    lead acid batery charger

    Finnily i will use a small transformer and with a LM-317 ,i will fixed the output for a 6.88 vdc (with out the batery). Thanks to all the comunity for the answers .I  learned a lot off. Thanks for all of you.(I will use the trikle method for chargin a ni-cad cell. jose mendicoa al. venezuela...
