    I bought this brand new sealed in bad from the apple store. When I opened it the battery was completly dead and I had to recharge it.

    That's not normal, a new battery should have 51% charge, take it back. Somebody has already opened the box.

    Exchanged it, and the new one exact same. Manufactured Feb, battery dead and 4 cycles.

    I'll just keep it I guess.

    Interestingly the battery health on the first was 101% this one 105%

    A new battery usually has 3-4 cycles, sometimes more.

    If the laptop has been manufactured since late 2013, any manufacturing date between then and now can be expected

    The battery drains by itself, and sometimes can be completely drained when you open the package. You should not expect the battery to have any certain amount of charge.

    The battery health is an estimate, and can fluctuate wildly, depending on usage, temperature, etc, etc. It should be taken with a grain of salt.

    4 cycles? I'd say that's pretty normal.

    I'd not worry about how many cycles a battery has and more to the point just wait until it needs to be replaced, i.e., enjoy your computer and not sweat the small stuff.

    I purchased mine several weeks ago. It was manufactured last week of May 14 & had 0 cycles with 81% charge.

    It now has 8 cycles but I wouldn't expect 4 cycles brand new...

    I got a new battery from Apple with zero cycles on it about 2 weeks ago, it still has zero cycles on it :p

    Modern Li-ion batteries should come conditioned out of the factory and don't need any charge cycles for conditioning. They don't ever need to be drained below 50% either.

    Modern Li-ion batteries should be used sparingly and not drained. It's actually running a 100% cycle that damages Li-ion batteries. You will get roughly 300-500 100% drainage cycles vs. 1200-1500 50% cycles, 2000-2500 25% cycles and 3750-4500 10% cycles from a Li-ion battery.

    Use your battery sparingly and only when necessary, when not in use power off instead of letting your MacBook sleep in its bag.

    This is a question, that gets repeated often on this forum and others. Having a couple of cycles is not exceptional, on the contrary.

    A couple of examples:
    New macbook pro has 12 battery cycles
    how many battery's cycle on new macbook pro already had
    New Retina, but 5 cycle count!
    New MacBook Air, 9 battery cycles?
    Etc.
