Someone mentioned that the L-I battery should be drained

them. I
play Scrabble with a partner. When I pass the laptop to the other
player, I
unplug the AC. When I get it back 5 minutes later, I plug it in
again
during my turn, so as to restore full charge for off-leash work
after the
games are finished. Is this a bad habit?
I mentioned that that is the WORST way, from everything I've read,
to treat a LiON.
Ok, sorry for the lack of clarity at the start of this post, insert a
statement like:
"full discharge is the worst way to treat a LiON" here.
A little google searching will provide many sources for the same info.
In a nutshell, everything I've ever read about Lithium
rechargeables says they should be kept topped up rather than fully
discharged, kept as cool as reasonable especially while charging,
and if you have to store them for a while without use they should
be at 50% capacity and in a cool place.
No matter what you do, even stored and unused, they lose total
capacity over time, about 50% max of original life after 2 yrs is
not unusual.
HTH.
