ethornley Posted June 21, 2007 Report Share Posted June 21, 2007 Hello all, Is there any reason why I should not leave my RH1 or any MD unit permanently attached to the computer via the USB port? Can the lithium battery be left in the unit? Is there any danger of an electrical spike from a thunderstorm etc. travelling up the USB cable?Thanks,ET.

Sparda Posted June 21, 2007 Report Share Posted June 21, 2007 You would kill the battery - it would be trickle charging 24/7. The unit itself plugged 24/7, I don't think there should be a problem. Just leave the battery out. Oh, and if there was a thunder storm, I think your computer would fry first, I would worry more about that. You could buy a surge protector for your computer and accessories. Quote Link to comment Share on other sites More sharing options...
raintheory Posted June 21, 2007 Report Share Posted June 21, 2007 The OLED would probably go bad quicker. Quote Link to comment Share on other sites More sharing options...
Strungup Posted June 21, 2007 Report Share Posted June 21, 2007 Sparda hit the nail on this one ,... definately Take the Battery out , if you leave it plugged up ther would be no problem other than the Battery. Quote Link to comment Share on other sites More sharing options...
culp4684 Posted June 22, 2007 Report Share Posted June 22, 2007 (edited) I actually thought li-ons thrived by keeping them on full charge. I believe I read that somewhere in a discussion either here or the T Board. The li-on system is designed that the charge is regulated because overcharging could actually cause serious problems. I'll have to see if I can find the link.Anyhow, supposedly any unit that uses a Li-on can be stored right on its cradle or charger. My MZ-E10 has spent most of it's four year life this way and still runs longer on a single charge than any other player I have. I also do the same with my HD5.However, maybe keeping it plugged in through your computer is different. I usually just keep my RH1 plugged into the AC/USB adapter...

I usually just keep my RH1 plugged into the AC/USB adapter...My laptop keeps its LiIon topped up all the time. When it drops even a smidgen the charger brings it right up. Maybe the laptop disconnects the battery when charged. I do not know. I would guess SONY would have a circuit to do that in the RH!. Best way to find out: write SONY.Cheers FWIW - My RH1 dims and then the lights turn off when it is hooked up to the charger. I guess SONY thought about this.
