macbook battery seems to be deteratoring quite quickly

on coconutBattery my battery shows 91% capacity (was 92% a few days ago)

its gone though 17 loadcycles and ive had it 2 months.

battery seems to be wearing quite fast :mad:

oh also when i started my macbook it was 0% charged and had a message about the system crashing, strange thing is i could have sworn i shut it down this morning.

my coconut battery says my current battery capacity is 91%. but once before today when i checked it it said 85% was the current battery capacity. it also says i've had it 4 months, which isn't correct...i got it at the end of may. it also says i've gone through 70 load cycles. what is a load cycle?

A load cycle is a complete discharge and charge of the battery. If you only discharge partially before charging, it is only part of a load cycle.
