"Before replacing any lithium ion battery use this trick. If you have one of those food storage devices that sucks all of the air out. Run the battery out, then place it in one of those bags and pump the air out. Put it in the freezer for two days. Then remove it and allow it to reach room temperature. Cut the seal and fully recharge it. If you followed these instructions your old battery will work like new. Warning: this only works if the battery is in a vacuum when you freeze it. And only if you allow it to reach room temperature afterwards before recharging." found on internet.....Also should I remove the battery pack when I am plugged in?? Any of these tips help preserve battery life?
