View Full Version : Is it Bad?

My 8.4 900mAh battery will not charge for more than a couple of min. on my Triton. Does that mean my battery is bad?

Very likely, yes.

It could also be a bad connector or other connection within the battery, or you're trying to charge the pack at too high a rate.

I have used the charger it came with and I am using 1.2 mAh on my Triton. I get the same results with both, charger stops after a few minutes.

Try a formatting charge at 90 mA or .1amp and see if you can revive it. I always do a 1/10 C charge on my NiMh packs to balance them every month or so.

kc10boom, take a look at this thread http://www.rcuniverse.com/forum/m_3182409/tm.htm

The same sort of problem was discussed in that thread, and you may find some of the information useful.

I am new at this, how long do I charge it for at 1/10 c ?

Ooppss sorry about that. That is the overnight rate. I would go for about 10-12 hours and then check it.

If you use the Triton, it will very likely false peak, so you may want to use the NiCad setting as that likely won't. Don't forget it, or it will overcharge.

Thank you very much I will try that.

That was very helpful thank you Buzz.

That was very helpful thank you Buzz.

Did it work?

Note that even if it seems to take a charge do the overnight rate for 3-4 cycles and then do 1c charges .9 amps on the triton to see if it will take that.

I would not charge this pack higher than 1c. On those overnight charges it may not "perform" like it used to, wait till you have 4-5 1c charge cycles too get back up to speed.

Not this this will help but here is some info. Our AstroFlight 110D that we have been using for 5 years was peaking our nimh and nicad packs fast. We just assumed the batteries were bad as they are equally as old. But when we tried a new charger out testing it, we found it was the charger. It has a bad potentiometer.

So if you have another charger you might try that unless you know for a fact the Triton is working properly. Almost threw away the old batteries but they are still working with the exception of the one that fell out of my plane and was never found. Plane made it back to me on it's own. It knows it has a good home:)
