QIKPAC batteries are initially delivered in Sleep Mode. This is also the state the battery enters if it has been discharged too far. The battery will automatically exit Sleep Mode when it is charged. You can also enter/exit Sleep Mode manually if you wish the battery to be place in long-term storage by pressing and holding the orange button for five seconds. If multiple batteries are connected together, each one will need to be put to sleep separately, but only one battery button needs to be pressed to wake them up.
