Depending if the housing is empty or has the camera inside and also if it has the macro port or the big wideangle dome port attached, it will need different number of pumping to get the green light. It is physics. After getting the green light steady, pump once more (when the internal pressure is too close to the limit to turn orange, it might give you false alarms, as was said before on this or similar topic)
Never go diving without the protective cap. When ever you take out the pump, always put the protective cap before doing anything else to avoid to forget to put it.
Regarding the battery life, if you have one new battery, it should be enough for the full week of diving. But always have with you spare batteries (1 or 2). Sometimes the newbattery is not really new or fully charged or is faulty. And in that case you can save the rest of the dives. When the battery is low power, it might give you false alarms (also als states on some posts on the forum)
