Default 2400 nicads

My 2400 nicads have started to peak at 2200 before they were at 2500 2600 whats going on , is the mv rate to low at 15 or should i charge at a higher rate ie 5 amps.

I assume that you're running the TAC series thats the reason in running ol' 2400s...

I was wondering how old are your cells?

I charge mine using Orion's advantage charger, I set the delta peak lower than yours @ 13mv and I charge my cells @ 5amps. I usually get 2500s from my newer cells(1+yrs) and about 2200-2300s from my older cells (3yrs).

Good advice.

If there is that much of a difference in capacity between just a few charges, most likely it is just a difference of how much the pack was discharged.

True that gubbs.

Easiest way to "measure" your mV settings is to basically measure the final peak temp of the packs. You want you be at about 120-125 degrees when it stops charging. If its below that, bump up your mV setting one more. If your pack is hotter then 125, decrease your mV setting my 1 increment. But be carefull, some chargers measure the mV per cell, and then some other chargers measure the mV as the whole pack.

Example from chargers ive had

LRP Pulsar 1 - Measures the mV setting for the hole pack. So i set it at 25mV/per pack

My Current Orion Advantage Carbon charger - Measures teh mV setting per cell, so right now, i have it set at 4mV/per cell, so it calculates at 4mV X 6 cells is 24mV per pack.

Some people dont interpret the info of their chargers, or just are careless

So just remember, mV cutoff is final temp of pack, want to be around 120-125 degrees

Who said temp guns are only for nitros!!! haha


Also, another thing people dont take in effect, is that IB Intellect Cells are a totaly differnt make-up of GP Cells. GP's take a higher mV setting, while IB's take a lower mV setting. Its just the differnt make-up of the cell.

So when I charge friends GP4200 packs, I have a charge profile specifically for that type of pack, i have it set at 5mV/per cell or 30mV/ per pack. While for my IB's, I have a differnt charge profile set at 3-4mV/per cell or 18-24mV/per pack.

The reason I have it 3-4 is because the ambient temp, or the temp in the building/outside has alot to do with your final charge temp. If its hot outside, your going to have to lower you mV setting, if its kooler outside, then your might want to keep it what i have said previously or even bring up the mV setting 1 more
