True. I had a relatively new battery and, at times, I would forget to turn off my dash cam while at home for a few days. The radar detector would shut off on low battery sensing (Uniden R8) but my dash cam (VanTru N4) would keep going and deplete the battery.
I replaced with an AGM and, lately, on the occasion I still forget, it (the battery) keeps going.
No more bringing out the MaxiSys to reset all of the codes after a battery low issue triggers all sorts of temporary codes. Now, I just do it for fun to reset transient temporary codes from time to time.
