A capacity 695 means that's all the battery can hold regardless of what you do. The original capacity was ~5600 for a 15" MBP and ~6300 for a 17", so your battery has little life remaining.
Unless you can see a physical defect (swelling, bulging, or leaking), you'll probably end up paying for a new battery
I'm afraid the reality for most of these batteries in the earlier non-unibody MBPs is that they die after a couple of years and less than a couple of a hundred cycles, sportychich324.
My own made it to 18 months and 150 cycles, so you are doing well by comparison!.
Apple's replacement processes at present seem to be:
1) If your battery drops below 80% capacity or shows other signs of being defective (sudden shutdowns, swelling etc) within twelve months and has completed less than 300 cycles, they will replace it free. If you have Applecare they may extend this to three years, though this isn't automatic.
2) If you don't "fit" these criteria then you can buy a battery at reduced price (about 3/4 of normal retail) , but if you do so it will only be covered for a 90 day period.
3) If you purchase a new battery at retail price then they will provide a 12 month warranty similar to that outlined in 1 above.
I really got fed up with this bug. So, I opened my dead Macbook battery, charged the cells with a pro charger. After about an hour, the cells were fully charged. I discharged the cells and measured the capacity. This came out as 3300 mAh, wich is not bad at all for an old battery.
Now my Macbook tells me the battery has 100% charge, but SL still insists the battery needs replacement. Leopard (on another Macbook) is quite happy with the battery and runs almost two hours with it.
Snow takes ten minutes to decide to put the Macbook to sleep. Despite the indicator still being at 100%.
Where's the error? Snow? The SMC controller on the Snow Macbook? I tried removing the power mgmt plist, resetting the SMC, but to no avail. Where's this setting? On the SMbus that talks to the battery processor?
Anyhow, it's not the battery itself. The cells are in a far better condition than Apple would like us to believe. One would almost think this is just a scam to sell lots of batteries.
My Macbook is nearly four years old. It has used up three batteries, one logic board, two harddisks and three power supplies. I'm up for a new one, but I doubt I will buy a Macbook again. Might as well go back to my Cube, my IIci or even the Mac+ that still works. Tho the last option might be hard to use on the net
