How Long Do Electric Bike Batteries last?

An electric bike battery is a rechargeable battery that powers your electric bike. These batteries are designed to last a long time a large part of the cost of your electric bike. Batteries can be expensive, and you don’t want to have to spend your money on a new battery every few months. That’s why it’s important to know how long a battery will last before it needs to be replaced.

So in this article, we will explain exactly how batteries work, how to get the most life out of a battery, and how you can extend the lifespan of your electric bike battery.

How Long Do Electric Bike Batteries last?

If properly maintained, you may expect an electric bike battery to 3 three to 5 years. If you abuse it, your battery may last as little as a year. It all depends on how you ride and how you care for your electric bike.

Factors that determine the life span of the battery

Following are the factors on which the life span of electric bike’s batteries depends:

Type of the battery

The type of battery that you have determines the amount of time it will last.  If you have a lead-acid battery, it will last a lot longer than a lithium-ion battery.  Lithium-ion batteries(1) are more expensive, but they will last a lot longer.

Brand of the battery

The type of battery you have determines the life span.  Some companies make batteries that last longer than others.  If you have a high-quality battery, it will last longer than a low-quality battery.

Amount of times the battery has been charged

The more times you charge your battery, the less time it will last. Charging the battery more than once a month will extend the life of the battery. You should charge the battery as soon as it’s fully depleted. That way, you can get the most life out of your battery.

Battery’s age

Batteries get old over time. Older batteries are less likely to perform well and can become dangerous.

Value of current utilized

If you are constantly riding your electric bike at high speeds, you will use more power than if you are riding at a moderate speed.  This will drain your battery faster.

How can you extend the life span of your electric battery?

The longevity of your battery, like that of any other electrical item, is directly proportional to the amount of care you give it. External elements such as the temperature and humidity for example can shorten the life of your battery so avoid leaving your bike outside for extended periods.

Here are some of the suggestions for extending the life span of your electric bike batteries.

Use original charger

Use the charger that comes with your battery because it is particularly designed for charging it.

If your battery is overheating avoid charging it

In case your battery appears to be overheating, do not begin charging it. Instead, let it cool for a few minutes.

Recharge it when it’s halfway through its life

Do not let your battery discharge to 0%charge. Instead, recharge it when it’s approximately halfway through its life.

Remove the battery when going away from the electric bike

If you are going to be away from an electric bike for an extended period, make sure to remove the battery. Also, turn on the battery now and again to avoid severe self-discharge.

Unplug it at 100% to avoid overcharging

By disconnecting your electric battery bikes at 100%, you can avoid overcharging them. When you charge your battery overnight, make sure you unplug it first thing when you wake up.

Keep the battery in a cool, dry location

You can keep the battery in a dry location and this may be accomplished by parking your electric bike in a shady or out-of-the-way location.

Use a dry cloth to clean the electric bike

When cleaning the battery on your electric bike, use a dry cloth( nothing moist). Water might cause more battery corrosion, so don’t accidentally limit its life when servicing it.

Advantages of electric bike batteries

Electric bikes are becoming increasingly popular, and the electric bike’s battery is one of the most important components of an electric bike. Here are some of the advantages of electric bike batteries.

Designed to last longer than traditional bicycles

Electric bikes are powered by batteries.  Batteries are designed to last longer than traditional bicycles. This is because they are not powered by a combustion engine. So you will not have to worry about your electric bike battery becoming old or not lasting as long as you expect.
