[QUOTE="pigoo3, post: 1527367, member: 56379"] Max. cycle count on these batteries is 300 cycles. Anything beyond this is "bonus round"...where total runtime on a full charge will start to get less & less (compared to what was claimed by Apple when the computer/battery was brand new). I think that this "Service Battery" message may come up automatically when the battery gets to a certain cycle count...or the total possible mAh value (when fully charged) dips below a pre-defined threshold. Long story short. As long as you're getting acceptable total runtimes on a single full battery charge (for your needs)...you can just keep on using the computer. For example...I have an old white MacBook that has a battery that has 600+ charge cycles. I still get 1.0-1.5 hours of total runtime from a fully charged battery...and that works just fine for me...since I use the computer plugged in most of the time. - Nick [/QUOTE]
