Eric and Ron:
<br>Great information and guidance. I believe this type of info is
what we're needing.
<br>Thanks to both of you.
<br>As I learn more, I'll post also.
<br>I bought a Dymond charger for field use; so far haven't charged anything
except NiCds, though it automatically discriminates between the 2 types.
As far as I've used it, it works great, although limited by having only
the single outlet port.
<br>I bought the Dymond because I began to get a little nervous about taking
the Litco out to the field, and thereby possibly doing some damage that
would require service.
<br>I fully intend to have the Litco forever, but sure don't want to jump
through the hoops it would take to get another. With all the good
chargers out, I probably wouldn't do it.

Verne:
<br>Don't know if it means anything significant, but I've been concerned,
as you are, about the heat generated by NiMh batteries during charging.
<br>Only thing I can say is that I have a couple of dedicated chargers
(non-model industry related) supplied with the batteries used for a still
camera and a mini-cam. When in use, these chargers are allowing the
batteries to heat a significant amount. In fact, they get almost
uncomfortable to the touch.
<br>Feeling a little better about "hot" batteries, I've charged my NiMh
transmitter pack on my Litco. Yes, it gets hot, but, so far, so good.
<br>But, I have to admit, I'm still wary. If anything negative happens,
I'll post it to this list for others to make their decision. And,
I'm watching this list for others experiences, also.

<font size=+1>Wayne,Right now,
I have a 3000mah 12v pack for my Kavan starter. I did charge it initially
at C10 on the Alpha to break in the pack. After using it awhile, I tried
charging it with various modes in the Alpha. You don't really know what
you're charging at with the Alpha. You just tell it how many cells and
sometimes (depending on the mode) what mah the cells are rated at, and
everything is automatic after that. It's been a killer charger for nicads
but I don't feel comfortable when cells start getting warm like the NiMH's
are.</font> <font size=+1>Verne</font>

<font face="Arial"><font size=-1>What rate are you charing at and
what mil pack are you trying to charge? They will get warm but
should not get any warmer then you can handle in your hands. If it
is a new pack it should be charged at C/10 before using your Alpha.
For some reason if they are not formed properly chargers like the Alpha,SuperNova
will not peak detect properly. I seen this happen in a pack that
I didnt form properly. It wouldnt cycle at all. It would trip out(peak)
way before the battery was fully charged.</font></font> <font face="Arial"><font size=-1>I
have charged NiMh at up to 1C with no ill effects. But C/10 is always
the safest and easiest on your packs.</font></font> <font face="Arial"><font size=-1>Wayne</font></font>

<font size=+1>What chargers work well with Nimh batteries? I've tried
various settings on my Alpha 4 but end up unplugging the batteries before
it goes to trickle because they start heating up. I'm looking for something
that can be left unattended without worry.</font> <font size=+1>Thanks,Verne</font></blockquote>
