My experience is that rechargables can recycle max of 100 times.. =
2yrs or so..
you can be completely compulsive, labelling purchase date on each
battery, marking down discharge time on a spread sheet for each cell
etc..
- or else
price 100 AA's at a huge discount store, vs 6 rechargeables & all the
recharging equipment..

- Then add in the " Hassle Factor"

and there's your answer...
