AGM baterija?


procjenjuju njenu snagu. Mislim da se takav test zove cranking test  
(CCA). To je namijenjeno za testiranje start baterija.

Mislim da bi mi bilo dovoljno izmjeriti unutarnji otpor i na temelju

A imas li neke etalonske/referentne podatke o tom otporu?

je'l?
ajder malo pojasni...


strujom kratkog spoja.

dobije kvalitetna izmjera unutarnjeg otpora baterije u mOhmima?

12.1A.








bi trebao biti realan, dovoljan bar za usporedbu.....jedini uvijet je  
dovoljna snaga otpornika i napunjena baterija....

kroz dulji period.

Npr. CCA testeri rade s velikim strujama u kratkom periodu.

Da li je netko to u praksi radio i ima empirijske podatke?

Koliko sam upoznat, ispravnost baterija se testira praznjenjem konstatnom
strujom u odredjenom vremenskom peroidu, a struja i vrijeme se odredjuju
prema krivulji praznjenja baterije do 1,85V/cl.

Da, tako se ispituje kapacitet baterije.
To je jedan od pokazatelja "zdravstvenog" stanja baterije.

Da, ali ne znas koji ti je referentni unutrasnji otpor, osim ako nisi
siguran u novu bateriju koju imas.
Zbog toga se kod isporuke baterija za neki ozbiljni sustav radi kapacitivna
proba na novim baterijama, da bi bio siguran sto ti je proizvodjac
isporucio.

12Ah unutarnji otpor nije toliko bitan, ali kapacitet je....

pokazatelj stanja baterije.

Zgodna ideja!
Tih 10 posto ekstra troska 'nadoknadis' s manjim utroskom vremena za  
testiranje....

Nije samo u teoriji nego i u praksi. A cinjenica je i da traje.

OK. Nisam ni tvrdio da bi je trebalo opteretiti strujom kratkog spoja,

Da, takva mjerenja i poredjenja s 'etalonima'
trebaju biti uz slicne struje....
