I think there might be somehting wrong with my Triton. Maybe this is normal though. I'm brand new, so I don't know. Anyway, here's my situation:

I bought a brand new 1400 mah NiCd rx pack for my heli and I cycled it a few times, but the charge times seem to be too short. This last time I cycled, it only went for 22 minutes charging. I had it set to .3A discharge and 1A charge. Here's what it told me at the end:

Charge: 22 min, 347 mah
Input: 13.61V, Output: 5.43V
Peak 6.25V, Average: 4.72V
Charge/discharge: 347 / 587

I think the discharge took about an hour or so. Not sure, I wasn't timing it. Anyway, is it normal to only read 347 mah? Same thing happens with a different, older 1000mah too, so I don't think it's the battery. Possibly something wrong with the leads?

That might be the peak sensitivity.You might want to lower it but the thing is that you cannot adjust the peak sensitivity in NiCad charging but in the NiMh charging mode. So I use NiMh charging mode for NiCad charging also.

Try charging it at a lower charge rate. I find my triton gives me better results with a .2 amp charge and a .5 amp discharge. I am not an expert with it , but you might have to change the peak sensitivity settings to charge at that rate.

hopefully somebody replies if I am incorrect or any other possible solutions. I would like to know how to use it a little better too.

It's my understanding that the first charge on any new nicd or nimh pack should be done at 1/10C. I've tried fast charging new packs and got results similar to yours. Like da_man said, try a .2A or even .1A charge and you should see the correct numbers. After that, you should be able to fast charge them all you want.

Personally I would not use such a high charge rate on a new pack or any pack unless i want a quick charge,( quick charges are not healty for the packs)

for safe and "proper " charging use a rate of 1/10 the pack , in this case 0.14A , i would use 0.1 or 0.2 A to charge since the Triton only allows increments of .1

I have a triton and and robbe infinity 2 , and find that the Triton is the least reliable of the 2 two ,

You won't hurt standard nicad cells charging them up to 1C - 1.4A in this case - quick charging is only suitable for suitably rated cells and involves a current above 1C. The first charge is best done at C/11 for 16 hours but after that you're not saving them by charging at less than 1C - its one of the good properties of nicad cells. I doubt if you're done any harm charging at 1A even for the first charge - nicads are durable things.

I'd say you're leads are suspect. The Triton doesn't work well with less than good connections to the pack - thin wiring or charging through switches are the usual suspects. Try some good thick wire and plug directly into the pack.

You should get very close to the rated capacity on discharge and maybe 10-20% or so above on charge - or the pack is a dud.

You will find that by using quick charge that you will get similar results.
This does sound right. If you quick charge your pack, you will not get the same flight time that you would with a pack that has an overnight slow charge. If you can, charge the pack overnight on the charger that came with your radio and then discharge the pack on auto, your Triton will then auto charge and you should get very close to your batterys capacity. This works for me.

I don't disagree with anything being said. However, I'm a-gonna guess that you might be 'false-peaking', especially with a new pack. First, adjust the max time on the Triton to 990 minutes, so that you can do 3 proper cycles of that pack, charging at .2 and discharge at no greater than 1.4. Then you should see the capacity go up.

Most of these chargers 'sense' resistance indirectly in the way they charge, so the comments about wire gauge and switches are accurate too.

I had exactly the same thing happen to me with my triton ( and to a lesser extent with my supernova 250). After asking around I changed my leads. The leads I had were pretty long and were made from thin wire. What you want is leads as short as practical and as thick as practical. After I changed my leads I have had no trouble with my triton. Also it wont hurt to discharge or charge at 1C rate. If you have time you can do it at a lower rate.

To check the situation discharge your battery not in recycling mode.
Then charge (manualy) it with 0.3A like you did, the total charge capacity that the triton should show you should be about 1100-1500MAH . I bought a new battery of NiCD 1500MAH and new triton charger. When I first charge my battery the capacity that the triton showed bridge 1600MAH, and thats normal.
The capacity you showed is two low for charging with 0.3A and for your battery capacity.

I wasn't charging with .3A, I was discharging with .3A and charging with 1A. Now though, I'm gonna discharge with .3A and charge with .1A and see what it comes up with. I'll let you guys know if it works that way.

GRANT ED, my leads are 3 ft and look about the same gauge as servo wire. That's too long I take it? could I just shorten them up myself by cutting them or is it better to just buy shorter ones?

Leads
Its cheaper just to make your own leads if you have a soldering iron. I used 18g teflon coated wire, two bannana jacks and a HD female connector and made my own leads.

The Triton is sensitive to small gauge wire and will false peak especially when charging at high rates.

Can the banana jacks and HD female connector be found at radio shack?

EDIT: I looked at their website and they have the banana plugs, but it doesn't look like they have the right kind of connector. Do you know where I could find that?

I always solder any plugs for charging. Just me.

For ready-made plugs in different lenghts/wire gauges, try Max Products, http://www.maxxprod.com , and Radical RC, http://www.radicalrc.com .
