Ok how annoying is it when you charge something then walk away with it for a little while and then suddenly its already dead or at least half way there! After doing nothing. This involves a few things such as laptops, mp3 players, cell phones, and other pieces of electronics that are on lithium batteries. Technology has moved forward greatly over the past 5 years, but battery technology has not improved that much! That is what they have to work on!
You know when you charge your cell phone and use it for about three phone calls, and when you put it down its beeping like crazy and then it dies! That is probably the most annoying, but what annoys me the most is battery cell memory. Its what happens what you charge your batter too much and then it loses some power in it because you charged it before it was drained. The manufacturers tell you it cant happen but it does, that is why people replace there batteries! Nokia phones are a bit better then before since that they dont decay as fast any more! Some phones are pretty bad phones, but they have improved. My luck has been better with Mp3 players since none of the ones I have had have gone bad yet.
But my laptop is annoying now, since one battery is as useful as a paperweight. And the second one is going down the same road! I took it off the charger and 20 mins later it was beeping! I want to slap somebody who built the damn battery! What the hell were they thinking! Cant they improve this damn technology! And now whats even worse Dell and Sony laptops are blowing up left and right!
