I’m at the moment staying at my mother and father’, working from my Dad’s outdated workplace. It is a basic outdated workplace, stuffed with extra recordsdata than anybody might moderately want, dusting shelving models with CD demos for Encarta 98, and naturally, the compulsory stack of outdated smartphones.
I believed the outdated smartphones have been enjoyable. It is a stack of outdated iPhone 4’s from years in the past.
However what I really discovered among the many stack wasn’t simply worrying, it was downright harmful, an accident ready to occur: a bulging, bursting, smartphone battery, simply ready for its alternative to burn the home down.

There’s an outdated battery in your own home ready to trigger a fireplace
Why do batteries swell?
Lithium-ion batteries degrade over time via a course of known as electrolyte decomposition. Because the battery ages — whether or not via repeated charging cycles or just sitting in storage — the electrolyte fluid contained in the cell begins to interrupt down and produce gasoline. That gasoline has nowhere to go. The battery’s sealed casing inflates from the within, slowly at first, then extra clearly.
Partial discharging with long-term storage is among the best methods to push a lithium-ion battery to the purpose of swelling. If I needed to guess, that outdated iPhone 4 has been sitting on the shelf on this examine for a minimum of 10 years, if no more.
The iPhone 4 launched in 2010, and my household upgrades sometimes each different technology. The iPhone 6 launched in 2014, so we may very well be speaking 12 years.
Now, on condition that the swelling on this smartphone wasn’t at important ranges, I believe the swelling has occurred up to now few years, that means it sat dormant for a very long time. However as soon as the swelling begins, it is solely going a method.
My mother and father had no concept concerning the dangers of a swollen smartphone battery
Ticking time bomb?
The most important drawback with a swollen smartphone, laptop computer, or some other sort of battery is that it is unstable. As well as, the chemical substances and components used within the battery composition are extremely flammable and likewise extremely tough to extinguish via “regular” means.
If the casing on an outdated, swollen battery is broken, punctured, or in any other case, it could possibly trigger an unlimited response that that produces intense warmth, and may result in in depth harm and even demise.
Even and not using a puncture, continued storage of a swollen battery carries danger. Continued gasoline manufacturing places ongoing stress on the gadget casing. In telephones, this sometimes pushes the display screen away from the chassis. In tablets or laptops, it could possibly crack the chassis itself, exposing the battery additional. The issue doesn’t stabilize by itself.
Recognizing a swollen smartphone battery is comparatively easy
Bulging units are a giveaway
The obvious signal is bodily deformation. A display screen that sits increased on one aspect, a again panel that rocks when positioned on a flat floor, or a cellphone that now not closes correctly on the seams.
On older units with detachable backs, the battery itself could also be visibly rounded or bubble-shaped. On sealed fashionable smartphones, you’re looking on the casing deformation somewhat than the battery immediately.
I’ve additionally learn that at occasions, you possibly can odor the bloated battery, although I’ve by no means skilled this myself. Based on iFixit, in case your gadget battery provides off a “candy, metallic, or acetone odor,” that would sign increasing gases escaping the battery, which is extraordinarily harmful.
You have to get rid of the battery safely and shortly
Not in your family trash
When you discover a gadget with a swelling or swollen battery, do not panic. You do have to get rid of this, however you possibly can’t simply dump it into the family trash assortment.
It must be taken to a particular recycling middle that may cope with lithium-based batteries.
The Battery Community lists hundreds of drop-off places the place you possibly can take a battery for secure disposal, although you might need to name forward and double-check they take swollen cells earlier than you set off.
Equally, iFixit’s E-Waste has a spread of choices for secure disposal, whereas many main retailers like Finest Purchase, House Depot, Lowe’s, and Staples settle for lithium-ion batteries. Once more, in all instances, name your native retailer earlier than you head off to ensure they settle for swollen batteries.

Go and verify now
The cellphone on my mother and father’ shelf had been there for the higher a part of a decade, if no more. No one had considered it, no one had checked it, and no one would have till one thing went mistaken. Previous units have a approach of changing into invisible as soon as they cease being helpful.
I would advise taking 5 minutes at this time to have a fast verify via your outdated telephones, tablets, e-readers, health trackers, and laptops which were in storage. Lay them on a flat floor and take a look at them correctly to see whether or not they’re nonetheless the form they need to be. If something seems mistaken, do not wait to cope with it. The longer a swollen battery sits, the extra unstable it turns into.
