Here Are Some FAQ Most Riders Ask When Buying E-bike Batteries

Which battery is best for an Electric bike

There are few things to consider before deciding which battery might be a perfect option for you. How much range would the battery deliver, type of the battery, battery capacity, and its cost can be major factors to look into.

How many miles will I get from my battery?

This might be one of the most important factors when deciding on your e-bike battery.

How much mileage you can get on a single charge depends on different aspects, for instance how fast you ride, what kind of terrain you ride on, your weight, and the type of e-bike battery.

Most batteries provide information on how many miles a single recharge can travel. This is an estimate for ideal conditions and gives a rough idea of how long your battery charge would last.

Normally each mile uses 20 watt-hours. So a 480 watt-hour battery would give you around 24 miles. However, this can increase or decrease depending on the above-mentioned factors.

Electric bike battery types

What type of battery you select for your electric bike can be a tricky decision, considering there are several battery types with each of them having its pros and cons. I will mention some common to help you understand.

Lithium-ion might be the most common word you have heard when searching for the best e-bike battery. Basically, it is the battery that uses lithium in its composition.

Lithium Polymer is the most power-dense battery you can get. The power it delivers surpasses almost every other battery type and maybe a great choice for people who cycle on mountain tracks.

Lead-acid is another type of battery that is commonly used throughout the globe due to its high availability. Although they aren’t as power dense as Lithium Polymer due to their chemical composition.

Nickel Cadmium isn’t much suited for e-bikes because of the restriction of rapid discharge. The odd thing about this battery is that you have to fully charge before using it and discharge before storing it, which is completely strange when considering an e-bike application.

E-Bike Battery Capacity

What capacity E-bike battery do you need?

Calculating battery capacity gives you a rough idea of how many miles you can travel before needing to get a recharge. Although it might not be the only factor affecting the longevity of your bike, it is a smart choice to determine what capacity you will need.

This is where you might need to do a little maths. Watt-hours are used to determine how much is your battery capacity. Multiplying your battery voltage by the amp hours gives you Watt-hours.

For this, you need to consider your riding terrains. Cycling over hilly terrains drains your battery faster than cycling on a flat surface. The same is applicable for high speed at the highest PAS (Pedal Assist System) level.

For a normal person looking to cycle through neighborhood streets, a 480 Watt-hour should be an ideal choice unless you plan on riding uphill.

How much does it cost to replace an E-bike battery?

While electric bikes cut the cost of fuel, you need to replace e-bike batteries after a period due to the gradual decrease in capacity and efficiency.

And yes, e-bike batteries can cost anywhere between $300-$1000 depending on what they are to offer. A premium electric bike battery starts from $500 and can last more than 1000 recharge cycles. Interesting right?

Premium batteries offer 400+ watt-hour and deliver more range and power, exactly why they come with the additional cost. How much you need to spend to replace your battery depends on what kind and capacity you need. Typically though, expect to spend between $200 to $400.

How long does an E-bike battery last?

The lifespan of a battery is not calculated by the number of years, rather by the number of recharge cycles. To put it simply: How many times you have to charge your battery from 0-100% before the battery efficiency starts to decrease, and until it completely diminishes.

You can expect your battery to last from 2 years to 4 years, provided it is maintained well. There are few ways you can increase your battery life: keep it in a dry place and avoid temperature fluctuations, don’t fully discharge your battery too often, and store your battery partially charged.

Typically an e-bike battery can undergo hundreds of charge cycles, even the most powerful batteries have 1000 recharge cycles. However, the exact amount can depend on the battery type and the manufacturers too.

How to store your E-bike battery?

Storing an e-bike battery can be a delicate task since your battery lifespan depends on it. While many people find it difficult to get a perfect place for their e-bike battery, here are few points to keep in mind before considering your storage place.

You need a dry place to store your battery. Any moisture or contact with water can ruin, even dilute chemical composition in your battery resulting in a drastic decrease in performance and efficiency.

Lithium Polymer batteries are most sensitive to high temperature and combustible materials. Almost all experts and manufacturers agree that a battery should be stored between 10-20 degrees celsius.

People often make the mistake of storing the battery empty. It is always better to store your battery at 40-70% of its full capacity to avoid irreversible damages. On other hand, leaving your battery to charge for long periods of time in the storage area can also negatively affect your battery life.

How often should I charge my E-bike battery?

When and how often you charge your e-bike battery is directly related to your battery life and capacity.

There are two different ways people usually charge their e-bike batteries:

  • Charging after every ride to ensure that you are always prepared for your next cycling trip.
  • Charging at fixed battery intervals. Most experts recommend charging at 30% and 60% of its full capacity.

According to Battery University, partial charge and discharge are highly recommended since it reduces the stress on the battery. This prolongs the battery life and reduces the capacity drop as your battery ages.

Lithium batteries do not have memory therefore periodic full discharges and charges are not needed to prolong battery life. However, for other battery types, fully charging your battery every alternate week can ensure optimal working conditions.

Cycling between 25%-85% delivers a longer service life than fully charging to 100% and discharging to 50%. Keeping this in mind, you need to keep a track of your battery percentage before plugging in your charger.

What happens when an e-bike battery dies?

If your battery dies in the middle of your journey, you will no longer have pedal assist. To simply put: the battery will not supply any energy to the motor to assist your pedaling.

However, you can still continue to ride with your power like a regular bike. But remember, e-bikes are generally heavier than regular bikes that means you will need to pedal harder, especially on inclines and rocky dirt roads.

A good way to avoid this is to keep an eye on your battery charge on your e-bike display. In case you are using your charge way too fast, it is a smart decision to shift to a lower assist to help conserve your charge.

Tip: In case your battery dies, removing the battery will make your e-bike a little lighter and easier to pedal.
