A Brief History of Electric Bike Battery Development and Innovation

Since the 1980s, ebikes have undergone significant transformations from combustion engines to the first Nickel Cadmium battery on the 1992 Zike ebike. Until 2001, many ebike manufacturers experimented with different energy cells to produce various battery types, giving ebike manufacturers affordable product options.

Cheaper ebikes got bulky lead acid batteries, while newer ebike models enjoyed lighter Lithium ion, Nickel Cadmium, and Nickel metal hydride batteries.

Here are the main types of ebike batteries explained, their advantages, and shortcomings.

Types of Ebike Batteries Explained

Scientists have developed different battery technologies and sizes suitable for electric bikes. Let’s compare and contrast the most popular electric battery types for your electric bike.

Lithium-ion (Li-ion) Electric Bike Batteries Explained

Lithium-ion batteries are the most popular type of electric bike batteries because they require less regular maintenance than the other types.

While they all work more or less the same way, lithium-ion ebike batteries come in different types - lithium manganese batteries, lithium-ion polymer batteries, NCA, NCM, and LiFePO4.


  • High capacity to power your electric bike for long distances when fully charged.
  • Low self-discharge and rarely lose power on standby.
  • No memory effect; hence they don't need to be charged regularly to maintain capacity.


  • Slightly more expensive compared to the other battery types. 
  • They are easily damaged when exposed to low temperatures.

Lead Acid Ebike Batteries Explained

A Lead acid battery is a rechargeable ebike battery that uses lead and sulphuric acid, whose chemical reaction produces electricity.


  • Most affordable electric bike battery
  • High current density provides much more power
  • Work perfectly under all weather


  • Heavier than Li-ion batteries, ultimately slowing down your electric bike.
  • Prone to discharging on standby, making them less efficient for non-daily commuters who must charge them again before use.

Nickel-Cadmium (NiCd) Ebike Batteries Explained

This electric bike battery uses nickel oxide hydroxide and metallic cadmium as electrodes. However, they are not as common as Li-ion and Lead acid batteries.


  • Fast to full charge 
  • Low cost and very affordable
  • Have high power density


  • High self-discharge on standby
  • Have a memory effect

Nickel Metal Hydride (NiMH) Ebike Batteries Explained

Nickel-metal-hydride batteries have been in use for many years thanks to their high density compared to lead-acid batteries. 


  • Easily replaceable
  • Have a high capacity
  • Less toxic to the environment.


  • Slow charging rate 
  • Low energy density

Key Features To Look For

Different electric bike batteries share universal features you should note before you go ebike shopping for your preferred supplier. 

Voltage of Ebike Batteries Explained

Voltage is the amount of electrical pressure or force your ebike battery produces; higher voltage means more energy to power your ride. 

Note that battery voltage depends on the size of the ebike, meaning ebike batteries for smaller ebikes have less voltage and vice versa.  

Ideal electrical bike batteries are between 36V-48V.

Capacity of Electric Bike Batteries Explained

Battery capacity is the energy the battery cell generates, usually expressed in Amperes (amps). 

The battery’s amps/hour rating (ah) lets you understand how much amperes your battery provides every hour. 

The best ebike batteries have a high capacity, usually 10 ah.

Watts of Electric Bike Batteries Explained

Watts denotes the combined power unit when your ebike battery’s Volts and Amps act on each other.

You will find that most ebike batteries have between 300-500W, but more ebikes are embracing the powerful 700W batteries.

You can tell the amount of Watts your battery produces every hour with the Watts/hour rate (Wh)

Battery Brands and Manufacturers

If you want to get the most power out of your electric bike battery, a good warranty, and peace of mind, shop for trusted brands.

The most popular ebike battery brands use power cells from independent manufacturers, such as:

  • Samsung 
  • Panasonic
  • Yamaha
  • LG 
  • Bosch

These manufacturers provide cells for the most sought-after battery brands, which have been tried and tested by many reviews and electric battery guides with the best ebike batteries explained.

5 Factors to Consider Before Buying an Electric Bike Battery 

Before buying an ebike battery from any brand or store, consider the following factors to get the best quality products.


Buy a battery from a reputable brand/manufacturer to get high-quality products with efficient features and a valid warranty in case Murphy’s law applies.


The weight of your ebike battery has a significant effect on the general performance and handling of your ebike.

Most ebike batteries weigh 4-8 lbs, depending on their size, chemical components, and energy capacity. The high-capacity batteries weigh more than lesser-capacity batteries.


If properly taken care of, an excellent electric battery can serve you for at least three years without showing signs of weakness or faulty discharge.
A durable battery saves you from regular maintenance expenses and buying a new battery every year.


Quality isn’t cheap, so don’t expect any less when getting a good ebike battery. Not all expensive batteries guarantee quality, so always weigh the cost vs. performance.


The best type of ebike battery is readily available on the market. A unique battery is all fun and games until you begin the hassle of getting spare parts or replacing them if it is a rare brand.

FAQs About Electric Bike Batteries Explained

Here are some other common concerns by ebike battery researchers, plus additional information to check out. 

What Is the Lifespan of Ebike Batteries?

A good Lithium-ion ebike battery has a lifespan of around 3-5 years, depending on the brand and how well you take care of it. Check out everything you need to know about Lithium-ion batteries and their care.

Do All Ebikes Have Removable Batteries?

Not all ebikes have removable batteries. Some ebikes have integrated batteries inside the bike’s frame, also known as hidden batteries, while others can be detached.

The placement of your battery entirely depends on your ebike model.
