If you are an average user, you will probably not even notice it, but it can take up to ten charges and associated use in your device before it can accept a full capacity charge. This is all part of the conditioning process and relatively normal. Once you have used your equipment, put the batteries back on charge, do not let them sit in a partially discharged state for any longer than necessary, and never go out of your way to deliberately discharge, this will only reduce the overall life span, if for any unforeseen reason, they is an extended period where you are not using the batteries make sure they are fully charged first, then recharge every four weeks but do not leave on the charger for more than 24-hours
