I recall that in the past, it was good for the battery to let it run down a certain amount, then let it charge up again. Is that still the current train of thought? My Toshiba laptop is used mostly plugged in to the mains. I note that it never charges more than 80%. My guess is that protects the battery. So, whaddaya think?
Hi Mr. Ed,
That would be normal if you are using the Toshiba Eco Charge Mode option and have it set accordingly:
The TOSHIBA Eco Charge Mode increases the battery life cycles by not charging to full capacity. This mode is recommended for users who most often use the PC with the AC adapter. The battery life per full charge is shorter in this mode. This mode is enabled/disabled through "Battery Manager":

However, to prevent your battery life from shortening prematurely, your owners manual still recommends the following periodic actions:
To ensure that the battery maintains its maximum capacity, operate the computer on battery power at least once a month. The Lithium-Ion battery has no memory effect so it is not necessary to let the battery fully discharge each time. However, for better accuracy of the battery meter, it is helpful to fully discharge the battery periodically. Please see “Maintaining your battery” on page 99 for procedures. If the computer is continuously operated on AC power, either through an AC adaptor or a port replicator (if applicable to your system), for an extended period (more than a month), the battery may fail to retain a charge. This may shorten the life of the battery, and may cause the battery meter to be inaccurate.
You can download your owners manual here for more information:

Hope this helps.
Good luck,
WOT
Thanks, WOT. You've explained it quite well. I'll follow Toshiba's suggestions, as you've pointed out, and discharge the battery ona monthly basis.
The battery on these new Toshibas is virtually impossible for the average owner to replace. My original Toshiba had a very accessible battery.
I have a Toshiba Portege R705 laptop with Windows 10 and have rarely used the battery. Recently, I got popups from Dynamark (Toshiba) to enable the Eco Charge Mode. I followed the instructions to enable the Eco Mode, unplug the A/C, put in the battery and let it drain under 75%. It automatically enable the Eco Mode when battery was drained to 73%. However, I keep getting pop-ups to enable the mode. Your link above is instructions for Win 7 or 8 and doesn't work in 10. How should I proceed?
FWIW, Lenovo also recommends setting max charge on battery in the 75-80% range if you leave it plugged in all the time. The only thing about it I don't like is that you must manually reset the max charge setting back to 100% if (a) you go untethered and (b) you want a fully, 100% charged battery to take into the field, so to speak.
HTH,
