Battery cycle count
My Macbook Pro 13" early 2011 8,1 battery is not lasting very long, usually a couple of hours and most of that time the lid will be closed. I don't watch films on it, maybe a half hour on iplayer, only surf google etc. The cycle count stands at 561 and it states 'Service Battery'. The count seems low. Is this normal and how much does it cost to replace a battery? Thanks. Jon
