Support , I know the battery spec is 13600mah , and it's nice to know the size measurements, and the Autel in house part number that can't be bought , but what is the battery manufacturer name and their part #, so we can buy a spare battery direct from the manufacturer before it is no longer made, and we are forced to get a new tablet or piggy back a 12 volt battery to the back of the tablet, 2 or 3 years later?
