Battery Concern

I have recently pyrchased a DELL Latitude D830 laptop with a nine cell battery and I have this concern.
I read the http://forum.notebookreview.com/showthread.php?t=91846#post1696317
Battery Guide and also this Quick Reference provided by DELL http://support.dell.com/support/edocs/systems/latd830/multlang/QRG/DA0_BCC/TX419A00.pdf
My main concern is: Would it be better to remove the battery when on AC or not?
Dell mentions having a mechanism which will stop charging when battery is full and i was wondering if the same mechanism is able to prevent cycle loss. So, any ideas/knowledge?

 

The battery does completely stop charging (for a few weeks) when it's full.
However, to last the longest you should keep your battery at 40%. Whether you should actually go out of your way to do this depends on how often you use the battery (if it sits plugged in 90% of the time then you should do something).

Another advantage to removing the battery is that the heat from the running laptop hurts the battery.

 

I see.
In case that the AC Adaptor (by DELL) malfunctions, will the battery regulate any DC abnormalities?

 

Modern batteries have internal chips to stop charging once it's full so it doesn't overload. I usually keep mine on just in case by chance a power outage. Li-Ions don't have memory effects as previous batteries but I've heard not to fully deplete the charge and then recharge as this will decrease battery life.

 

seriously, just leave the battery in the freakn computer.

all these posts and info going around about how to "maximize" your batt life are either based on older batt tech or don't do as much as you think or they say. your battery is gonna start losing capacity after a year or two no matter what you do so just use it, enjoy it and in a year or two when you want a fresh battery, buy one.

 

Which would you rather have, a battery that maybe gives you a few extra months of life, or a laptop that stays on while you're writing your 30 page term paper (which you haven't saved), during a power failure?

 

is it normal to have a battery that starts @ %96 after 2 full day charge?

 

"Normal" is a very broad term.

 

i dont get many power failures so i rather have that extra few months

 

I completely agree. My laptop is always on the mains power whenever I use it. Always. Yet I always leave the battery plugged in. It acts as a UPS, should you have a brief power outage, the battery will take over long enough for you to complete what you are doing and safely shut down.

Remember all it takes is a 1 second loss in power for your entire laptop to switch off, thus reducing the life of your Hard Disk since the head will drop down onto the disc rather then being 'parked'.

Ive always left battery in, with both my work and home laptops, and never had any problems whatsoever.

 

It'll take one power outage and you'll change your mind.

 

Nowadays hard drives do not do this....

Notebooks are meant to be mobile and used on battery. You use the AC power only to recharge the battery (Just like you do for your mobile phone). If you need more up time on battery, buy an additonal extended battery.

 

I have a UPS (uninterruptable power supply), so I take the battery out when I'm at my desk. The heat from the laptop is usually the major culprit that kills battery life for laptops. I've always removed my battery when plugged in at my desk, and the battery for my C610 Latitude that is 5 years old still powers it for 4 hours.
