
The cost depends on the extent of the damage. To keep your costs down, we focus specifically on repairing or replacing only the malfunctioning modules.
