That is where I was a couple years ago. I had tried NiCad, rechargeable alkaline, NiMH and was disapointed with each.

These low self discharge are finally what rechargeabls should have been.
You alao need a good charger, I had spent $29 at walmart on what was supposed to be a good charger only to find out later that it rarely put more that 80% of a charge in. So I spent the $40 for a MAHA and its even recovered several of my older non low self discharge NiMH's.

I've found that LSD NiMH now last as long as alkailine within 6 months of being charged and just top all mine off at each season change or after use.
