If the battery runs out, do not store the amplifier with an empty battery. If you do this regularly the battery life will be shortened. If it is drained and you do not intend to use the amplifier then make sure that you recharge the battery for at least half an hour. Similarly it is not good for the battery to be fully charged and then not used. The optimal level of the electrical charge of a battery that is not being used regularly, every 2 or 3 hours, is below the full charge level, something around 80%, that means 4 hour playing time if the amplifier is new and holds 5 and half hour of playing time charge. If you use the Continental sporadically, once in every few days or more, then keep the level of charge at around 2 hours of the playing time, let's say between 1 and 3 hours. Recharge the battery to full level before the use.
Take into account the impedances of the headphones that you use. The battery will discharge faster on the low impedance headphones and slower on the high impedance headphones. On Beyerdynamic T1, which has a 600 Ohm impedance, my over one year old Continental V2 lasts 5 and 1/4 hour and on 40 Ohm headphones it lasts at least half an hour less.
