Angry Charger False Peaking!

I have a Novak Millenium 1.2 charger and Trinity GP 3300 packs. It keeps false peaking. I keep having to press the charging button at least three times till the third time when the battery actually charges and gets warm. Any clue why this is happening? My batteries have about 40 runs through them.

DOMOisCOOL;

Raise the Threshold (D-peak) setting on your charger. Should take care of the problem.

The Novak chargers are famous for false peaking, especially when use GP batteries. As stated above you need to raise the threshold on your charger. You may still get false peaks bu it is not the batteries it is 99% charger.

Later,

Whats a recommended setting for the GP3300's. 6mv a cell seems high to me, i was charging at 15-20mv per pack.

Default Charger False Peaking!

Guys;

The recommended threshold settings are just that, a recommendation.

Use the HIGHEST setting that does not overheat the pack when it is done. You want the pack to be about 140F when fully charged. (very warm to touch) If it is uncomfortable (hot) to the touch, then the threshold is set too high.

Just keep increasing the setting until you get the results you are looking for.

I love my LRP Pulsar Comps, they NEVER false peak, ever.

My Millenium Pro false peaks, with the nimh2 mode, on my older packs but does fine with my newer packs. My GFX and Pitbull never false peak on any of my packs.

Your pack may have become unbalanced. Put the pack in a discharge tray to discharge each cell individually, or use the c/10 method: discharge the pack, the charge at 1/10th the C (capacity) in this case it would be 330ma. the cells that are taking longer to charge will reach full capacity because the cells that charge sooner will be able to disipate the "over charge" as heat. But don't let them go above 120 deg F.

Now use your pack and it will perform better on subsequent charges, untill it becomes out of balance again.

Basically out of balance means the cells are not matched together any more because of slight variances in the I/R which affects charge time, and discharge time. Right now, when you think the pack is "dead" one or two (or 3 even) cells may still be putting out good voltage, but the dead cells are causing resistance in the pack, making the overall voltage low.

140*F Holy crap !!!!!! 125 should be about as high as it goes . If you watch your packs , the voltage drop starts about 124
