Hey everyone !!
I have problem with Cat NPV20K ser. 8JL00548. Once upon a time, value of the battery charge on LED did not corresponded the real battery charge. It happened any once when battery discharges less ~30 percent. Hydraulics is stops. When the battery changes at a full charge battery all are repeat - till the ~30 percent discharge battery - OK, and more ~30 percent discharge there is a discrepancy. I have checked by console the voltage value of battery which controller ZAPI AC-1 show in a fault state - OK (24,8 V).
What is it caused by?
Any help would be nice
Kind regards
Merry christmas !!
