    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:

    As with any rechargeable batteries. It's always better to charge them first before you use them.

    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 :(

    and now it's down to 81% from 85% in less than a half hour!

    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.

    Did you follow the link and read the thread? Or did you just the thread title?

    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.

    No, it is not a defect. It's normal that it doesn't show 100%.
