What Are the Types of E-Bike Batteries?

When purchasing an electric bicycle, the e-bike battery is one of the most important components. The battery determines how long the bicycle can be used without recharging, the distance it can travel, and how heavy and/or light it weighs.

It’s also one of the most expensive parts, so be sure to pay attention to the battery when you’re making an e-bike purchase.

Lead-acid Electric Bike Batteries

This was introduced in the 1800s. Lead-acid batteries are inexpensive and simple to recycle. They have a lower power output and are much heavier. Lead-acid batteries are the heaviest of the electric bike battery types available. They are three times the weight of lithium batteries and two times the weight of nickel batteries. Furthermore, lead-acid batteries have a lower capacity than nickel and lithium batteries. A lead-acid battery's maximum capacity is half that of a lithium or nickel battery. Though lead-acid battery design is among the earliest, it is not necessarily a problem. Over many decades, the technology has been proven and tested, and production methods have been developed to create high-quality, low-cost lead-acid batteries for hundreds of diverse specific applications.

Nickel-cadmium Batteries (NiCd)

Nickel-cadmium (NiCd) batteries have more capacity per pound than lead-acid batteries, and capacity is a vital factor to consider when purchasing an electric bike. However, nickel-cadmium is costly, and cadmium is a hazardous contaminant that is difficult to recycle.

NiCd batteries, on the other hand, will live longer than lead-acid batteries. However, because NiCd batteries are so difficult to recycle or dispose of properly, they are getting obsolete. They have a shockingly high rate of self-discharge. After a full charge and no use, they can drop by as much as 70% in as little as 24 hours. They have a poor density of electricity.

Nickel-metal Hydride Batteries (NiMh)

Although NiMH batteries are more efficient than NiCd batteries, they are also more expensive. The majority of people claim that NiMh has a minimal advantage over NiCd in terms of range. They will, on the other hand, last longer and are easier to dispose of properly. Despite this, nickel-metal hydride batteries are not long-lasting. They're difficult to keep in good working order, and charging them can be a difficult task. Even when used rarely, nickel-metal hydride batteries generate a lot of heat. Causing a high level of self-discharge.

Lithium-ion Battery (li-ion)

Newer or recent e-bikes will have some kind of lithium-ion battery as they are the most popular battery currently on the market.

Lithium-ion batteries optimize for both total weight and energy, giving you the best range and longevity to any other battery.

Li-ion battery types can also be molded into different shapes or unique spaces, making them ideal for high capacity and low power applications.


Lithium iron phosphate (LiFePO4) operates across a wide temperature range, making it a viable option for various applications or weather conditions. Its advantages include a longer life span, charge efficiency, no maintenance, extreme temperature operation and an ability to charge quickly.

As these batteries are relatively new in the market, they’re not the cheapest, but due to its long life span they are a smart investment over time.
