Should I remove or discharge the battery?

Hi,

I'm using Dell E6400 4 month and the battery shows 94%.
Right now the laptop is always connected to the power supply.

Do I protect the battery by removing it completely?
What is the best option for me according to my usage?

Thanks

If you live in a place where power fluctuates, keep it in and use your battery as a UPS. For more info, read the battery guide...

 

If you must store it, it is best to shelve it with about 40% capacity in a cool and dry place.

This is according to the research of: http://www.batteryuniversity.com/

Lots of information there about Li-on batteries. Happy reading.

 

Please define cool and dry place?

Is it possible to turn permanently the battery into UPS mode?
As far as I know every restart stops the UPS mode.

 

Personally, I store my spare Li-on laptop battery in my desk drawer at about room temperature.

I believe cool and dry is relative, as in, avoid certain spots with high humidity and that potentially get really hot(examples: outdoor tool shed, damp basement, bathrooms, attics, etc.).

Give that website a look, lots of research and information there.

 

I went over this website.
It actually has lots of information.

I'm only using the power supply at the moment and I think the heat that is generated from the power supply reduces the battery life.

I think for my current use it is better to store the battery in the refrigerator.

Has anyone tried it before and can share some tips?

Thanks

 

I have a 9 cell battery for my vostro 1500 which I use as a desktop computer, battery has nearly always been attached with power supply plugged in and computer usually on, suspended, or off, but mostly on.
After about 1.5 years, 14% wear.

I looked at that website also and if the info is good, refrigeration sounds like a good plan, so long as you protect the battery from condensation.

 

How do you suggest to store it in the refrigerator?
Storing the battery in closed box in the refrigerator would be enough?

 

I'd put it in a ziplock bag to keep out moisture.
