M17xR3 Battery ???

Hey guys I just wanted to know whether the battery in the new alienware m17xr3 models is a 'smart' battery or not ? Do i keep it plugged in all the time or do I disconnect it when it reaches full charge ??

I remember I completely ruined the battery on my old laptop because I did not unplug it after it was completely charged so after about a year of doing that the old laptop would run for about 10 minutes of the battery and then it would die again. I just wanted to make sure I do not kill the battery on this laptop like that.

 

Thanks in advance for your answers

Generally, now-days (since those laptops caught on fire a few years back) most Lithium laptop batteries are smart-charging to prevent over-charging.

Unlike Ni-Cd and Ni-MH batteries (who should be cycled down near zero to prevent a life building up) ... it's generally recommended to keep them fully charged always (or when-ever possible). Charging partially depleated Lithiums is fine. In fact, if they ever get too low, they might be damaged.

Pretty sure Tesla is saying yes, without saying it.

If it's Lithium-Ion or Lithium-Polymer (which I'm sure it is) then yes.

However, I would still run it on battery 3-4 times a month to "exercise" the battery.

Whether or not it has a true "Smart Charging Circuit" I wouldn't dare to guess (after all ... you are looking for a definite answer) but I bet Dell-Chris_M could find out for you.
