    Excellent battery. However, if you try to force it into a 5000mah slot it can be done but is hard to remove due to a vacuum that is created so l recommend not using pliers as there is a thin base plate that is only held on by the label and tears off easily. It seems after a 6000mah battery has been inserted and removed from a 5000mah slot a couple dozen times eventually they slide in and out much easier
