You can obtain Eneloops at higher capacities. The highest I have is 2450 and they work quite well.

The point if recharging is that when they are drained, you simply put in your second set and pop the pooped out batts on the charger, powered by house current, vehicle , or solar panel or whatever, and pump them up.

You can do this conservatively for at least500 cycles, while you watch the savings accumulate.

Lithium primaries definitely do have their place, and i use them s well, but my workhorse batts are rechargeable nimH's or 18650's
