Since the Lith Ion Batts don't have a memory like the old NiCad Batts did it won't make any difference however they are rated for 300 charges so I would suggest you run them till dead so you get the most life out of them. YMMV :2c:

300 charges.. egad.. I've been plugging these things in 3x a day for almost a month now.. and my pass throughs.. I wouldn't know how to count those charges

The 300 charges means 300 charges from empty to full, but if you charge it from half way dead it only counts as half of one of those 300. So it really doesn't matter when you plug it in.

You beat me to it, LOL. From what I have read there is reason to believe that charging a lithium based battery before it reaches a normal discharge state may actually extend it's life past the "300 cycles" point.

On the other hand, you shouldn't leave them plugged into a charger after they have reached full charge. There is always a fire hazard to worry about. I've also noticed that 65/78mm batteries continue to draw current after the charge light goes out. Lithium ion batteries can be damaged by trickle charging. I'm not sure if the battery itself is getting that current or if it's a result of the charger circuit in the battery, but to be safe get them off the charger once they show they are charged. X2 batteries don't exhibit that behavior, nor does my mega PCC, but it is still a good idea to get them off the charger once they are charged.

Just my opinion, worth what you're paying for it, your results and mileage may vary, no warranty or guaranty is expressed or implied.

I don't usually wait for the blinking LED. I usually recharge when the carto needs refilling. I charge them all at least twice daily (I need them all to get me through the day - don't have that many) and my first one died after 11 months. So what is that, like 670+ times? Some of them are over a year old and still work well.

I read somewhere that you wanna be sure to remove them from the charger within 8-9 hours after they're done charging - otherwise, the time they remain charged gets permanently shorter and shorter (something about "plating" inside the battery maybe? Don't really remember the details now). But like Awesum says, as soon as you can would be best for safety.

I'm pretty good at unplugging them when they're charged up. Hubby told me yesterday that he thinks if I pull the usb charger from the puter and don't unscrew the battery from it that leaving it plugged to just the usb thingee would discharge the battery without actually using it.
Wouldn't want to waste a charge like that.

Leaing it on the USB dongle shouldn't, and I stress the word shouldn't, discharge the battery in any signicficant manner. There is a diode, one way electrical gate, the is used for charging to prevent that from happening. Some very slight "reverse current" can flow, but it is so low as to be unimportant unless there is something wrong with that diode. Since the air switch or manual switch, depending upon what type of battery it is, is not being acivated there is no current flow.

As a general rule, I would recommend getting a wall adapter and never plugging anything into your computer you don't have to. Better safe than sorry as easy as it is to charge these.

Look at it this way, which is less expensive and easier to fix, a ten dollar wall charger or a computer that's worth a few hundred at the very least. There have been too many stories of fried USB ports on laptops and desktops. Murphy's Law says that the most expensive part will fail to protect the least expensive part, and it has been proven right too many times.
