Battery technology has changed dramatically over the past decade or so. Older nickel-cadmium (NiCd) batteries had/have an ugly habit of developing a memory. If they were discharged to the same level a few times then they would tend to "Memorize" that level and refuse to discharge below it. A "Conditioning" cycle would erase that memory and allow them to perform as new. Newer lithium ion (LIon) batteries do not have this problem and a "Conditioning" cycle is not as necessary. I use a Powerex C9000 charger on all my "AA" batteries and do cycle them through a conditioning cycle from time to time even though I haven't been convinced that it's necessary. I haven't seen that it helps or hinders but it certainly doesn't hurt anything.You could possibly solve this issue with a slightly better charger. I can't say this is true, but I suspect that the OEM and better quality 3rd party charges have some form of reconditioning built into them. My standard charger for all my AA's for strobes is built this way and reconditions batteries individually as needed.
