Lithium Battery Charging time?
russian_sweetie13 asked:
My lithium battery for my video/music player wont charge. I left it plugged in the computer for 7 hours, and it says it hasnt charged at all. The computer was on, not on standby or hybranation, but on. Does it matter whether i leave the player on on off? because it seem to be charging a little when the player is on, it ran for 3 minutes. and then died.

Also, can i charge the player with a cell-phone charger, or will it not work just the same?
As you said, your computer needs to be on so that it can supply the charging voltage to your music player’s battery. If you’re hooked up to the USB port, there’s no choice, you music player WILL turn on in limited mode so that the battery can recharge.
If it’s been charging for 7 hours and runs for only 3 minutes, then I’m afraid your battery is done with. Which is a problem I have with all the music players now using those lithium batteries. They drain quickly, even when not being used, and they don’t seem to take very many charges before dying out. And when they do run down, you can’t temporarily stick in an alkaline battery while the lithium one is recharging.
As for using a cell phone charger to recharge the music player battery, there are different ratings and you may well damage your music player by using the wrong one. I don’t recommend it. Buy the proper charger from the manufacturer if that’s what you want. But your USB should do just as good a job.
I’m afraid Marc is correct. You will need to replace the battery; or failing that, the whole player.
But here’s a tip. The worst thing you can do to a Li-Ion battery is discharge it deeply & then recharge it a higher currents at the beginning. A intelligent charging circuit won’t do that, but your player’s charger may not be that smart.
So the tip for your new battery is this: Don’t ever discharge it more than about 80%. Always leave a little juice in the battery and it might last a whole lot longer.
Also, don’t ever use any charger other than the one that comes with the player.
