Overcharging?

Can it be done? I put it on charge over night then head out the next day forgetting to unplug it before I leave the house.
 
No Li-ion chemistry becomes unstable resulting in explosion or flame venting if overcharged or over discharged - as you can imagine, manufacturers will avoid this at all costs and have built in circuitry to prevent either.

However, you can great extend the life, or charge cycles, of your battery if you undercharge it (<100%).
 
Once it's fully charged, it enters what's known as trickle mode, where it will charge t 100 and discharge to 95% and continually just do that till you unplug it.
 
not possible & is actually recommended to plug it whenever you can to have better battery life.
 
No you can not overcharge the batteries. They are protected against overcharging. If you charge more than that, you could harm the longevity of the battery.

My iPad 2 is always plugged in and I have never seen it go below 100%. :)

I hope you don't mind me asking, but why do you do this? Some of the best features of the iPad are its 10-hour battery life and great portability. Seems like a massive waste to keep it plugged in all the time.

Also, not letting the battery drain regularly is not good for battery health (although I guess you're not concerned about that, since you keep it plugged in anyway).

I do it more for convenience as I place my iPad on top of my desktop gaming computer and there's an outlet close by that's why it's plugged in all the time.

Yeah I suppose it's probably not good for the battery and i'll need to shake myself of leaving it plugged in. :)
 
If I were to keep my iPad plugged in, won't it promote battery longevity since my battery cycles will be minimized?
 
Just for reference. Idevices, and all devices with lithium ion batteries do not trickle charge. A trickle charger would be something you keep on a lead acid battery that doesn't get used a lot like a motorcycle, boat etc.

Trickle charge is a drop in voltage, so if you have a 12volt lead acid battery it will "trickle" 2 volts or so to keep the battery topped off. Trickle charger on a lithium ion battery would damage it quickly. In lieu of trickle chargers the battery tops off, stops charging, sits and discharges and at a certain point the charger is allowed to send voltage through ago. Its either full on or full off....

Fair enough. :) But yeah, your iPad is probably desperate to go exploring. :p
