So, is there a truly automatic charger for Efficient NiMH cells?

How odd. I have owned three of them. They all worked just fine with NiMH
packs for me. Full charge every time, even when
about it besides the importer's writeup.
Perhaps I should just add another Sirius to the stable.

Forgive my bluntness, I've got to chime in here.
We've been blessed recently with a cornucopia of charging choices. Nearly
all are do the job just fine subject to their intended applications. Yet,
for many the usage of them takes on a nearly mystical air. Why?
Check a charger's capabilities and
As far as chargers are concerned, for *all* types of rechargeable batteries,
I like the Schulze chargers (isl 6-330d, isl 6-430d, isl 6-530d, isl 6-636+,
and isl 8-936g). I would love the isl 8-936g, but definitely cannot afford
it. The isl 6-330d and isl 6-430d are very good -- value for money.
Are there automatic / peak detection chargers that will ramp down
enough to put a small enough charge (C/10 or so) on the tiny 200 mAh
NiMH (yep, quad A) batteries I'm using in HLG? All the ones
I've found so far run at 100 mah / C/2 for these little buggers. Even
wall warts at 50 mah
Sure, the alpha charger will. But get in line, it is difficult to get
one of these babies.

I bought an Alpha 4 about six or seven years ago and have been quite
happy with it. But (there is always a but) it did not have a
separate discharge function it only cycled (once). NiCads like to
be left discharged I have been led to believe. Ni-MH on the other
hand like to be fully charged

I use the Sirius 200 for the batteries.
After the peak charge it switches to a maintenance mode

That's the probelm with employing a NiCD charger that peak-detects for NiCD
instead of NiMH. NiMH are endomthermic, while NiCD technology is exothermic.
This means as an NiCD becomes fully charged, the increase in heat causes an
increase in internal resistance, which lowers the charge V, which

You can do much cheaper than that -- about half the price. The local
Frys sells similar sells for about 1/2 the price of what

I won't use NImH in an airborn pack at all. Fast charging them is too much of an issue. The Sirius Pro, which is rated to charge a 2000 mah pack, is only rated 1000 for NimH! NIcads are easily fast-charged, or even better, buy a second pack and change it out

I've found (on transmitter packs) that the Sirius gives up at around 60% of charge, and that to get a full pack, I have to resort to a timed charge. NOT what I want to deal with when plugging in a set it and forget it charger.
As for 40%, I do the same

You generally need to leave the packs on for about 3 hours after the lights
start blinking
