Oakie sent in this great article by Marshall Brain of HowStuffWorks the does a great job of explaining Lithium-Ion batteries. In case you did not know, this is the type of battery that powers your Berry. I found the description quite interesting and thought I would share. Here are some FAQ points I thought were worthy of mention:
They have no memory effect, which means that you do not have to completely discharge them before recharging.- In fact if you completely discharge the battery you are actually ruining it!
- They start degrading as soon as they leave the factory. They will only last two or three years from the date of manufacture whether you use them or not. This is sped up even further if they are stored at high temperatures.
- If you are buying a new battery pack, you want to make sure it really is new. If it has been sitting on a shelf in the store for a year, it won’t last very long. Manufacturing dates are important.
- A lithium-ion battery pack loses only about 5 percent of its charge per month, compared to a 20 percent loss per month for NiMH batteries.
- There is a little computer in the battery which will shut down the battery if it is completely discharged or gets too hot. This computer eats the 5% every month.
- There is a small chance that, if a lithium-ion battery pack fails, it will burst into flame.

On a side note Alexandre from Blackberry-fr.com (French) let me know about a bad experience he had with his brand new Bolds battery. For some reason his Bold became hot (screen and back) so he took out the battery and put it back 5 min later. After an hour it was completely dead and will no longer take a charge. I really hope this does not happen to my future Bold.

Now i know why my BB shut down for a day after I took it to the beach. I thought it died and was miraculously resurrected.

20% per month? After 1 month, it’s at 80% of max capacity. After 2, it’s 64%. After 3, it’s 51%.
That’s right… with those batteries, you’d get but half the life after a mere 3 months. Takes a bit more than a year to be totally dead. Can anyone say “iPod battery”?

Yeah I found it to be a mind opening read. Now I understand why Apple does not allow for user replaceable batteries. Its a cash cow…
