do you need to charge the new apple batteries before using?

it says my keyboard is at 55% out of the box and I'm wondering if these are like other batteries that don't charge fully if you don't charge them all the way first?

If they have 55%, you apparently want to charge them first, but don't have to. They appear to be rebranded Eneloops:

...they also hold a charge for an incredibly long time.

I feel stupid for not doing this when I first got them because I was so excited to use my Imac. I used the batteries right away and I charged them last night (after a week or so of use) and they read 85% after charging for 12 hours :(

yes magic mouse. so wait, 85% is normal?!
I bought a $12.00 Rayovac battery charger from Walmart last week, it came with 4 AA and 2 AAA batteries. After the first charge, my Magic Pad and Magic Mouse wasnt @ 100%. I have used only use 3% of the charge so far after heavy use.

I read the link and I just read it again. I understand it to mean the 85 is not a defect. am I missing something?

The low self discharge HiMH cells which come pre charged, should be ok to use straight out of the box without charging for the first time. As I don't think you need to do an initial charge to form the cell unlike the older standard NiMH cells.
