calcul amperaj

buna! imi poate spune cineva cum pot sa calculez amperajul la o baterie auto daca am doar 10.8V si nu am alt aparat de masura

Si daca tineti neaparat sa vedeti care este capacitatea (in caz ca nu o cunoasteti) o incarcati pana cand la fiecare element degaja gaze ,si o puneti la descarcat cu o sarcina cunoscuta de 1-10 A;in momentul cand tensiunea la borne atinge valoarea minima de 10,5 V,verificati in cat timp s-a descarcat.Mai departe este aritmetica.

O alta metoda de calcul a capacitatii bateriei(cati amperi poate) e :Se incarca bateria complect,dupa un timp(~1h) se masoara tensiunea la borne;pt n volti corespunde 100%,pt m volti corespunde 90% din capacitate,samd.Fiecare tip de baterie are tabelul ei.Daca vrei sa afli cat are la 10,8 ,treaba asta e o utopie,teoretic bateria mai are ceva in ea dar practic nu.Oricum,la tensiunea de 10,5V o baterie de acumulatoare se considera descarcata-practic si teoretic.
