What happens to the battery after an electric car has been idle for a long time?

Modern electric cars are equipped with high-tech lithium-ion batteries that require a special approach to operation. Contrary to some myths, "leaving and forgetting" an electric car for months without consequences for the battery will not work. Let's figure out what happens to the battery in such a situation and how to properly prepare it. You can also improve your car and make it more comfortable using tuning accessories, a huge selection of which is available in our online store.

What happens to the battery in idle mode?

The main process that affects a battery when idle is natural self-discharge . Even without use, a battery gradually loses its charge. If the charge falls below a critical level (usually around 0-5%), this can lead to irreversible damage to the cells.

Ideal conditions for long-term storage

To preserve the life of your expensive battery, follow these rules:

• Charge level: It is optimal to store an electric vehicle with a battery charge of 50-70%. This is a golden mean that minimizes self-discharge and stress on the cells. Avoid storing at 0% or 100% charge.
• Temperature: Place the car in a cool, dry place (15–25°C) without sudden temperature changes. Avoid direct sunlight and severe frost.
• Plug in: If possible, leave your electric vehicle plugged into a charging station. Many modern electric vehicles have a float mode. If not, check the battery once a month and charge to 50-70%.

Return to service

After a long period of inactivity, if the battery is not completely discharged, simply plug the car in to charge. It is advisable not to apply maximum loads at first and not to use fast charging.

Properly preparing your electric vehicle for extended periods of inactivity is key to maintaining the health of its most expensive part, the battery. Don't ignore these simple rules and your electric vehicle will last you a long time.
