Try cleaning and tighten the battery terminals, and then clear the code. If the problem persist the next step is checking the alternator charge. Make sure the alternator is not charging more than 14 volts.

We replaced the alternator and new battery cables and the 2005 ford expedition Triton, still drains the battery by the end of the day. The 4 codes we have are P0113-ff (also, what does the ff mean?)
P0622-FF and P1000-FF. Took battery to oriellys tested said it was good. What next's we need a new battery?? Any advice would be great -
You can ignore the P1000 code. The code mean that your vehicle didn't complete a routine test. The battery was disconnected or die during the test.
The P0113 code is not related to the battery problem.
