Default Charger Terms

just purchased a millenium pro
can someone explain these things to me

whats the diffrence between "ni-cd linear" and "ni-cd rev pulse"?
if i wanted a performance charge out of my millenium pro would i use another setting instead of the nimh2?

What is Trickle Charge?
What is Threshold? mv?

im looking for the safest charge possible for my 2400's at 5.0amps

You want to use Nicd linear. Nicd reverse pulse can be good for charging old packs that need a wake up.

Trickle charging is very low amperage charge after the initial peak, NiCD batteries like this, NiMH do not.

Threshold is the amount a battery is allowed to charge after it reaches peak voltage. After peak voltage is reached, you will see the voltage of the pack drop down a certain amount. You are able to set how much it drops. NiCD batteries like about 10-15mv threshold per cell, so thats about where you should set it. NiMH like between 3-8mv.

My suggestion to you, charge at 5-6 amps, 12mv cutoff with tickle charge on. Make sure you discharge the pack completely after you are done using it.

neither. a higher threshold will charge the pack for longer (more mah, more runtime) but if you go too far you can overcharge the pack, damaging or ruining it. i might be wrong but i think a higher threshold also decreases punch. the purpose of adjustable threshold is basically because different packs require different thresholds, you want to find a compromise between runtime and the condition of your pack.

I use Threshold to "set the temp". Your NIMH batteries should come off the charger at 100 to 125 F. If 4 Mv per cell (24 per pack) does not get them warm after charging, then go to 5Mv per cell (30 per pack). You will get to know your packs and charger after a wile. NO RATE or Mv setting will perform magic on your cells. Charge them at a reasonable rate (5 amps) without getting them too hot and that is all you get. It is good to have the charge end just before you start a race so they are good and warm. This is how they perform the best.

ok on my millenium pro it has a 3 settings nicd linear nicd reverse pulse and nimh2

lets just say i wanted to use threshold on my nimh. but then when i choose nimh the only settings are the amount of amps and the number of cells.

would i use nicd linear then?

You can use the NiCD linear setting, I have a millenium pro and that's what i use for my NiMH. Just set the threshold setting low enough and your packs will be great. What kind of NiMH cells do you have? I could give you an idea of what threshold to use with that info.

For your GPs use a 5 mv threshold
For your Sanyos, try 7 or 8.

Threshold is the amount of voltage drop allowed (still charging) right after peak voltage is reached. This is the point at which your batteries start to get pretty warm. Some batteries take more threshold to reach a good peak, other's don't. Most sanyo cells like higher threshold than GP or panasonic.

how bout trickle charge

im looking for a performance charge and a good safe charge for my batteries

the one you gave me would that be considered performance or safe.
can you give me some settings i can use

amps (around 6-7)?
threshold?
trickle charge?

performance/safe

sanyo 3300's and gp 3300's and panasonic 3300's
