The one-third of ebikes cost is the cost of the battery. The battery is the most important part of an ebike. As the electric bike has its power coming from the battery. It is very important to buy an electric bike with a battery life cycle of 3 to 5 years. The battery type used in the most electric bike nowadays is lithium batteries.

How long will the ebikes battery last

The ebikes batteries are made of lithium-ion or lithium polymer technologies. Lithium batteries are not new to our world these batteries have been originally created in 1912.

They have been in the market since then. This technology was very underrate at first but in the last 20 years, it has covered a lot of places in the market replacing other battery types.

The lifespan of an electric bike battery can vary depending on the quality, usage, and handling of the battery. Most estimates set the range at two to five years or 10,000 to 30,000 miles. Modern lithium-ion batteries are typically rated for somewhere from 500 to 1000 cycles. One cycle is a full charge from empty to 100% or twice from 50% to 100%, and so on. However, when your battery reaches its rated number of cycles, it should still have around 70% of its original capacity.

For example, Bosch states that its batteries, rated for 500 cycles, “should have 60 to 70% of the original capacity” after reaching that number. Achieving the manufacturer’s charge cycle rating with the battery in good condition assumes that you follow the charging, use, and storage guidelines. For example, avoid allowing your battery to drain completely or overcharge, keep it in a cool, dry area, and store it long term with around 30 to 60% charge.

The battery will last according to the charging life cycle of the battery. The lithium ion batteries have charge cycles upto 1000 times. This is a great number of cycles as by this your ebike can last easily upto 2 to 5 years depending upon your use.


While You’re going to buy an ebike or just batteries for an e-bike; It is very important to have in your mind that you should buy the batteries from trusted sources and trusted manufacturers.

The three best battery manufacturers are 

  1. Samsung
  2. Panasonic
  3. LG 

Here are some factors that we should consider while buying the battery.

Each battery type has its own lifespan

Each battery type has its own life cycle. They will be of no use after they reach their limit of cycles, One should have to replace the battery once its charging life cycles come to an end.

The type of battery has theoretical life cycles as the build of the battery plays a very vital role. As the poorly build lithium battery will be less efficient than the good quality built nickel battery.

  • Lithium battery has a lifespan of  1000 charge cycles.
  • Nickel battery has a lifespan of 500 charge cycles.
  • The lead battery has a lifespan of 300 charge cycles.

You should have a clear knowledge of batteries. There is a law that the battery should have 2 years of warranty. Take great care of the batteries’ health. If you notice a fast discharge of the battery percentage after some months then it is for sure a manufacturing defect and you should reclaim it.

What if a battery reaches its maximum number of charge cycles?

The manufacturer has given the theoretical results that a battery can undergo the given life cycles in average conditions. While in reality, it is depending upon how the battery discharges its life. The battery that has been given great care can perform up to the life cycles. If your battery has been discharging fast and is no use of yours you can replace it. Or if the battery is still going to fulfill your needs you can use it for more life cycles.

When an electric battery reaches its maximum number of charge cycles, its performance is expected to diminish. The number of cycles an electric battery will have can range anywhere from 500 to 1200, depending on both the type and chemistry of the battery. Once the cycle count is reached, a replacement battery is recommended to maintain performance. 

Signs of Battery Deterioration

The battery is made of chemicals that generate power-storing capabilities. If the battery will not use for a long time the battery will start discharging it self this phenomenon is known as Self Discharging. The self-discharging occurs because of the chemicals inside the battery.

Sometimes these chemical reactions end up giving irreparable damage to the battery. The battery should be preserved properly according to the guideline manuals. Each company has its own set of instructions according to the type of batteries.
