The only way to stop the batteries charging on AC power if they need charging is to remove the batteries, if possible. Most tablets cannot do this. On an Apple iPad, plugging the USB cable in to a iPhone charger will show 'Not Charging' on the screen, since it cannot provide enough current to charge the iPad's larger batteries. This is not AC power, however, as it will still slowly drain the batteries if the iPad is used.
The Samsung charge includes features such as a touch screen. Also, another feature is that it has excellent battery power. I have read that while in usage its battery power is 660 minutes, while on standby the battery can last up to 280 hours

no, not even taking 1 out while the other is in, because once the one is out the power is cut off.
old and cold = bad battery
You cannot charge a battery without a battery charger or having it charged by the alternator in your vehicle while it is running.
The time it takes for a phone to charge is largely unaffected by whether the phone is on or not. It might be possible to argue that a phone that is on is using power from the charger to run the phone and to charge the battery, and therefore won't charge as quickly. But the contemporary chargers will generally supply enough power to charge the battery at the "prescribed" rate regardless of whether or not the phone is on. And they'll also supply the power to operate the phone while simultaneously charging the battery at the maximum (optimal) rate.
You ant to charge the lithium Ion battery before the battery reaches a 20 percent charge, so when the light goes red.Charge it while you are playing so you can sit there with no battery loss
If your vechicle does that it means that your battery was dead and after a while of cranking it sometimes it gets charge and starts
A multi-charge battery can be re-charged while your laptop is on or you can use the AC Adapter port to charge while detached from the notebook. An example is the HP KS526AA 12-Cell Multi Charge Extended Battery. It can add up to eight hours of battery life.
This is due to the fact that the Li-ion needs to be charged while the computer is running. The charger will input a higher voltage to charge the battery while the 19v is pushed through a buck converter on the motherboard that outputs a regulated 12v to power the motherboard. This is neccessary to efficiently charge you laptop battery.
Yes.
No, you can charge the battery while it's in the car.
