I have started charging batteries with the VC4L ..
I got me a small collection of dead batteries and I wanted to show the VC4L charge up a 0 volt battery .
[FONT="] The battery is not really dead ! The internal voltage of the battery is low enough so that the protection circuit wont allow the battery to be charged . TC or trickle [/FONT][FONT="]charge mode[/FONT][FONT="] is engaged by the charger so as to sneak the voltage higher till the protection circuit allows normal operation . In the video you can see this process take place . ( If that floats your boat ) .
So with the protection circuit tripped , the MM reads zero volts . Anyways the VC4 deals with the battery promptly and well . [/FONT]
