Hi. I have a problem…

Hi all,
New member here.
I have a Cool Fire IV battery that is charged. When I press the button, the green light comes on and the display numbers start going up, but there’s no power. I was using it not long before this happened. I also replaced the coil tonight and used it successfully afterwards.
I’ve tried switching it off as per the instructions – press the button 3 x times then the manual switch to off on the bottom, but still nothing when I turn it back on.
Any suggestions gratefully…
