An electric vehicle's battery is its most important component. It determines how far you can drive, how responsive the vehicle feels during acceleration, and ultimately how much value your vehicle retains if you decide to sell it in the future.
The good news is that modern EV batteries are far more durable than many people expect. With the right usage habits, they can remain in excellent condition for years. On top of that, VinFast offers battery protection programs designed to provide peace of mind regardless of your everyday driving habits.
Let's take a closer look at both.
Understanding Battery Degradation: Normal, But Manageable
Battery degradation is a natural process that affects all batteries, including those used in electric vehicles. Over time and through repeated charging cycles, battery capacity gradually decreases, which means maximum driving range may slowly decline.
The important thing to understand is that this process happens gradually, not suddenly. With proper care, battery degradation can be significantly slowed down.
There are three main factors that accelerate battery degradation:
Excessive Heat
High temperatures are one of the biggest enemies of lithium batteries. Leaving a vehicle under direct sunlight for long periods or frequently using DC fast charging when the battery is already hot can accelerate battery wear.
Charging at Extreme Battery Levels
Regularly draining the battery to very low levels (below 10%) or charging it to 100% for daily use places unnecessary stress on the battery.
Excessive Use of DC Fast Charging
Fast charging delivers higher electrical current, generating more heat within the battery cells. Occasional use is perfectly fine, but relying on DC fast charging as your primary charging method over the long term is not ideal for battery health.
Tips for Maintaining Your VinFast Battery
Keep Daily Charge Levels Within the Ideal Range
For everyday driving, most EV manufacturers and battery experts recommend maintaining battery levels between 20% and 80%.
This range helps minimize unnecessary stress on the battery.
Charging to 100% is best reserved for situations where you genuinely need maximum range, such as long-distance travel. For everyday commuting, it is generally unnecessary.
Make Home Charging Your Primary Habit
As discussed in our charging guide, charging at home using a Portable Charger or VinFast Home Charger is the most battery-friendly solution for long-term use.
AC charging generates less heat than DC fast charging, and its slower charging process is gentler on battery cells.
Use DC fast charging when necessary, such as:
- During long-distance travel
- When time is limited
- As a backup charging solution
It should not replace regular home charging whenever possible.
Avoid Leaving the Vehicle at a Very Low State of Charge
If the vehicle will not be used for several days, ensure the battery remains at a reasonable level.
Around 50% charge is generally considered suitable for short-term storage.
Leaving the battery nearly empty for extended periods can negatively affect cell health.
Take Advantage of Pre-Conditioning Before Long Trips
When planning a long journey, especially on hot days, use the VinFast app's pre-conditioning feature to adjust cabin temperature before entering the vehicle.
This not only improves comfort but also reduces the workload on the air-conditioning system when your journey begins, indirectly reducing energy demand on the battery.
Keep Vehicle Software Updated
VinFast vehicles receive over-the-air (OTA) software updates.
These updates often include battery management optimizations that can improve efficiency and, in some cases, extend battery longevity.
Make sure your vehicle is running the latest software version whenever available.
VinFast Battery Warranty: Two Approaches, One Goal
In addition to proper battery care, VinFast offers battery protection programs designed to address one of the most common concerns among prospective EV buyers:
"If something happens to the battery, how much will it cost to replace?"
The answer depends on the battery ownership model you choose.
VinFast offers two fundamentally different options.
Option 1: Battery Included
Under this model, you purchase both the vehicle and the battery as a single package.
There is no recurring monthly battery fee.
Battery protection follows VinFast's standard warranty terms of:
Up to 10 years or 200,000 km, whichever comes first
This is an exceptionally competitive warranty period. By comparison, many EV manufacturers offer battery warranties ranging from five to eight years with specific mileage limits.
Option 2: Battery Subscription
Under this model, you purchase the vehicle while the battery remains under VinFast ownership through a monthly subscription plan.
Subscription fees vary depending on the vehicle model.
In return, customers receive:
Lifetime battery warranty coverage for as long as the subscription remains active.
As long as subscription payments continue, VinFast covers battery-related issues without a time limit.
However, there is another feature that makes this model particularly attractive.
The Warranty Follows the Subscription, Not the First Owner
If you sell your VinFast vehicle in the future, the next owner can simply continue the battery subscription and receive the same protection as if they had purchased the vehicle new.
There is no reduction in warranty benefits and no shortening of coverage periods.
Drive Worry-Free: The VinFast Ownership Experience
Battery protection is part of a broader ownership program known as VinFast Drive Worry-Free.The initiative is designed to address many of the concerns people commonly have before and after purchasing an electric vehicle.
Beyond battery protection, Drive Worry-Free includes benefits such as:
- Complimentary charging at V-Green charging stations for a specified period
- Residual value guarantee programs
- Ownership solutions designed to provide greater confidence over the long term
Taken together, these programs reflect VinFast's approach to EV ownership: not simply selling vehicles, but supporting customers throughout their ownership journey.
FAQ
Can EV Battery Degradation Be Prevented Completely?
No. Battery degradation is a natural electrochemical process and cannot be eliminated entirely.
However, proper charging and usage habits can significantly slow the process and help maintain performance for many years.
What Does the VinFast Battery Warranty Cover?
Generally, the VinFast battery warranty covers manufacturing defects and capacity loss beyond specified thresholds under normal operating conditions.
For detailed coverage information specific to your preferred model, please contact your nearest VinFast Sales Advisor.
Does the Battery Warranty Remain Valid After the Vehicle Is Sold?
For Battery Subscription vehicles, yes. Coverage continues as long as the subscription remains active and is transferred to the new owner.
For Battery Included vehicles, warranty coverage follows VinFast's applicable warranty terms. Please consult VinFast for transferability details.
Which Is Better: Battery Included or Battery Subscription?
The answer depends on your priorities.
Battery Included may suit buyers who prefer complete ownership without recurring monthly payments.
Battery Subscription may appeal to those seeking maximum peace of mind and potentially stronger long-term resale value.
A VinFast Sales Advisor can help determine which option best matches your driving habits and ownership needs.
