    Default NU baterii alkaline si LED-uri?

    De ce?!

    Lanterna cu LED Cree.

    Nu inteleg deloc ideea. Orice baterie produce tensiune (V) si curent/intensitate (I/A). Orice consumator e afectat negativ de tensiune nu de intensitate. El consuma atat cat are nevoie. Ce are alcalina cu led-ul?

    Nu inteleg nici eu. Alcalinele au tensiune de 1,5 V, care e problema? Ce vor astia, sa pui baterii 777 ca sa curga electrolitul si sa cumperi cate 4-5 lanterne pe an?

    Cred ca are legatura cu tensiunea maxima admisa de led,respectiv curentul suportata.Un acumulator are 1.2V nominal(1.45V incarcat complet) in timp ce o baterie alcalina de buna calitate noua masurata are 1.65V(x2=aprox3.3V in loc de 3V)
