The spring needs to be inside, it's purpose is to to force the battery(ies) to meet the cap. It is not too difficult to insert batteries in it, even if the pen requires several flat batteries. You just have to insert a battery, one at a time, then keep your finger on the battery, to keep it from dropping. Then you slid another battery under your finger. You repeat this until all required batteries are in the pen. Keep holding your finger on top of the opening.
Then comes the tricky part: you have to slid the cap from side on the battery, replacing your finger. If this does not work for you, you can use the blade of a knife to hold the batteries in, flat on top of the tube, and then let the cap slide in and the knife-blade slip out.
Do notice, that all the flat batteries have to be oriented same way. Most commongly flat side towards the cap and the 'bump' towards the tip of the pen.
