For the new battery, actually no one will know how rich is your brand new battery, but almost most of the brand new batteries are empty, but few of them may carry a lot. Instruction request you to charge and discharge for few times enable your battery to warm up into top fit condition.
I will try to charge your battery with 2A, then discharge it. To see how much it can be charged!!
You only discharge your battery to know how much amp it was!!
