Removal and disposal of a swollen battery can be very dangerous. Leaving a swollen battery inside a device can also cause serious harm. This is where our experts at TechRevive in Geelong can help you.   

How to identify a swollen battery?  

Inspect the outside of the device initially. As batteries swell, they naturally expand and push other components out of the way. Often the display button or trackpad will be pushed out of alignment on your laptop.

You may have a swollen battery if your phone case doesn’t fit as well as it used to, or if you notice a new gap between components, buttons may have become stiff or hard to push, or your device feels quite squishy.  You may also notice a sweet metallic chemical smell which could be the battery gas escaping the swollen battery.

What to do if you have a swollen battery?   

If you suspect or have identified your device does have a swollen battery, we strongly advise you not to charge your device as this runs the risk of a fire. Instead, run the battery down as low as you can reducing the risk of fire.

Our expert Geelong device repairer Will from TechRevive doesn’t recommend removing the battery yourself as the battery could be leaking. In the event that the battery does begin to combust or leak, you need to have a safe place to store it in order to get it to us.

Prepare a fireproof container, such as a sealed metal can, metal bucket of sand, or equivalent. Do not use water under any circumstances as the lithium will react with water and cause a fire.

How to take care of your battery?

Batteries are not meant to last a lifetime, and no matter how well you take care of them, they will eventually need to be replaced. That said, below are some good practices to keep your battery healthy as long as you can.

It is important to note that you cannot heal a swollen or defective battery; you can only remove it.

The below tips can only help prevent battery degradation:

1) Leaving your device plugged in forces it to drain and charge many times an hour, which can degrade the battery.

Modern phones have inbuilt power management application system, and they typically have a recharge reminder (sounds familiar, right?). Take Samsung and Apple’s devices, for example—they always alert their users to recharge their phones once the batteries hit the 20% mark. This is the lower boundary limit when it comes to maximising battery health; ensuring your phone battery doesn’t drop below 20% (or below the battery management app’s alert level) is key to improving battery life before it exceeds the manufacturer’s rated charge cycle.

2) Using a non-certified charging cable or adapter risks uncontrolled, uneven, or excessive charging that can cause damage or even result in a fire.

3) High temperatures can also reduce battery efficiency, so try not to leave your phone in the car on a hot day.

4) Avoid dropping your phone as this not only damages your screen but your battery as well. Just like cars, phones are meant to flex during an accident, so even a glued-in battery can bump into nearby components when dropped, resulting in a puncture. Replace your battery if it’s damaged or no longer holds a proper charge.
