Need help, the other day my battery (P 108) stopped working, I've disarmed and found a diode that had exploded. Replace it and returned to work. But when I saw the voltage on the tester had 20.2v between negative and positive (as seen in the photos) and 20.2v between the center and positive. I have taken the voltage in P107 and values are 8.2V. P108 battery has someone? and you tell me that voltage is between positive and negative please. Diode Exploted Battery P108 i have a Dude With Voltage, I have no other to check Battery P107 I have 3 more, all have the same voltage 8.2
