Don't forget to follow the instructions in the owner's manual regarding changing the battery and the need to rest the BMS (Battery Management System).

Maintence » CHANGING THE VEHICLE BATTERY » Battery Management System ...

After battery replacement, or in some cases after charging the battery with the external charger, the BMS requires eight hours of vehicle sleep time (key off with doors closed) to relearn the new battery state of charge. Prior to relearning the state of charge, the BMS may disable electrical features (to protect the battery) earlier than normal.

*NOTE: FoMoCo dealership service can reset the BMS using their IDS (Intergrated Diagnostic System) negating the eight hours of vehicle sleep time requirement.

(owner's manual) Don't have one -OR- would like a digital, searchable desktop document?

Why? Sam's Club has a higher rating battery for the 5.0 that costs $120. Imagine there are plenty others out there. Give your truck a gift. Way too many computer related things going on with these trucks to wait for a battery to fail if it can be avoided.
