Charge Li Ion batteries often?

From this site:

Li Ion

“Charge the Li-ion often, except before a long storage. Avoid repeated deep discharges.”

I’m so used to the old kind, that it never occurred to me to research exactly how Li ion batteries should be treated.

Aargh. Most of my toys now have this kind, and I’ve been repeatedly draining them. I’m so used to those warnings about that.

Anything else I should know?
