Lipo Battery Puffing Fix-Causes And Fixing Methods
That is why the disposal or discharging of the swollen LiPo battery is considered to be a good practice. It means that the LiPo battery does not cause a fire if it unintentionally attaches to its terminals and forms a circuit.
Several battery manufacturers in the past proposed that LiPo batteries can be immersed in saltwater as a way to discharge them. This method has become heavily challenged, as many users have argued that it was not only ineffective, but dangerous as well. Unloading a saltwater battery is a very slow process that can take up to a few weeks for several days. During this time, the saltwater could corrode the LiPo battery's aluminum terminals, resulting in electrolyte leakage to the water. Since battery acids are normally very reactive and poisonous, this is bad news so it's better to avoid it.
A better way of discharging a LiPo battery is by hooking up its terminals to any device capable of acting as an electrical charge, such as a light bulb or a high resistivity resistor. When you want to use a light bulb, you should be able to discharge the battery very easily with a 20W halogen bulb. To speed up the discharge cycle, you can even hook up multiple bulbs in parallel. You will know when the battery is discharged as soon as the light is no longer lit.
You should carry it to the nearest battery recycling facility once the LiPo battery has been discharged. A battery recycling facility near you can be checked online. When you can't find one, if they provide this program, you can try to ask big electronics stores like Target or Staples. Most waste plants, including spent batteries, can also handle hazardous waste. Don't dispose of anything you do.
Conclusion
In such a lightweight and compact package, LiPo battery technology has allowed manufacturers to provide a lot of power. Nevertheless, LiPo's high power density comes at a price. We are vulnerable to mechanical damage, fire capture, and premature swelling of batteries. It takes a little more care to look after your LiPo battery than your regular lithium ion battery . They should be kept cool, stored in partially charged condition, and secured against physical damage.
