how long do I charge 9 cell?

I am supposed to receive my 4:3 screen T61 today and I've ordered 9 cell battery. How long should I charge it for most effective use?

When purchasing a new battery, you may find that the battery is at or near 0% capacity. This will be due to the length of time the battery has been in stock and does not affect the quality of the battery. If the battery is at 0%, it may take up to 12 hours of continuous charging or, cycling the battery three times (see the Battery conditioning section below) to wake up the battery. If the new battery still does not have a charge after having been charged for 12 hours or cycled three times, it should be replaced. Standard warranty on all ThinkPad batteries is no more than one year as stated in the Statement of Limited Warranty that comes with the machine or battery.
