Thanks for the great write up here. I appreciate you taking the time, as it really help me, and others out.
I didn't go to the trouble of getting a bigger battery, but I did switch from a stock battery to an AGM with more CCA. I invested in the ODBeleven so I could update the Battery fields. Your write was a HUGE help with that.
Glad you got it sorted!!..& AGM even for the same case size has more amps & is just way better in cold temps & way safer in a crash...!!
