[EVDL List]

Not necessarily - I have done this with cell phone and laptop batteries. Let
them sit for a few months, self-discharging, then put them on a charger for
a couple days. They will come back and be useful for a while; but they seem
to eventually lose capacity; they don't power the phone or laptop as long as
new battery's do.

I found out that if the voltage is below .50 the smart charger won't kick in
but if u some how get it to .50 it will start charging. I have used a lot of
cell phone charges different voltages form 3.7 v--1 or 2 amp 7.2v -2a & also
computer charges 12v-1000mv 15v-1a even 15v-4.6a even tried a wire form a
different 3.2 cell like a jumper but it got so hot it started to melt the
plastic off the wire & really start to smoke! before the charger would even
kick on! the best thing I have found out that work great are regular
auto-truck jumper cables, they a little bit big & a little stiff but as soon
as is connected the chargers will kick right on then after a few seconds U
can take them off the battery's who know U might even try & leave them on &
charge both of them at the same time on 12 volt! I haven't tyed that let I
will let U know what happens, later & good luck to U & every one else that
try to make things right!! onward into the night!

I have four or five dead LFP cells. I believe I have attempted to
charge each with ~3.6v. None have recovered. I wonder if should try
higher voltage? With a 6v or 12v battery charger.

Save them for the 4th of july , charge them then , but be carful when
playing with fire work. Batteries don't die , they are murdured ,, and
they where so young,,, Please tell us how there lives where cut short
so others wont suffer the same fate . Do it for the batteries , If you
don't who will .
