Charger

[wgalligan]

My NiMh all get warm when charged over 500 mil.  Just before they are peaked will be the warmest.  I thought the Alph 4 was supposed to be a delta peak charger?  If so it should handle NiMh's just fine,  If the charger has a setting for NiMh it should charge ok.... but I dont own one.   I use a SuperNova and a Hangar 9 Double Vision.  The Double Vision is just a field charger that chargers at a constant rate of 750mil for transmityter and receiver pack.  The S.N. will do them all but Lithium-ion's.

  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.

    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.

    I have charged NiMh at up to 1C with no ill effects.  But C/10 is always the safest and easiest on your packs.

      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.

      Thanks,
      Verne
