Why do LiPo batteries swell?
A LiPo battery also has polymer separator that keeps the positive and negative terminals from coming into contact with each other. Batteries swell because of the phenomenon of electrolyte decomposition. As its name implies, this is the process where the electrolyte solution decomposes into its individual components.Is it OK to use a puffed LiPo?
As long as it is very minor LiPo puffing & goes away after the pack cools down, it has been my experience that you can usually still safely use the pack and keep the swelling in check; likely not to its full discharge potential however.Is it safe to keep a swollen battery?
A swollen lithium-ion battery can be extremely dangerous if left in your device. It could become punctured, causing hazardous gases to escape. A swollen cell phone battery could even catch fire or explode while you're holding it, leading to serious injury.What causes Lion batteries to swell?
Lithium-ion batteries use a chemical reaction to generate power. As the battery ages, this chemical reaction no longer completes perfectly, which can result in the creation of gas (called outgassing), leading to a swollen battery.What causes LiPo batteries to explode?
Heat & OverchargingOn hot summer days, there are more chances of LiPo explosion. More exposure to sunlight and high temperatures can be a cause of the explosion. Overcharging is also one reason to catch fire and explosion. So use a charger that is compatible with your battery.

Can you put out a LiPo fire with water?
Small lithium-ion batteries can be doused with water because they contain little lithium metal. Lithium-metal battery fires can be put out with a Class D fire extinguisher. Larger battery fires are best handled with a foam extinguisher, CO2, ABC dry chemical, powder graphite, copper powder or sodium carbonate.Is it OK to leave a LiPo battery charge overnight?
Never leave your LiPo batteries charging while unattended. If a battery starts to become puffy, smoke, or catches fire you need to be able to immediately handle the situation. Walking away for even just 5 minutes can spell disaster.How do I stop my battery from swelling?
How to prevent laptop battery swelling and explosion
- Don't leave your device connected to a charger all day. ...
- Replace your device battery if it's broken or not performing efficiently. ...
- Use the correct charger. ...
- Upgrade your laptop when it's out of warranty. ...
- Store the device in a cool, dry environment.
How do you fix a bloated battery?
The solution is to charge your phone during the day, and by night, put your phone on sleep mode and reduce your phone volume. Another thing is to use the original charger to charge the battery because it was explicitly designed, but another charger complicates the battery.Can you put a swollen battery in the freezer?
Do not put the battery in the freezer. Freezing may cause already-damaged metal components to contract and could cause a short, leading to fire.What do you do with a bloated lithium battery?
Lithium-ion batteries–new, used, or damaged–should only be disposed off via authorized recycling centers. To locate recycling centers near you, your best bet is to use a recycling location index like Call2Recycle or to call your local city/county hazardous material disposal center.What causes the battery to bloat?
Swollen batteries are the result of two things: energy density and heat. The swelling is the result of too much current coursing, in a noncontrolled fashion, inside a cell of the battery, which causes a build-up of heat and gas.Can a dead lithium battery explode?
Lithium-ion batteries are found in many common devices. But under the right (or wrong) conditions, they can catch fire and even explode.How do I stop my LiPo from puffing?
Tips to Avoid a Swollen Battery
- Proper charging – Make sure you charge your battery properly using a quality battery charger. ...
- Don't over-discharge – Make sure you stop using your battery before the voltage gets to the minimum cut-off voltage.
Can swollen battery explode?
Note, however, that until your swollen battery is replaced, you shouldn't connect your device to power or use it. Swollen batteries can explode if not properly dealt with, so you don't want to take any actions that may hasten the arrival of this unpleasant event.Where do you store swollen batteries?
Any swollen, dented or otherwise damaged batteries should be disposed of. Batteries should be stored in a well-ventilated, dry area kept between 40 and 80 degrees Fahrenheit. They should be stored away from direct sunlight, heat sources, and water.What is the lifespan of a LiPo battery?
They give LiPos a typical life expectancy of 150 to 250 cycles. This is because the batteries heat up whenever they are in use, and many people discharge them lower than 3.0V per cell. Physical damage and water may also reduce their life expectancy.Should I discharge LiPo battery before charging?
LiPo batteries also don't develop memory or voltage depression characteristics like NiCd/NiHm batteries, and do not need to be discharged before being charged. But they're not without their downside. Mishandling of these batteries can lead to fire, explosions and toxic smoke inhalation.Do LiPo batteries lose charge when not in use?
When a LiPo battery sits for a long period of time (and not at proper storage voltage), it tends to discharge itself. If it drops below 3.0V per cell, the vast majority of LiPo chargers will not charge it. Sometimes, batteries with this problem can be rehabilitated, but just as often, they are a lost cause.Does a LiPo fire need oxygen?
The lithium-ion battery or Li-ion battery fire does not need any oxygen to burn at all, because it can do that without any oxygen at all. The nature of the fire is recognized as completely chemical, so there is no role of oxygen in it that can start this fire.How hot is a LiPo fire?
The burning lithium creates a metal fire existing at temperatures of 2,000 degrees Celsius/3632 degrees Fahrenheit. Attempting to douse the fire with water is inadvisable since this could lead to a hydrogen gas explosion!Why are lithium batteries not allowed on planes?
Lithium batteries can produce dangerous heat levels, cause ignition, short circuit very easily, and cause inextinguishable fires. That's why renowned aviation authorities, including those in the USA, have banned lithium batteries when traveling.
