It was indeed a problem on the earlier TP's (I really burned up a
battery on the TP 750C by leaving it plugged in all the time. It would
drain slowly to something under 100%, then charge back up, drain slowly
again...etc.)
The good news is (a) Li-Ion batteries don't discharge themselves
as readily as NiMH batts do, (b) The "Memory Effect" is significantly
diminished over NiMH batts, and (c) the charging circuitry is smarter now
than it was earlier.
In a nutshell, I haven't had any "kill the battery" problems
since...oh, barring a few odd issues with the 701, since that 750. That
means my 560, 600, and now 1-month old T20, didn't seem to have that problem.
