# How Many Ah is a Tesla Battery?

by Phil Borges // in Car

Tesla’s electric cars are powered by lithium-ion batteries, which are known for their high energy density, long cycle life, and low self-discharge rate. The capacity of a Tesla battery is measured in kilowatt-hours (kWh), which is a unit of energy. However, the amp-hour (Ah) rating of a battery is also an important metric to consider, as it represents the amount of current that can be drawn from the battery over a specific period of time.

## How Many Amp Hours is in a Tesla Battery?

The amp-hour rating of a Tesla battery depends on the specific model and the size of the battery pack. The current lineup of Tesla cars includes the Model S, Model X, Model 3, and Model Y, each with different battery options. The standard battery pack for the Model S and Model X is 75 kWh, while the Model 3 comes with a standard battery pack of 50 kWh or an extended-range pack of 75 kWh. The Model Y also has a standard battery pack of 75 kWh.

To calculate the amp-hour rating of a Tesla battery, you can divide the battery capacity in watt-hours by the battery voltage. For example, the standard battery pack of the Model 3 has a capacity of 50 kWh or 50,000 watt-hours. The battery voltage of a Tesla is around 400 volts. Therefore, the amp-hour rating of the Model 3 battery pack is:

50,000 Wh / 400 V = 125 Ah

## How Many Amp Hours is a Tesla Model 3 Battery?

As mentioned above, the standard battery pack of the Tesla Model 3 has a capacity of 50 kWh or 50,000 watt-hours. The battery voltage of a Tesla is around 400 volts. Therefore, the amp-hour rating of the Model 3 battery pack is:

50,000 Wh / 400 V = 125 Ah

## How Many Amp Hours Does a Tesla S Have?

The standard battery pack for the Tesla Model S has a capacity of 75 kWh or 75,000 watt-hours. The battery voltage of a Tesla is around 400 volts. Therefore, the amp-hour rating of the Model S battery pack is:

75,000 Wh / 400 V = 187.5 Ah

## How Many Amp Hours is a Tesla Powerwall 2?

The Tesla Powerwall 2 is a home battery storage system that is designed to store energy generated by solar panels or from the grid during off-peak hours. The Powerwall 2 has a capacity of 13.5 kWh or 13,500 watt-hours. The battery voltage of the Powerwall 2 is 350-450 volts. Therefore, the amp-hour rating of the Powerwall 2 is:

13,500 Wh / 400 V = 33.75 Ah

In conclusion, the amp-hour rating of a Tesla battery depends on the specific model and the size of the battery pack. The higher the battery capacity, the higher the amp-hour rating will be. Understanding the amp-hour rating of a Tesla battery is important for determining how long the battery can provide power and how much power it can deliver at any given time.
