Li-ion Batteries

Many e-scooters include lithium-ion batteries. These rechargeable batteries are low weight, have a high energy density, and are rechargeable. Having a high energy density means that the Li-ion batteries weigh much less as compared to how much energy they store. These batteries are so powerful that they are also used in the military and aerospace industries.

Li-ion batteries contain lithium-ion in the form of chemical compounds. Different types of lithium-ion compounds lead to differing safety, capacity, and output features in batteries.

All lithium-ion batteries come with charge cycles between 500 and 1000 depending on the manufacturer. They take less time to charge batteries and are in electric vehicles.

Lead-Acid Battery

Sealed lead-acid batteries are in electric scooters across the world. They are the oldest battery chemistry that is reliable and inexpensive.

Compared to lithium-ion batteries, these batteries have poor energy density and take longer to charge.

If you are a frequent user of your electric scooter then there is not much to worry about. You have to make sure that the terminals of these batteries are clean every time. If your electric scooter is sitting idle for a long time, then your battery may need maintenance to prevent damage.

Nickel-Metal Hydride Battery

Some electric vehicles also feature nickel-metal hydride batteries. These batteries have high energy density but they take a lot of time to charge (10 plus hours).

What is an Electric Scooter Batteries Life Span?

The battery lifespan is between 2 to 4 years.

The lifespan depends on several factors. These include the battery’s quality, how often you charge it, and whether you take care of it.

Electric scooter batteries last 4000 miles on average. For a regular user, this is not more than 3 years. But the good news is that these batteries are replaceable. So, your electric scooter can last longer.

When Should You Replace an Electric Scooter’s Battery?

The electric scooter’s battery has to be replaced in the following scenarios:

  • When the battery becomes damaged such as due to a short circuit.
  • When the battery fails to turn on.
  • When the battery stops charging.

Once you are aware that your battery is not working, you must replace it immediately. Not replacing the damaged battery may damage the electric scooter itself.

Replacing the battery

Electric scooters come in many forms and models. For example, there are scooters for kids and commuter scooters.

You have to make sure to buy the replacement battery from the same brand, model, and manufacturer as the original one. This will allow you to use the original charger made for your electric scooter’s model.

The price of battery replacement differs. For example, a lead-acid battery will cost much less than a lithium-ion or nickel-metal hydride battery.

How to Take Care of Your Electric Scooter’s Battery?

Here are a few maintenance steps to consider:

Don’t fully drain the battery

Electric scooter batteries are different from the ones in our cell phones. When using cell phones, most of us have the habit of draining the phone’s charge and then charging it full afterward. We should not charge the e-scooter battery in the same way as it can harm the battery.

You should maintain your electric scooter’s battery above 50 percent for your battery’s longevity.

Discharge the Battery Regularly

Discharging the battery completely after every 10-15 charges will give it a full charge cycle and enhance its performance.

Keep the battery at its optimal temperature

Using your electric scooter in extreme temperatures will take a toll on its battery. Charge your electric battery in a cool and ventilated area where there is an ideal temperature for the battery.

Cold temperatures reduce the battery capacity. If you live in a place where it is cold then make sure to charge your scooter indoors. Also, avoid storing the scooter where it is in contact with direct sunlight.

Let the Battery Cool Down

While it is best to charge your electric scooter as soon as possible after you have completed your journey. You should give your battery some time to cool down.

Features to Look For in an Electric Scooter Battery

When you are planning to buy an electric scooter keep in mind that the battery is the heart of it. That is why it is a good idea to check some of the features of the scooter’s battery pack.

Output Voltage:

In electric scooters, voltage affects the power of the motor. Higher voltage leads to high power reaching the motor. For best performance, the battery’s output voltage should be greater than the motor’s input voltage.

Electric scooter batteries are configured in

  • 24V
  • 36V and
  • 48V

Electric scooters with high voltages are faster. Some of the things that affect the scooter’s performance and charge can be:

  • Rider’s weight
  • Engine
  • Terrain

Battery Charge

Ah is the measure of the battery charge. Ah stands for Ampere-hour.

How many Ah is a scooter battery?

Electric scooters have a battery charge capacity of between 2 Ah to 50 Ah. The higher the battery charge the greater its performance.

Battery charge can be known by using this formula:

Storage capacity (Watt-hour) divided by Voltage (Volts)

E-scooter Battery Capacity

Often, electric scooter manufacturers do not show the battery storage capacity. Battery capacity is measured in Watt-hours.

Your electric scooter will cover a wider range if it has a high battery capacity.

The electric scooter battery capacities start from 100Wh-3000Wh

You can determine the battery capacity by multiplying the charge and the voltage.

1 Wh = 1 Ah x 1V

Here are some things you should know about your electric scooter battery:

Voltage Sag:

Electric scooters often experience a voltage sag. Voltage sag happens to all kinds of batteries in certain situations where the demand for power by the scooter becomes high such as:

  • The scooter is riding uphill.
  • The scooter is riding into the wind.
  • Short circuit
  • Electrical resistance

Voltage sag may also happen when you are traveling a long distance without charging the vehicle for a long time. The result is that the voltage drops. The solution to this issue is to switch off your scooter and let it rest for 5-10 minutes. This is so that it can regain the original voltage.


C-rate tells us how long it takes for the battery to charge. For example, if your electric scooter has a C-rate of 2C that means your scooter is charged in 2 hours.

Battery Brands

Your electric scooter battery’s brand determines its performance and quality. Some manufacturers produce some of the best e-scooters on the market.

Non-branded e-vehicles will also work fine on your regular commutes. The branded ones will deliver top-notch quality performance that you will enjoy.

Common Electric Scooter Battery Problems and their Solutions

Faulty Battery

Open the deck and inspect the battery. Check if there is any leakage. If you do not find any physical signs of a faulty battery then test the battery’s voltage. You can do this using a voltmeter. A low voltage means that you now have to replace your battery. The ideal voltage reading should be the same at the charging port and the battery pack.

There can also be issues with the electric scooter failing to charge. When charging the scooter, check whether it is showing the red light. The light should turn green when the battery is completely charged. If the lights are not showing as described above then that shows a faulty battery as well.

Old Battery

When you are charging the battery, the light is first red and turns green when charged. The green light indicates that more than 50 percent of your battery has been charged and it is being charged slowly to prevent overcharging.

If your charger’s light turns green sooner this is a sign that your scooter’s battery is getting old. It is time to replace this battery if your e-scooter is not able to reach its highest speed on a full charge.

An old battery may also show the followings sign indicating that it has to be replaced by a new one:

  • The battery fails to turn on.
  • It shows issues in charging such as it will continuously blink red light and not charge.
  • It will not charge at all or may take a long time to charge.
  • The scooter is not able to start.
  • Electric scooters may slow down. Old batteries fail to hold a charge for a long time. Hence even if you charge them fully, they will drain in no time.
  • Scooter’s motor gets overheated if the batteries are worn out.
