Hi, I have 2 different sub c cells that the triton charger never finishes charging. They are 3000 and 3300 nimh that I use in the glow driver. I charge at .3 amps and it will go at far as 5000 before the charger times out. The cells are warm but not hot. I have tried both 7 and 10mv peak detection and has no effect.


Any hints would be appreciated,,

TIA

Steve

That sounds about normal as it will take around 12-18 hrs and around 5000 calculated mah to fill the battery. I think you are close to full, but to insure it try increasing the charge rate. At the low rate it may never show a peak and may never build enough heat to feel it.

I can't seem to recall what the max time is? or the max mah input? can you?

The Triton is a Peak Detection charger. You can't charge with that low of a charge rate and have the peak detection work properly. Change the mV to 6 and charge those cells at 1-3 amps.

RC Accessory,
Unless the whole idea is to put a formation charge on new NiMh cells then the C/10 rate of charge is correct.

I think I am going to debunk or prove whether or not a battery will "peak" have a voltage drop at a certain rate (c/10)
My thought b-4 testing is that it does indeed have the same voltage drop as it does at higher rates. What do you'all think?[&:]

I particularly like a constant charge for a new pack anyways. The triton has that stopping every minute and I wonder if that is unnessecary or even harmful? I would try to prove this as well, but have no idea how?

I have yet to find any "peak" charger that will do a C/10 charge and not false peak or continue the charge for 14-18 hours which is needed for a formation charge.

In addition to the triton, I have one that I like to use it is a electrifly park flier charger (it's a peak charger,yet does not time out)

The end result is that if you want to slow charge (I rarely ever do) or do a formation charge, you need a different charger unless the peak charger you have does have a c/10 non peak charging ability. The 2 I know that do have that ability is the Alpha 4 and the Shulz 6-330D.

I personally have 4 chargers that I use.

1). Alpha 4.
2). Shulz 6-330D
3). e-Station 301
4). Dymond Super Turbo

The Alpha 4 is strapped to the wall of my work bench. Used for over night charging, formation charging, and cycling. I will also use it for peak charging my nicad tx packs. At 1 amp charge rate, it is pretty limited. I have had this charger for about 7 years, maybe longer.

The Shultz I use on the bench as well for lipo charging and peak charging my cordless starter batteries. I will also use it to peak charge nimh packs if I need to charge them on the bench. This I bought about a year ago as a replacement for my Triton. The Triton, I just didn't like it. The Shulz is also my future charger for high count lipo's. (Beyond 5 cells).

The Super Turbo is used for peak charging cordless starter batteries and any nicad packs. I have had this charger for over 4 years, worls flawless, isn't worth anything (lol) so I still use it.

The e-Station 301 is what I take to the field. Does everything I need, Nicad, NIMH, and Lipo. 4 amp charge rate is plenty. It is inexpensive and is just too easy to use.

Hi, by the way what is the max power on that 301 please?

Ok, I see it is 40 watts. I am wondering if that mutiplex charger is identical? is it 40 watts too?

TampaRCGuy

My Feedback: (282)

Tower Hobbies, Multiplex or the manua for the Multiplex do not list the wattage. My guess would be about 50 watts.

Been there, done that. I've got a Hobbico Accu-Cycle Elite. It will peak charge and terminate my 1100 NiMH 2/3 A cell 6 volt pack at the C/10 charge rate of 100 mA, with the peak sensing voltage at 5 mv. I recently got a 1950 NiMH pack and after 3 formation charges at C/10 it WOULD NOT sense the peak. My 1100 pack is 6 mths old or so and has been chg/discharged 60 times probably. On the 1950 I tried it at 400 mA charge rate/ 5mv, and it peaked just fine. Dropped it to 350 mA and it peaked ok. I'm thinking that after the battery has some use on it, it will sense the peak at C/10 charge rate. At least the Elite will, don't know about the Triton.......

RC Accessory had it right, I changed the charge rate to 1.5 amps and it terminates the charge and the both cells have over 3000 ma when I cycle them.

Thanks

Hi, thanks for the info, I may not have to "experiment" haha . When you say it did not sense the peak on your 1950 do you mean that the voltage did indeed go down? yet the elite just kept on chargeing? or something else?
