Toshiba f 40 Battery Question

(1/1)

coacharnold:
Ok .... there was a recent post about Lithium Ions and 'de-charging" them all the way before recharging.  I have to be honest .... I thought it was better to recharge only after the battery had been worn all the way down. ...  Okay I stand corrected .... but here's some new questions

1 - Does the charge circuit in the toshiba shut off entirely when it's done charging? I.E.   if I plug it in when i go to bed is it safe to have it plugged in till i wake?

2 - Is USB charging OK ....  the player seems to get warm when the USB charging is activated....  then this goes back to my original question ---  does the recharge circuit shut down when the battery is full..... 

3 - I recently updated to the newest Toshiba rockbox ---- it had been almost a year since i did an update .....  does anyone else notice a decrease in battery time?

hope all is well with everyone in Rockbox land ....

1 - To my knowledge, as long as the battery wasn't bought used, yes, it should have a chip that does this.
2 - USB charging should be perfectly safe.

Llorean:
1) Yes.
2) USB charging is slower, this may be why it seems to get warmer, batteries warm up while charging.
3) Do a runtime test against the original firmware, batteries do age with time.

soap:
Listen very carefully to your player before and after initiating a USB charge.
Is the hard drive running the entire charge cycle?
