i Purchased a new battery from apple for my macbook 3,1 and last night i used it to 80% then because i needed the battery for later i plugged in the wall adapter. Later i notice on istat the battery health dropped from 100% to 98%. I used the abttery the rest of the day and charged it up now i have 92% battery. using Coconutbattery im told this battery sat in the store for about 250 days because it was made in January 2014. How can i get my health back up to 100 like last night? or should i bring it in to apple right away?
