I have watched a few youtube videos and it appears some have struggled to remove the housing bracket for the battery.
Nothing much was mentioned on using a battery tender or something like an AC battery charger or how to use to preserve your infotainment settings and preventing your ECU, PCM from "re-learning". For this reason, I take whatever I see on youtube with a grain of salt as it's always incomplete.
From previous experience on older Mazdas and other vehicles, a battery tender is needed, not so much to preserve the radio settings, but to prevent the ECU from re-learning.
Any tips?
