SO I believe i have the original motorcraft battery in my 2011 F150 but I'm not sure. Does anybody know if/where the date would be and how to interpret it? It also appears to have a little green "glowing" window which I assume to be a battery indicator of some type? Mine is strongly glowing green which I would think is a good thing... It does get "topped up" with a digital charger about once a year (before winter). Edit: Ford also recommends a silver calcium SLA battery to function correctly with that dang smart charging system. Does anybody know who/where carries these?
