This article aims to provide you with a useful guide. Therefore, we will discuss tips for safe charging and storing of lithium-ion batteries, as well as measures to take in case of emergencies.
How to Safely Charge an Electric Bicycle Battery
Most reported battery fires occur during the battery charging process. Therefore, consumers must be extra cautious when charging. Here are some tips regarding the correct charging process:
Always use the charger recommended by the manufacturer; if you purchase an aftermarket charger, ensure that it has UL certification and specifications identical to the original charger. Using a fast charger for non-fast-chargeable batteries can be dangerous.
Avoid placing the battery near heat sources such as heaters. High temperatures can damage lithium-ion batteries and lead to thermal runaway incidents.
Do not place the charger or battery on or near flammable materials like wooden furniture or building structures. Always try to place the charger and battery on a fire-resistant surface or space.
Always keep the battery within sight while charging. As an additional precaution, place a smoke alarm near the battery.
In the event of a fire, the initial few seconds are crucial as you still have a chance to extinguish it before it becomes uncontrollable; therefore, prompt response is essential.
Turn off the battery while charging.
It is normal for the charger to become warm during the charging process, but the battery should never become hot (warm to the touch). If you notice the battery becoming hot, disconnect it.
Avoid charging in temperatures below zero degrees as this can cause dendrite growth on lithium-ion batteries, leading to short circuits and fire incidents.
Charge in a well-ventilated area.
Do not leave the battery charging overnight.
Proper Storage of Lithium-Ion Batteries
The lithium-ion battery of your electric bicycle requires proper storage, and you can take some measures to ensure appropriate storage.
When storing the battery for an extended period, charge it to around 60%.
Avoid storing it in extreme temperatures or high humidity.
Do not use damaged batteries that are dropped, punctured, squeezed, or otherwise compromised.
If a lithium-ion battery catches fire, use a fire extinguisher to put it out (be cautious as such fires produce toxic smoke).
Avoid extinguishing lithium-ion battery fires with water, although it can be used to extinguish the fire, a report by the U.S. Department of Energy found that it requires excessive amounts of water.
Do not store batteries or charge them near a single point of exit.
Safe Use of Lithium-Ion Batteries
If the battery starts smoking, making unusual noises, or shows signs of melting, stop using it immediately and place the battery in a safe location.
If you notice drastic changes in voltage/performance, discontinue using the battery.
If you immerse the battery pack/bicycle in water, have it professionally inspected before using it again (moisture inside the battery pack indicates water has entered and may cause a short circuit).
Always use the battery with the product it comes with; do not use it for any other purposes.
Emergency Response Measures
For any electric bicycle owner, following the tips mentioned earlier can reduce the likelihood of emergencies. However, accidents can still happen. Therefore, it is important to familiarize yourself with measures to ensure the safety of yourself, loved ones, or anyone around you.
In general, when a lithium-ion battery catches fire, you can take the following three steps:
Use a fire extinguisher:
Depending on the size and type of the battery, there are several methods to extinguish a lithium-ion battery fire. You need to react quickly and prevent the fire from spreading.
Since fires caused by lithium-ion batteries are classified as Class B fires, you should choose a standard ABC or dry chemical fire extinguisher. The Class B classification is intended for distinguishing flammable liquids. As lithium-ion batteries contain liquid electrolytes, they fall under this category.
When burning, toxic liquid acts as a conduit for the fire, aiding in its rapid spread.
You can use the fire extinguisher to spray the flames until the fire is extinguished. The steps are as follows:
Pull out the safety pin to enable the use of the fire extinguisher.
Aim the nozzle at the base of the fire.
Squeeze the handle firmly.
To ensure the flames are completely extinguished, sweep the nozzle back and forth at the base of the fire.
Take the battery outside the building:
If you suspect any issues with the battery, such as excessive heat, liquid leakage, or unusual noises, you should place it in a safe, open outdoor space and wait for the battery to return to normal. Note that you should not attempt to handle a battery that is on fire or leaking, as it may pose a danger to you.
If the battery catches fire, wait for all the batteries to burn out, and then attempt to extinguish the fire.
Call the fire department:
Fires caused by lithium-ion batteries fall under the category of thermal runaway incidents. Subsequently, a fire involving an electric bicycle battery can present multiple hazards, such as toxic smoke, flames, and metal projectiles. After taking the necessary measures mentioned above, if you are unable to control the fire, contact the nearest fire department in your area.
Assess the severity of the situation and avoid approaching a burning battery. If you are not comfortable handling the fire, wait for the firefighters to arrive.

Electric bicycles have the potential to change the game by reducing our reliance on cars and transforming the way we commute. However, while accidents are rare and shouldn't discourage you from investing in an electric bike, it's important to be aware of the potential fire hazards associated with large lithium-ion batteries installed on the bike frame.
