Lost MP3 Player
Trivia brain teasers have some element of trivia in them, but they are not just pure trivia questions.
Ralph was a very disorganized guy. About three years ago, he lost a nice MP3 player that had a lithium-ion battery. Last night, he found it and put it in its charger. The next morning, he found it was still dead.
It was fully charged when he lost it. It had been charging all night. Nothing had broken the MP3 player. Why wouldn't it work?
Answer
If a lithium-ion battery is left unused for a long period of time, it goes into deep discharge. This can cause a battery that charges in three hours normally to take about fifty hours to charge. If left long enough, deep discharge can cause it to stop working completely. Ralph was unlucky to have this happen to him.

| not bad but you can bring back even a dead lithium ion battery using a pulse charger set higher than the voltage of the battery  |

| Just a regular dead one, when it dies in deep discharge, it won't come back, whatever you do.
Thanks for the comments!  |
