Ebikes are recently becoming more popular as a green and efficient mode of transportation. Unlike gas-powered vehicles, electric bikes don’t produce emissions that pollute the air.

But one question people often have about e-bikes is, “How long does the battery last?”

Generally, an electric bike battery will last between two and five years with proper care. This is the equivalent of between 1000-1500 charge cycles. The number of charge cycles an electric bike battery can go through before it needs to be replaced will depend on the quality of the battery.

How Do Electric Bike Batteries Work?

Electric bike batteries are made up of cells that store electricity. The number of cells in a battery will determine the voltage, and thus the power, of the battery.

The cells are connected in a series, which means that the voltage of the battery will equal the sum of the voltages of all the cells.

The capacity of an electric bike battery is measured in amp hours (Ah), and it determines how much charge the battery can hold. A higher Ah rating means that the battery can store more energy and will last longer before needing to be recharged.

Most electric bike batteries are made up of lithium-ion cells, as they offer the best balance of weight, power, and durability. Lithium-ion batteries are also used in laptops, cell phones, and other electronic devices.

How Long Does an Electric Bike Battery Last?

The lifespan of an electric bike battery will depend on several factors, including the quality of the battery, how it’s used, and how well it’s cared for. Generally speaking, an electric bike battery will last between two and five years, or between 1000 and 1500 charge cycles.

Of course, the actual lifespan of an electric bike battery will vary depending on the make and model of the battery, as well as how it’s used. For example, a regularly cycled battery (charged and discharged) will have a shorter lifespan than one that’s only used occasionally.

Likewise, a battery that’s constantly left at full charge will also have a shorter lifespan than one that’s regularly discharged and recharged. This is because lithium-ion batteries suffer from what’s known as “charge degradation.”

Charge degradation occurs when the cells in a battery are repeatedly charged to 100%, which causes them to degrade over time.

Different Models and How Long the Batteries Last

Here is a list of different electric bike models and how long, on average, their batteries will last:

Aventon Aventon level.2

This ebike uses the Aventon Level.two battery which is a 36v 11 ah battery. This will give you between 25 to 50 miles on a full charge, and it will take approximately four hours to charge the battery fully.

Factors That Affect How Long an E-Bike Battery Lasts

There are a few factors that can affect how long an electric bike battery lasts. These include:

The Quality of the Battery

E-bike batteries are available in a wide range of quality levels. The better the quality of the battery, the longer it will last.

E-bike batteries come in three main types:

Lead Batteries: Out of the three types given, they are the least desirable. They have the least life cycles, or, to be more specific, roughly 300 cycles. Try your best to avoid these if you’re looking for a lasting solution.

Nickel-Cadmium Batteries: These have a longer lifespan than lead batteries, with around 500 cycles. They’re not as popular as they once were because they’re quite harmful to the environment.

Lithium-Ion Batteries: These are the best type of battery you can get for your money. They have a lifespan of around 1000 cycles, which is almost double that of nickel-cadmium batteries.

How You Use the Battery

As I mentioned earlier, how you use your battery will affect how long it lasts. If you regularly cycle your battery (charge and discharge it), it will have a shorter lifespan than one that’s regularly discharged and recharged.

This is because lithium-ion batteries suffer from what’s known as “charge degradation.” Charge degradation occurs when the cells in a battery are repeatedly charged to 100%, which causes them to degrade over time.

So, if you want your e-bike battery to last as long as possible, it’s best to avoid charging it to 100% every time. Instead, charge it to around 80-85%.

The Environment You Use the Battery In

Another factor that can affect an e-bike battery’s lifespan is the environment you use it in. If you regularly ride your bike in hot weather, this will cause the battery to degrade faster than if you rode it in cooler weather.

This is because heat speeds up the chemical reactions inside the battery, which causes the battery to degrade faster. So, if you live in a hot climate, it’s best to store your e-bike battery in a cool, dry place when you’re not using it.

How Often You Use the Bike

The frequency with which you use your e-bike will also affect the battery’s lifespan. If you only use your bike once a week, the battery will last longer than if you used it every day.

This is because batteries degrade faster when they’re frequently used. So, if you want your e-bike battery to last as long as possible, it’s best to use it only when you need to.

How To Make Your Electric Bike Batteries Last Longer

Now that you know the main factors that affect an e-bike battery’s lifespan, let’s look at some tips to make your battery last longer. Here are a few things you can do:

Watch the Temperature

Avoid temperatures above and below zero. You could feel as though you have no control over it.

Throughout the year, as you are riding, the outdoor temperature will vary between being very hot and being very cold.

But that’s not the issue. Avoid keeping your battery out in the sun if you don’t have any immediate plans to leave. Additionally, avoid leaving them in warm vehicles or with backpacks exposed to the sun.

Cooler temperatures are ideal for battery storage. You should not leave your battery in extremely low temperatures, as doing so can shorten its lifespan, in the same way, extended exposure to heat might.

Keep It to a Minimum

When you are not riding, it is best to keep the battery at a minimum. This will help to increase its lifespan.

The majority of people tend to store their batteries fully charged.

While this does not sound harmful, it actually is. When the battery is fully charged for an extended period of time, it will start to degrade.

It is best to keep the battery at around fifty percent when you are not using it for long periods of time. If you are planning on storing your battery for an extended period of time, it is best to keep it at a lower percentage, such as twenty-five or thirty.

Clean the Battery

You should clean the battery regularly. This will help to increase its lifespan as well as improve performance.

Many people do not realize how important it is to keep the battery clean.

The build-up of dirt and dust can prevent the electrical current from flowing properly, resulting in a drop in performance. Additionally, if there is too much build-up, it can cause a short circuit.

To clean the battery, you can use a brush or a cloth. Make sure that you do not use any water or cleaning solutions, as this could damage the battery.

Keep it Dry

It is important to keep the battery dry at all times. If the battery gets wet, it could short circuit, which would cause irreparable damage.

If you are caught in the rain or if your bike falls into a puddle, make sure that you dry off the battery as soon as possible. You can use a cloth or a paper towel to dry it off.

Charge It Using the Original Charger

It is best to use the original charger that came with your battery. While aftermarket chargers might work, they can damage your battery in the long run.

Additionally, it is best not to leave your battery charging overnight. When you do this, you are putting unnecessary strain on the battery, which will shorten its lifespan.

It is best to charge your battery when you know you will use it soon. This way, you can avoid putting unnecessary strain on the battery.

Never Overcharge the Battery

Overcharging the battery is one of the worst things you can do. When you overcharge a battery, it will start to degrade. Additionally, it can cause fires or explosions.

To avoid overcharging the battery, ensure you never charge it for more than eight hours. Also, ensure you never charge it to more than one hundred percent.

Don’t Use It Right After Charging

This may seem counterproductive, but it is actually best to avoid using the battery right after you have charged it.

When you use the battery immediately after charging, you are putting unnecessary strain on it. Additionally, this can cause damage to the battery in the long run.

You should wait at least an hour after charging before using the battery. This will give the battery time to rest and will help to prolong its lifespan.
