How do I avoid a swollen battery?

Batteries are consumable, and no matter how well you take care of them, they will eventually need to be replaced. You can never be sure that your laptop battery will never swell – it can happen to any device. You can make sure you’re using your device in a proper way to minimize the risk of damage. Here’s what you can do:
1- Don’t leave your laptop plugged-in. charge the battery properly (do not wait until it’s completely discharged, do not leave your device connected to a charger all day). Lithium-ion batteries are meant to a cycle of charge and discharge. Keeping them plugged in all the time stops them to use the capacity and hence its cells can enter into sleeping state.
2- Use the correct power charger with parameters compatible with the laptop. Finding a cheaper version of your laptop’s charger may seem like a savvy money saver but having the wrong charger can cost you in the long run which may not have a same power output which can damage the battery.
3- Replace the battery immediately if its damaged or not performing as it should. there is a standard life span of a battery so don’t expect more from it, replace it immediately.
4- Store the device in a cool, dry environment. .When you are using a laptop, you can use a radiator. Or put a wet towel at the bottom of the notebook and turn on the air conditioner, try not to block the vents on your laptop when you are using, and try to keep the battery cool. Always keep it away from flammable materials and high temperature conditions.
5-avoid overheating. always note the battery condition – if you see it’s overheating or drains too fast, consider getting a replacement
6-This is especially important when using the device for the first time. when you get a new battery, please insert adapter before the battery is completely discharged. Wait for the device to turn off before you start charging the battery.
7- If you want to leave the laptop idle for a long time, please remember to remove the battery and store it separately.
