Removing battery once fully charged?

Since there's no way to set battery charging thresholds on the E6320 (I've tried with several different BIOSes as well as the "long-life" battery), would it be advisable to remove the battery when the battery is >90% charged and the machine is plugged in? I used to do this back in the day, but then I switched to Thinkpads for a few years and they all allowed custom charging thresholds to be set.

 

Honestly with the latest computers, it really does not matter. Sure it may save you 10% wear per year, depending on your usage, but by the point it really matters, few or couple years later, these batteries would be so cheap new on Ebay anyways. So it just kind of defeats the purpose these days to try to do this.

 

The Dell Precision answers this question for you since the battery contains one of the laptop's feet. (Hopefully they will rectify this clunky design with the next case?)

They also have presets and mine has been left on adaptive which so far (a year this month) registers no appreciable loss in battery efficiency.

 

Interesting. My latitude has no such presets. There are only 2 presets for charging...standard (which charges to 100% every time), or Expresscharge (which also charges up to 100% every time).

What app are you using to see the battery cycles?

I use an E6320 on dock when I am at home. If I am not going to use the laptop on batt the next day I wud just take out the battery. And I also use the media bay batt to give me more hours off the grid. I read somewhere that its not that healthy for li-ion to be stored fully charged for extended period and knowing that heat is also not healthy for batt I do remove it from the laptop when it is gonna stay in the dock for extended period.

 

Don't know about other systems, but by E6540 has some sort of Dell power management utility that comes in to handy, it will only charge the battery up to 90% on certain occasions to prevent battery wear. Had the machine for 4 months so far and no battery wear despite HWMonitor reporting 9% wear, it still charges up to maximum capacity.

 

To tell you the truth it probably won't matter much. I'd be more concerned with the charge rate: fast vs slow.

You might gain a few extra cycles by removing the battery, but it will decay no matter what you do.Still, that doesn't mean you should operate it near the furnace. Us it wisely and under practical conditions and if you get 2 years of continued use you got your monies worth.
