iPad Battery Replacement Mackay

iPads are thin. Especially those such as the iPad mini 4, iPad Air 2 and the iPad Pro series that have the LCD and digitiser (touch screen) stuck together to make them a single thin assembly. iPad batteries are usually about 3mm thick but once in a while we see one like this:

And another view:

The lithium ion battery on this iPad Air 2 is made using two distinct cells, the lower cell has experience what’s known as electrochemical oxidisation of the electrolyte.

Simply put, the chemistry of the battery has been compromised and the normal chemical reaction that occurs every time a battery is charged and discharged has been compromised.

Q. Why has my iPad/iPhone/Samsung/Navman/etc Li-Ion battery swollen up like this?

A lithium battery will swell like this for a number of reasons. These are: overcharging, faulty battery construction and excessive heat.

iPhones and iPads have precise charge monitoring circuitry inside which largely prevents the overcharging problem and the manufacturing process is very stringent which makes that cause of failure rare but still occasionally occurs (*cough* Note 7 *cough*)

Which leaves us with the most likely candidate for the battery failure: Heat.

The number of phones that have been left on the dash and swollen up, popping out the screens is astonishing. Even leaving an iPad in a school bag in direct sunlight can be enough to trigger the swelling effect.

Q. Is it dangerous? Should I be concerned?

Not really. Batteries are manufactured in such a way to prevent the venting of toxic fumes and also include data lines which measure the battery cycles and temperature to prevent the battery from catastrophic failure or thermal runaway.

Q. I have noticed my iPhone seems to be thicker than usual, should I get it checked out? Is a new battery expensive?

 

Definitely get it looked at. Batteries are usually fairly cheap with most coming in between $50-$70. The cost of not getting it looked at could mean the screen being damaged which can push the repair bill into the hundreds of dollars depending on what device you have.

Q. Could it be my charger that has killed my battery?

 

Very unlikely. The iDevices have built in circuitry that will decrease the amount of power drawn from the charger as the battery % increases and will finally stop taking charge altogether when the device reaches 100%.

Which means that old wives tale about not leaving your phone on charge overnight because it is bad for it? Totally busted.
