Why Do LiPo Batteries Get Puffy?

Are puffy batteries dangerous?


Removing a swollen battery can be hazardous, but leaving a swollen battery inside a device also poses risks.

To prevent potential device and bodily harm, a device should not operate with a swollen battery..

How do you keep LiPo batteries healthy?

Lithium Polymer must be CHARGED and STORED in a fire-safe container like a Lipo Sack. Do not charge batteries near flammable items or liquids. Keep a dry fire extinguisher nearby or a large bucket of dry sand, which is a cheap and effective extinguisher. Never charge inside an automobile even when parked.

What happens when you overcharge a lithium ion battery?

The control system prevents overcharging, which can cause the lithium ion battery to overheat and potentially burn. This is why the Li-ion batteries are more expensive. The only way for the Li-ion battery to overcharge is if the charging system malfunctions, and then the battery will heat up while in the charger.

Why are LiPo batteries dangerous?

LiPo batteries can be highly dangerous, and many people have no idea! For years, lithium polymer batteries (LiPos) have been known to be dangerous and unpredictable. Dropping, denting or crushing can shorten the life of the battery and even cause an internal short — a recipe for fire.

Is it normal for LiPo batteries to swell?

As we just found out, LiPo cells can & will swell. It’s actually somewhat normal as they age since electrolyte decomposition is occurring all the time.

What happens if you over discharge a LiPo?

During a reasonable or slow discharge, however, LiPos will not catch on fire, even if discharged all the way down to 0V/cell. … Below ~3.0V/cell the damage becomes significant enough to care about. Below ~2.5V/cell, most manufacturers of LiPo chargers have said that the battery is too dangerous to be recharged.

How do I keep my battery from swelling?

Here’s how you can prevent a swollen batteryLithium-ion and polymer batteries despise heat. … If your battery or the device is not going to be used for a long time: store it in accordance with the instructions in a cool and dry place.Use the charger that comes with the device. … Replace used batteries.More items…

Can you revive a dead LiPo battery?

Connect the main plug of your LiPo battery to your NiMH charger and start charging at the lowest current possible. Typically this is 0.1A. … This will take longer than charging at 1C but is safer. Once the balance charge has completed balancing you should have a fully recovered LiPo battery.

Will a bloated battery explode?

According to internet tech website Wireless Rev: “If at any point, you realise that your battery has swollen you need to get rid of it immediately. Your swollen battery can leak and damage your phone or it can even explode and start a fire. … Lithium Ion batteries don’t react well to overcharging at all.

Why do lithium batteries explode?

Most lithium-ion battery fires and explosions come down to a problem of short circuiting. This happens when the plastic separator fails and lets the anode and cathode touch. And once those two get together, the battery starts to overheat. … Other external factor can cause a lithium-ion battery to fail, too.

What causes batteries to swell?

Common causes of battery swelling include: Overcharge conditions which accelerate parasitic reactions between the electrodes and electrolyte, with release of heat and gases. … Mechanical damage to electrodes induced either during cell assembly or from the product application.

How do I keep my LiPo battery from swelling?

Tips to avoid swelling on your LiPo batteriesUse quality chargers. If the official charger that comes with your battery or device originally costs $50, then don’t use a cheap $5 charger. … Don’t over-charge or over-discharge. … Replace old batteries. … Avoid mechanical damage. … Don’t store in a hot location.
