yes its unbelievable how much untested crap this people sells. if we were to go to war with china I know 100% I won't be getting shot, their weapon will not fire for sure.
I am really so sorry to keep you waiting for long time. We are still trying to find the reason. May we know this kind of problem happened after the updating?
Long after the update I checked the battery on both of my vehicles. On one the CCA is rate 600 and the AL539b reads 952 at 12.5 volts. On the other the rated CCA is 700 and the AL539b reads 1084 at12.64 volts.
