How to choose a right battery for e-scooter

The popularity of electric scooters is rising, driven by their convenience, user-friendly nature, and eco-friendly appeal. It is crucial to choose the best battery for e scooter to ensure the best performance and safe riding experience. When choosing the optimal battery, several key factors should be considered: type, battery capacity, size & weight, battery cycle life, and durability. Analyzing these specifications will reveal which battery can supply dependable power while satisfying personal requirements. Furthermore, one must comprehend how batteries interconnect with accompanying components like motor controllers and speed regulators to ensure all parts function in unison. This guide offers comprehensive insights into choosing the right battery for  e-scooter.

Types of Battery for E-scooter

The initial step in this selection process involves identifying the type of electric scooter you own. Different models may necessitate specific battery types, such as lithium-ion (Li-ion), lead acid, or NiMH. Moreover, distinctions arise in power sources, with some scooters featuring integrated rechargeable batteries, while others rely on external battery units. Precisely adhering to the manufacturer’s specifications is crucial in this regard.

Battery types

Sealed Lead-Acid (SLA) Battery:

Chemistry: SLA batteries use lead and sulfuric acid as their primary components.

Construction: Typically, they are built using lead dioxide for the positive plate, sponge lead for the negative plate, and a sulfuric acid solution as the electrolyte.

Lithium-ion (Li-ion) Battery:

Chemistry: Lithium-ion batteries employ lithium ions as the primary charge carriers, shuttling between the anode and cathode throughout the charging and discharging processes.

Construction: The typical construction includes a lithium cobalt oxide (LiCoO2) or other lithium-based compound as the positive electrode, a graphite anode, and a lithium electrolyte.

Nickel Metal Hydride (NiMH) Battery:

Chemistry: NiMH batteries use a combination of nickel oxide hydroxide and metal hydride as their positive and negative electrodes, respectively.

Construction: The positive electrode is typically made of nickel oxyhydroxide, the negative electrode consists of a hydrogen-absorbing alloy, and the electrolyte is an alkaline solution.

Comparison of These 3 Types of Battery

Battery Types



Sealed Lead-Acid (SLA) Battery

Cost-Effective: SLA batteries are relatively cheaper than other types, making them an economical choice.
Robust and Reliable: They can withstand a range of environmental conditions and provide a steady output, making them suitable for basic electric scooter applications.
Weight: SLA batteries are heavier, which will also affect the overall weight of the electric scooter.
Limited Energy Density: SLA batteries typically exhibit a lower energy density in comparison to lithium-ion batteries, leading to a reduced range per charge.

Lithium-ion (Li-ion) Battery

High Energy Density: Li-ion batteries offer a high energy-to-weight ratio, providing a longer range for electric scooters.
Lightweight: Li-ion batteries are lighter than SLA batteries, contributing to better overall scooter performance and handling.
Long Cycle Life: They generally have a longer cycle life than SLA batteries, meaning they have more charge and discharge cycles.
Cost: Li-ion batteries can be more expensive upfront, although the cost has been decreasing over time.

Nickel Metal Hydride (NiMH) Battery

Balanced Performance: NiMH batteries offer a good compromise between the cost-effectiveness of SLA batteries and the higher energy density of Li-ion batteries.
Environmental Impact: NiMH batteries are less toxic than some other types, making them a more environmentally friendly option.
Lower Energy Density: While higher than SLA batteries, NiMH batteries typically have a lower energy density compared to Li-ion, resulting in a somewhat shorter range.

Battery Capacity

Capacity rating is another pivotal factor when determining the appropriate battery for your electric scooter. This rating signifies the amount of energy the battery can store before requiring a recharge. Generally, higher capacity ratings translate to longer rides per charge, albeit at a higher initial cost. Additionally, external factors such as terrain and weather conditions may also affect the life of a scooter battery. By carefully weighing these factors, users can pinpoint the most fitting battery option.

Battery Size and Weight

When choosing a battery for a scooter, size and weight are critical factors. Larger batteries enable expanded range and power, but heavier units impact maneuverability and transport. It is vital to balance performance and portability.

Battery capacity, which is measured in Ah or Wh, directly relates to size. More capacity means more stored energy and range per charge, but scooters have load limits. An oversized battery may exceed stability thresholds.

What do Ah and Wh means?

  • Amp-hours (Ah) measure the amount of electric charge stored in a battery. It refers to how many amps a battery can provide over one hour. For example, a 15Ah battery can offer 15 amps for one hour before being depleted. Or it can deliver 5 amps for two hours, and so on. The higher the amp-hour rating, the more total electric charge the battery contains.
  • Watt-hours (Wh) measure total electrical energy storage capacity. It is calculated by multiplying a battery’s voltage by its amp-hour rating. For example, a 36-volt battery rated at 10 amp-hours has 360 watt-hours (36 x 10 = 360Wh). This means it can deliver 360 watts of power for one hour. Or 180 watts for two hours, etc. Watt-hours give an energy capacity that allows comparison between batteries of different voltages. Generally, higher watt-hour batteries have greater range/runtime for a given application.

Additionally, weight affects convenience. Heavier batteries reduce nimbleness and prove challenging to carry via public transit or on foot due to added mass. Existing infrastructure like staircases and doorways may further complicate transport if total vehicle weight surpasses thresholds.

Battery Cycle Life and Long-term Durability

Battery cycle life and long-term durability are crucial factors to consider when choosing a battery for your e-scooter because they directly impact the overall lifespan and performance of the vehicle. Opting for a battery with a higher cycle life ensures a longer-lasting and more cost-effective solution, as frequent replacements can be both inconvenient and expensive. Long-term durability is essential to withstand the various conditions and stresses an e-scooter may encounter during its operational life, ensuring reliable and consistent performance over an extended period. Considering these factors is essential for maximizing the efficiency and sustainability of the electric scooter while minimizing the need for premature battery replacements.


For users prioritizing cost-effectiveness and basic performance, SLA batteries may be a suitable choice. Users seeking a compromise between performance and cost may choose NiMH batteries.  However, users seeking high performance, longer range, and lighter weight may prefer the advantages offered by Li-ion batteries. The choice of battery for e-scooter depends on individual preferences, budget constraints, and the specific requirements of the electric scooter user, such as desired range, weight, and overall performance.

To optimize both performance and safety, it is imperative for individuals to thoroughly assess their specific requirements before selecting a battery model for their electric scooter.
