hi thoose trucks uses curtis controller or zapi, just search manual by controller model

I don't know if yo7 realise this but the battery on an electric forklift is part of the ballast weight needed so the truck can safely lift items up to the maximin capacity of the truck. If the battery has been changed for 4x batteries which will weigh significantly less than the original battery the truck cannot then be safely and legally used

Just an update in case anyone runs into the same problem, i contacted Noblelift north America, and the guy stated that he doesnt have info on units older than 2017 but he will contact the manufacture and get back to me, to which he did a day later and he stated that those codes are related to a battery issue.

i didnt want to pay a huge amount on a battery before verifying the problem, but I thought why not try to use deep cycle 12v car/rv battery to which i did and then the forklift started working without problem, i bought 4 new deep cycle size 29 battery and currently using those to run the forklift, i know the capacity wont be anywhere close to original battery but concidering the very low usage of the forklift that i need they are working great
