I can't understand what's said in that text relating with the image nearby. Can somebody explain me?

A discharge cycle is just measured in % percentages, meaning if you discharge(I.e. use your laptop) for one hour and in that time you discharged 20%, then sat it back up to charge back to 100%, it would then take 5 days to complete a discharge cycle of 100%., assuming you only use 20% each day.

Bear in mind, a battery takes "damage", no let's call it wear instead, during charging, think of a piece of wood getting compressed to hold energy, at some point the wood fibers will have become so weak from the repeated compression, that it will just collapse and fail.

And yes, Lithium Ion/Polymer batteries will wear down faster if they remain in the charger after reaching 100%, be it phones or laptops, since they don't come with a 100% shut off capability, meaning the charge will NOT stop completely.

Thanks, I'm clear now for the discharge cycle. But the charger remaining after getting charged up confuses me.
What about the saying here? (under Should I remove the battery when A/C is plugged in section)
http://batterycare.net/en/guide.html#retirarBat

They say, "nothing will happen if the charger remains connected even after the battery is fully charged, problem is the heat from heavy work on the laptop ?

Right, I apologize, if I was a bit unclear.

While the laptop is ON it is okay to leave the charger on and plugged into the laptop, however, when the laptop is off and connected to the charger, then depending on the batteries cut-off circuitry, it will start receiving charge again at 95% to 99%, thus stressing the cells and skewing the capacity "sensor".

General rule* with Lithium ion/polymers, don't go below 25%, don't leave it in the charger over night, charging often is fine when unplugged at 98%-100%, it's something you'd charge it with sooner or later anyways as the energy level drops.

*Disclaimer, those are my own guidelines. :p

Everything's ok. Why not leave the charger plugged in over night (when laptop is ON)? It by-passes battery after reaching 100%. Then why?

You can leave it plugged in while the laptop is on, which is also what I wrote. :p 

Just to be perfectly clear, it's okay to leave the charger in over night when the laptop is ON.

Just don't turn it off and leave it plugged in as the battery will then start charging again when it has dropped 1-5% charge.

I'm not familiar with the program, but reading some of his blog, he seems to know what he's doing and has a good deal of battery experience and knowledge. I'd say it's probably a good program to have, if you want a good idea of your battery's cycles, while getting some easy shortcuts to turn off unnecessary graphical windows animation(s) and effects(Windows Aero) and power-control plans.
