|Look at the date on that article, it's dated over 10 years ago. Technology has improved much since then.|
Also look at what it said for lithium ion batteries - Lithium-ion
Lithium-ion batteries have excellent capacity for their size and weight. They also do not have many of the problems that other battery types do.
Meaning they do not have a memory effect.
Here's another excerpt from that site about lithium ion batteries, look at the last sentence - NiCad batteries are especially prone to this problem. Therefore users should try to discharge the battery fully after each use, a process called conditioning. NiMH batteries are less susceptible to the memory effect, but even then you should condition them once every one or two weeks. Li-ion and Li-Po batteries are immune from the memory effect.
And they don't give the complete story when they say charging cycles. They are talking about full 100% discharge. There is no magic number for the amount of times a battery can be cycled, again, it depends on how much you discharge it.
