The average lifespan of an e-bike battery is between 3-9 years, depending on its quality and how you use it. Once the battery has reached the end of its lifespan, it’s only normal for you to consider replacing it. Other warning signs to know you need to replace your bike battery include:
- Strange noises
- Reduced performance
- Overheating
Knowing the right time to replace your battery is one thing, understanding exactly how to choose the right one is another. With many battery products available in the market today, you certainly need to follow the best practices when buying a new e-bike battery. That said, below are a few factors worth considering during the buying process:
1. eBike battery shape
The shape of your current e-bike battery and the battery housing design certainly matter when replacing it with a new product. The shape can influence how the batteries are incorporated into the e-bike.
Before buying a replacement battery, you need to check the battery compartment. Depending on the compartment, make sure to choose an electric bike battery that comes with the same shape and dimensions as the original battery.
2. Battery range
The battery range of your e-bike means how far your electric cycle can travel on a single charge. Paying attention to the battery range certainly matters because it allows you to avoid full battery depletion—which can always reduce the battery lifespan.
To understand the ideal battery range for your bike, you need to factor in the following:
- How long distances are you looking to cover?
- Will you be riding off-road, such as on mountainous terrains?
- What riding mode will you be working with—eco or turbo mode?
Choosing the ideal e-bike battery range is crucial because it allows you to achieve the same bike efficiency and performance as the original battery.
3. Types of batteries
Batteries are available in different types today but not all of them are ideal for your electric bike. Some common battery options include:
- Lead
- Nickel-cadmium
- Lithium-ion
- Nickel metal hydride
To achieve the best results, we only recommend going for lithium-ion e-bike batteries. Nickel-cadmium, lead and nickel metal hydride batteries are not ideal because they’re limited in terms of lifespan, autonomy, and weight.
Lithium-ion electric bike batteries are known to be lightweight—they are at least 5 times lighter than lead batteries. This makes them ideal for achieving better riding performance. Besides, these batteries can always achieve higher energy density when compared to the other aforementioned battery types. Furthermore, a lithium-ion e-bike battery tends to offer greater autonomy and a better lifespan than lead and other battery types.
The bottom line is—lithium-ion batteries are better suited for electric bikes because they’re lightweight, last longer, and provide greater autonomy.
Furthermore, understand that lithium-ion batteries are available in different types today. Some common options are:
- Lithium NMC
- Lithium LFP
The right option depends on the current performance of your bike.
Experts at TT EBIKE can help choose the right battery type for your electric bike today. These experts will factor in your needs and help you choose a battery that fits your lifestyle.
- For higher energy density, all you need is a Lithium NMC battery. It will help you cover a longer range.
- The only problem, however, is that Lithium NMC batteries come with a shorter lifespan when compared to Lithium LFP batteries.
4. Battery power & voltage
Your eBike battery power and voltage are two things you certainly don’t want to joke with when choosing a replacement battery. The battery voltage matters, because it helps to determine your bike’s efficiency and motor speed. However, the battery power helps to identify your electric bike’s range. Choosing the wrong battery voltage can significantly damage your bike’s dual motor. This can also reduce your bike’s overall efficiency.
