Energizer AAA's will work but in my experience are not nearly good as simililarly priced hobby batteries like Orion900, Peak900, TSR, or R1's

You dont "need" to discharge but proper maintenance will add to life and performance.

I recommend getting 2 sets of orion 900's (or similar) and a chrger like the Maha power. This charger can charge and discarge each cell individually
Batts $10x2= $20
Charger $60

You want to discharge to the same point each time... Light bulb dischargers do the job, but dont have the consistancy of voltage cutoff. You may discharge too much... You also want to discharge each cell individually rather than as a pack in series... this way each cell is discharged to the same point, so you can more easily see how much capacity each cell has when you charge them up in a charger like the Maha MH-C9000 or LaCrosse BC-900 (or even any hobby grade peak charger that charges battery packs).

I recently got a Much More CTX-D2 to discharge/match cells... and I am really liking it. It has a 3A linear discharge, which is pretty aggressive, but I feel that it weeds out the weak cells better and increases the power of the cell despite the fact that the aggressive discharge is reducing the overall life and runtime of the cells. I look at my AAA's as racing fuel. Use em up, and then replace them after a few months. No need to baby them, as they will lose power/speed anyway even if you do.

Can you adjust the discharge on the ctx-d2? I looked in a few places and saw it listed as 5amp linear, dead short, and 30amp discharge. does the ctx-d2 gives the internal resistance of each cell?

using this discharger with aaa's you can only do the 5amp linear discharge... this discharger does give ir reading but only when you do the 30 amp discharge so you wont be able to get it with the 5amp discharge...

Basically if you have no plans to race, I'd just stick with your energizer batteries. Discharging will keep the batteries in better shape in the long run but if you don't plan to race it's not as necessary for you to keep them in top racing shape.

If you ever do get into racing it would be better for you to invest in some of the batteries that we tend to race with (R1wurks, Team Orion, etc) and a good Maha or LaCrosse charger. For living room driving though I wouldn't worry too much about it.
