Your installer just left my driveway a short time ago. Before he left I advised him that I would be contacting you in the following regard. My vehicle is a 2021 Ford Explorer. When I first purchased it and looked under the hood I was shocked that I did not see a battery. So, doing what I do best, I googled the subject and discovered it was enclosed by the firewall. I had more recently considered replacing the battery myself and had seen numerous videos on the subject. I elected to change it now because the vehicle was starting to have some electrical anomalies. I contacted 1-800 Battery because I had had a good experience several years ago (previous vehicle). When your installer arrived I already had the hood up. Apparently he did not see a battery so he stood by the tailgate and asked me if the battery was in the back. From there, I’ll cut to the chase. Basically, I became the installer’s second set of hands and nothing I’ve seen on the videos say it’s a two person job. I held the hood up, fully extended, for an ungodly amount of time and at first was holding both the hood and the top of the enclosure. When I raised my concern they issued me a mere $20 credit. At a bare minimum the entire installation part should have been refunded. My explorer and I provided the guy with On The Job Training.
