Kerri, It is true that with the Nickel Hydrate batteries that they will develop a memory of what the percentage of the battery was before it was plugged in.
The BrailleNote family of products along with many devices are now using Lithium Ion batteries which do not have this memory effect. So, it won't hurt to plug your unit in at 90% nor will it hurt to have it always plugged in. If at any point in time your battery is not lasting as long as it should, there is always the solution to recalibrate the battery. With this, it is recommended to run your battery down to at least 50%. Recalibrating Battery on BT (QT) 1. From Main Menu 2. Press SPACE with O (FN with O) for Options 3. Press SPACE with I (READ with I) for Support Information Mode 4. Make sure the AC adapter is plugged in and press R to Recalibrate. The unit will chatter itself away and recharge/discharge the battery for around 12 hours, so you will want to make sure that headsets are plugged in or put it somewhere it won't be heard. Note: It isn't possible to recalibrate the PK's battery.

I am trying to get into the habit of keeping my AC adapter plugged in unless I go somewhere. Can I plug it back in when I get home if it's say, only 90 percent, or do I need to run it down? Does the bn battery develop a capacity when you partially discharge and plug it in before it's run down, or is it different than say, a cell phone? I didn't know if this battery was a lithium ion or not. Kerri ___ Replies to this message will go directly to the sender.
