Xtar VC4L kickstarts a dead battery .

old4570 · Apr 29, 2021

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=&quot] 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=&quot]charge mode[/FONT][FONT=&quot] 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]

Did you already know what the actual volts were before the TC got it high enough to measure?

What is the digital read screen plugged into it?

thanks

A) Protection circuit has tripped , so voltage reading is zero ! ( Only way to read true voltage is to unwrap the battery )
B) Digital info = Charge rate + battery voltage for each channel .
