Default New to electric rc

So today i revived my Traxxas e-maxx brushless and a charger (imax b6ac)

Now i very new to charging the battery's i thought it would be a matter of plugging them in and pressing 1 button, Now that i have it i have realized its not that easy
Now after a bit of reading and youtube im about to try to charged them.
Does all this look correct ?

appears i cant show images yet so ill type what the monitor on the chargers say s

NiMH 3.0A 10.05V
CHG 008:50 00406

Thank you

And if your batterys have been sitting for a while...And if your charger has a cycle mode you should cycle the a few times!!!

NiMh should get pretty hot when they peak, temp should be 120-125F. If the charger says they're charged, be sure that they are hot. Otherwise, its a false peak where the charger thinks they're charged. If they're still cool/cold, just reset charger and charge again. I've had packs where I had to do this more than once to get them to charge all the way.

Packs that have been unused for a while might need some cycling (repeated charge/discharge) as mentioned. If they don't run long, let them cool and charge them again. Look at the mah put into the pack by the charger, if the packs are getting better, this number should be going up.

What capacity (mah) are your packs? That's usually needed to determine what charge rate you want to use. I run 4000mah pack with my old Emaxx and I charge them at 5amps.

The batterys are 8,4v 3000 Mah, ive jsut come homw from work and have run the car for around 25 / 30m then i notest the battery's slowly dying which im sure that is normal.

The only weird thing i noticed last night charging is that the first battery i monitor and stop the charge after about 1hr until the mah number reaches 3000 ( is this how you do it or run the machine until it says FULL). Then u plug in the 2nd battery and only after around 15 20m the machine says the battery is full.

also few question:

What settings do i use on the charger to dischage?

Can i charge a battery that hasn't fully discharged ? Will this damage the battery in the long run

Thank you
Shane.

not all chargers have a discharge and cycle mode so you will have to look at the manual or charger itself will sometimes say if it does on it............
