Lithium Battery Faults

[mickthemaverick]

SWMBO dropped her phone on Saturday evening and it went completely dead. I put it on charge and there was no indication of chargeing at all and it still wouldn't power up, and nothing changed after two hours. On removing the battery with the charger still plugged in the screen began to flash the Android symbol you usually get when you first power up so I suspect the phone may be ok but the battery dead. With my multimeter on its lowest dc voltage scale there is a very solid reading of 0 volts across the battery terminals so it looks like the battery has died completely. I suspect a possible internal connection fracture since it was working fine at the moment she dropped it. So has anyone else come across this type of battery experiencing a complete sudden failure?

IN my research into this issue I came across this video discussing the manufacture of Lithium cells and I thought it was well done:

No.... but I'd be tempted to leave the phone outside in case it has a 'thermal event'

I have removed the battery and put it on the tiles outside for that very reason!
