    Hello looking for some information on this code p3023 bank 13 becomes weak . Posting two pictures of the techstream screen of the battery . The bank in question is 14.63V . This is a refirbushed battery about 8 months old .

    looking for opinions and any information on how to go about fixing this. Im looking to get another few months out of this battery without another 600$ refirb.

    I have been watching youtube videos the ones with the hobby chargers and load testing and all that stuff . Is that needed for this code or only for battery failure codes?

    thanks for any help !

    Yes... go in and load test the 2 modules in block 13 and replace the weak one and that should last a little while.