Lithium-ion batteries offer many advantages that make them an ideal choice for electric bicycles. They can be charged and discharged hundreds of times, are relatively lightweight and compact, and contain lower levels of toxic heavy metals compared to many other battery types. Unfortunately, they are also highly flammable.
Why do electric bicycles pose a fire risk?
The lithium-ion batteries used in electric bicycles consist of two electrodes separated by an electrolyte. During charging or discharging, charged ions move from one electrode to the other.
The electrolyte in lithium-ion batteries is highly flammable. While this is generally not a problem, if the battery is damaged or overheated, the liquid may ignite. Once one battery overheats, adjacent batteries can also overheat (a process known as thermal runaway), and the heat and pressure quickly become uncontrollable, leading to an explosion.
To understand the reasons behind such incidents, TechRadar interviewed the Fire Protection Research Foundation, the research affiliate of the National Fire Protection Association (NFPA).
The project manager at the foundation explained that there are various causes for lithium-ion battery fires, including manufacturing defects, design flaws, improper usage (such as placing the battery near a heat source or exposing it to prolonged direct sunlight, which can lead to overheating), puncturing the battery in a way that causes a short circuit, and using chargers that are not suitable for the device.
These issues are not unique to electric bicycles—any device with lithium-ion batteries can potentially catch fire, as we have seen with smartphones, laptops, and electric cars.
Hoverboards, in particular, have gained notoriety. Since their popularity surged in 2015, the U.S. Consumer Product Safety Commission (CPSC) has reported over 250 incidents related to fires or overheating. Major airlines have banned hoverboards from commercial flights, and retailers like Amazon, Overstock, and Toys "R" Us have temporarily halted sales.
Electric skateboards are particularly susceptible because they are relatively new and lack design standards that mandate safety measures such as venting holes or separators that act as fuses and shut off the battery at certain temperatures. Unlike other devices with lithium-ion batteries, they have not undergone rigorous testing before being sold to the public.
The U.S. Consumer Product Safety Commission swiftly implemented safety standards for hoverboards, and although their use on airplanes is still prohibited, hoverboards quickly made a comeback on store shelves.
Electric bicycles have been around for a long time and have more mature standards. However, the Fire Protection Research Foundation explains that bicycles involved in fires often have poor manufacturing quality:
"According to anecdotal reports from some fire departments, such as the New York City Fire Department, many electric bicycle fires are caused by low-quality components (such as poorly controlled batteries or products not certified by independent testing laboratories)."
How to prevent electric bicycle fires
In addition to purchasing electric bicycles from reputable manufacturers that meet appropriate safety standards, there are some measures you should take to maintain your electric bicycle and prevent fires:
Read the user manual and follow the manufacturer's safety precautions.
Only use chargers provided by the brand that are compatible with the battery.
Avoid using power extension cords; plug the charger directly into a wall outlet.
Ensure you have smoke detectors installed in the area where you charge your electric bicycle, and that you can hear the alarm. For example, if you charge your electric bicycle in a garage or garden shed, make sure a smoke detector is installed there and can be heard from your house.
If your battery or electric bicycle is exposed to a flood, consider it permanently damaged and do not attempt to charge it. Dispose of it responsibly.
Thorpe also suggests considering recycling the battery of your electric bicycle after five years, regardless of its usage. "Electric bicycle technology is changing and advancing each year," he says.
Lastly, he warns against keeping old lithium-ion batteries at home—whether they are from electric bicycles or not. Instead, responsibly recycle them.
The National Fire Protection Association (NFPA) has its own safety tips for lithium-ion batteries, providing information on the safe use of products powered by lithium-ion batteries and guidance on what to do in case of a lithium-ion fire. It also offers specific guidance for electric bicycle owners, including:
Do not use aftermarket batteries.
Always use the power cord and power adapter specifically made by the manufacturer for the device.
Do not leave the electric bicycle unattended while charging.
Do not leave the electric bicycle charging overnight.
Store batteries and devices at room temperature. Extreme heat or cold temperatures can damage the batteries. It is also not recommended to leave them in direct sunlight.
Do not keep electric bicycles (or similar devices) in children's rooms.
Do not block main exits of buildings with electric bicycles (or similar devices).
What to do in case of a fire
Pay attention to the battery of the electric bicycle, as you may be able to identify warning signs before a fire occurs. If you notice strange odors, changes in shape, leaks, unusual noises, or excessive heat, NFPA recommends moving it away from anything that could catch fire (if possible) and calling the fire department.
If a fire does occur, do not attempt to extinguish it yourself; lithium battery fires are particularly hazardous as the battery casing can explode at high temperatures, posing the risk of flying debris. Instead, evacuate the area immediately and call emergency services.
By following the safety guidelines above, the risk of a fire is minimal, which should not deter you from purchasing an electric bicycle. However, if a fire does occur, leave it to the professionals.
