| Brand new Dell Inspiron 1545 laptop purchased last week. At this time
| the system will be used as a desktop, running on AC power continously.
|
| According to http://www.batteryuniversity.com and other sources,
| leaving the battery in - while always running on AC power and never on
| battery power - will shorten the life of the battery.
|
| So the battery's been removed, and with a 40% charge on it, it's in a
| ziplock bag and stored in the refrigerator.
|
| The plan is to remove it from storage after some time, put it back in
| the laptop, recharge it back up to 40%, and then store it in the
| refrigerator again. This cycle will be repeated indefinitely.
|
| My questions are:
|
| 1. How long can the battery remain stored in the refrigerator before
| it has to be recharged? One month? Two months?
|
| 2. Should I be concerned about corrosion of the contacts or dust
| buildup in an empty battery compartment?
|
| Any help would be greatly appreciated. Thanks!

If you remove the battery while on AC, make sure you use a UPS to avoid 
unexpected power loss and data loss/corruption. Frankly, I would not keep a 
battery at 40% charge because then I'm screwed if I have to use the laptop 
on battery power on short notice without time to fully charge it. I've found 
that my laptop batteries typically last longer than two years albeit with a 
somewhat reduced capacity. But then I don't use my laptop as a desktop 
substitute. If I get 2-3 years of useful life without all fuss of storing 
half charged batteries, then I'm happy. After all, the cost of a new $100 
battery amortized over three years is $0.09 a day.
