Hi my name is ***** ***** I will be the expert working with you today to help resolve your problem.
in what device are you trying a new battery
the problem is now with the battery, try ti use a cotton swab dipped in alcohol and try to clean the contacts inside the camera battery case
if you have already tried that then the problem is with the cameras internal board which consumes battery power the circuit has to be checked.
how old is the camera?
is it under warranty?
I am sorry to say the camera needs a repair there are components on the circuit board which needs to be replaced that handles power section like semi diodes and capacitors.
we can only tell you by our experience with the devices as you know that the camera is a compact device and it doesn't have user accessible parts which can be removed and replaced they are all sensor based so we either replace it or repair it. I hope that makes some sense.
New camera price is £99.99 inc VAT
Repair will cost £50.00
choice is yours.
