Cooking with Lithium | Apple iPad 1st Gen - dead battery revival

Описание: If you have one of the original 1st gen iPads that is completely dead, this video may help you out to bring it back to life! Quite often, if you have an old device that is completely unresponsive, even on a charging cable, chances are the battery is completely dead. In this video we're going to resuscitate a completely dead lithium battery (use the chapters if you want to jump to a specific section)!

There are two different models for 1st gen iPads - A1219 (WiFi-only) and A1337 (WiFi+3G). Both models have the same battery setup. Be careful in using the same approach with other devices though as cell configurations can be different. In particular, if you have multicell lithium batteries that have serial connections (i.e. anything with pack voltages above ~4.5V), recharging over end terminals is not a good idea, you will want to use balanced charging (there are videos on this channel that demonstrate how it can be done).

If you're working with Li batteries, be very careful and make sure you're doing it as safely as you can. There is a mandatory disclaimer that these batteries are potentially dangerous - they can release toxic fumes, ignite or even explode. So don't do it unless you're certain that you can handle scenarios like that. You have been warned.
