I have a DeWalt DCB107 charger and x2 dewalt 18V lithium ion 1.5AH batteries. I was using my dewalt DSC390 circular saw and drained both batteries, or so I thought, I was only sawing for maybe 2 minutes each battery, I was sawing a fresh 2x4 at an angle so it was under pressure. When I put one battery on the charger the yellow over heat light came on so I tried the other and the yellow light also came on. So I left both sit outside for 10 minutes then tried x1 on the charger, the red light came on and stayed, this indicated full charge, I tried the other battery and it did the same. I tried both batteries in the saw and my drill and neither worked. I tested both batteries with a volt meter and they read 14v to 15v. I read online that the batteries can shut down if they overheat and to reset them place them in the charger for 8hrs, I did this with one battery overnight and it’s still the same.
It seems that the batteries are charged but have shut down!!

Is this possible?
How are they reset?
