    Both are safe lol!

    You need to run it on battery at least every now and then so that the battery will remain capable of holding charge, otherwise if you dont use the battery for a long period of time you will notice the health and charge retention begin to drop. The mac is great with battery life, its made to be portable and run on the battery (as all laptops are), so you should have no fear using the battery until it is almost depleted, and then plugging in the AC to continue using the mac while it charges. Mac batteries have stupidly long lives, have a look at mine below, its been nearly a year now. The battery cycle represents the number of times the battery has been run down to 0%. It is accumulative, so for example say you run your battery down to 50% then charge it back up then run it down to 50% again, that counts as a ful run down to 0% and is one cycle

    Use the AC power all the time, the rare times it gets disconnected or when the power goes off is likely quite enough to cycle the battery, or do it yourself at least once a month.

     

    Mine is 18 months old, has only 13 cycles and shows 98% max filled, however others have shown higher cycle counts and less fully charged amounts.

     

    So I would suggest once a month cycle would be the best course of action.

     

    Since the machine is more likely to die in 4.5 years (average) the original battery will likley last the entire life of the machine.

     

    The serious problem is dust bunnies connecting on the exhaust vents behind the fans, this is a major problem along with other issues Mac portables have.
