This one is for the hardware specialists.

Is it possible to have a battery that at intermitent times provides the device with less power than it needs? (chokes)

The results of the choke effect would be:
- turning off device without any warning
- freezes
- display flashes scrambled with color lines, possibly coming back to normal or fading to white

I saw some guy saying that you can have crystals being built-up depending on how you charge and the external environment conditions. Would this possibly have anything to do with that?

Last but not least, the final question is... Is it possible to have a faulty battery that has as a fault effect of "choking/power oscilation"?

And if it is possible, is there a way to recondition the battery or it definitly needs replacement?
