Purchased new batterys nothing comes on - Cameras

Do you own a multimeter to test the batteries? If not, are the batteries new (Recently purchased)? Please double check the contacts that push against the batteries. Are the contacts clean and push firmly against the batteries? Are the batteries installed correctly? Electronics are polarity sensitive. If you have confirmed that the batteries are ok and they are installed correctly. Unfortunately it may be time for a new timer.

sell battery on ebay and cuck the camera LOL best one I have

If the clicking sound is coming from the engine area, it is most likely the starter solenoid. If you are sure that the battery is fully charged, then you need to clean your cable ends with a small metal brush and a mix of baking soda and water. the surfaces should be metal looking not chalky or green. It sounds like you just are not getting a good connection. You could also replace the two bolts on the cables.

check the battery with a multimeter and make sure that it is showing 24 volts, lots of time the battery comes disconnected under the yellow plastic housing

Buy Ni-cd batteries instead there pretty good.
They are inexpensive, reliable and resist abuse way better than NP-20 because those batteries are poor for high performance applications such as digital cameras.

Good luck

change the batteries or either there's interverence from another product.

An electrical spike  from the battery probally you need to RMA it to HP

try to use another battery and if it does not work please contact the manufacturer to get the camera replaced.
